Quick Buying Check
Buy this when
- Red X Icon: Use the logic-board check only after battery, storage, display, controls, audio/Hold, dock, and connector assemblies are ruled out on this model.
Diagnose first when
- Match the removed board marking before ordering; A1238 alone is not enough.
- Before buying this logic board, separate charging and power, storage, LCD, click-wheel controls, headphone audio and Hold behavior; note what changed after any recent repair and which checks were actually completed. A red X or a no-power symptom alone does not select a board.

Diagnostic Failure Cards
Use these model-specific failure cards to decide whether this logic board is the right part, a nearby part needs checking first, or escalation makes more sense after simpler checks.
| Symptom | What it means & what to check |
|---|---|
| Symptom remains after basic checks |
What you may see: The iPod still points back to Factory Original Logic Board (2007 80GB/160GB) after cable seating, battery stability, and nearby connector checks. Check first: Retest with known-good cables or adjacent parts where practical before ordering. Check next: A nearby cable, connector, battery, storage device, display path, audio path, or board path can mimic a bad logic board. |
| Symptom changes when touched or reseated |
What you may see: The symptom changes after moving the part, reseating a cable, or applying light pressure near the connector path. Check first: Inspect the connector, latch, flex, solder joints, and nearby board area for damage or corrosion. Check next: This can still be a connection issue rather than a failed logic board alone. |
| Problem began after another repair |
What you may see: The issue started immediately after opening the iPod, replacing another part, or disturbing an internal cable. Check first: Reopen only as far as needed and inspect the exact area touched during the previous repair. Check next: Post-repair symptoms often trace to seating, latch, screw, or cable issues before Factory Original Logic Board (2007 80GB/160GB) itself is confirmed bad. |

Repair considerations
Run these checks before replacing the logic board — they confirm the logic board is the right fix and not a nearby fault:
- Escalate board-level soldering or connector damage
- Replace or professionally rework logic board
Do Not Buy / Problems This Logic Board Does Not Fix
| Situation | Start here instead |
|---|---|
| Variant or capacity does not match this listing | Use the Factory Original Logic Board (Late 2008 120GB / 6.5G) listing instead. |
| A replaceable attached-part path is isolated | Test the likely battery, storage, screen, audio, cable, or connector path first. |
| Recent service or connector disturbance is the main clue | Reopen carefully, reseat the part that was disturbed, and inspect its latch before buying a board. |
| You see a folder icon, clicking noise, or restore failure | A folder with an exclamation mark means the iPod cannot find its storage — the drive, its ribbon cable, or the software on it. Check the drive or flash media, storage cable, adapter seating, formatting, and restore path before replacing any part. |
| The problem is the Hold switch or headphone jack, not this part | Diagnose the exact-model headphone-jack/Hold assembly and its connector before choosing another part. |
| Only the screen is affected and everything else works | Start with the screen, display ribbon, and backlight path before replacing the logic board. |
| Cable, computer, sync, or port behavior is the primary problem | Use the nearby battery, storage, screen, audio, cable, or connector listing that matches the symptom first. |
Install Overview
Before You Start
Turn Hold off, use the reset sequence for this generation (hold Menu + Center until the Apple logo), and confirm the model and variant before opening the iPod.
Treat case opening as the highest handling risk. Work around the seams gently and stop if the shell, clips, or internal stack resist.
Do not pull the halves apart or side-load board sockets. Reseat nearby ribbons and connectors before blaming a replacement logic board.
Test known-good replaceable assemblies first so the board is not blamed for a battery, storage, cable, control, screen, or audio path.
Do not fully separate the case halves until the remaining ribbons are released; the back panel can still be connected by ribbon cables.
Disassembly Guide
Disassembly guide summary: iPod Classic Logic Board Replacement.
Show all 41 installation steps
This iPod case is unusually hard to open without damaging major components. Its metal faceplate, metal backing, and thirteen metal clips make disassembly especially demanding. Caution: this opening method can significantly damage the iPod beyond its current condition. Keep a few extra plastic opening tools nearby, since they are easy to ruin while opening the case. Confirm that the hold switch is locked before you open the iPod.
Opening this iPod is challenging, so do not get discouraged if it takes a few tries. Watch the plastic opening tool tip angle as you insert it into the iPod; keep it as vertical as possible while still clearing the rear panel edge. Guide a plastic opening tool into the seam between the front and rear of the iPod.
Slide a second plastic opening tool into the seam between the iPod front and rear, keeping the two tools at least 1.5 inches apart.
Working at an angle, carefully slide a putty knife about 1/8 inch into the gap between the two opening tools. You will find thin metal rails running along the inside of the back panel, so work very carefully when inserting the putty knife. After the putty knife clears the rear panel lip, rotate it vertical and carefully but firmly work it straight down through the opening tool gap.
Press on the rear panel behind the putty knife with your fingers to reduce bending. Slowly flex the putty knife so most metal tabs along this side of the iPod release. The idea is to control how the rear panel bends instead of trying to prevent all bending. Any side bend should draw the rear panel lip away from the iPod, not push outward on the curved surface. This also releases as many side clips as possible.
Take the putty knife out, then place it closer to the iPod corner and use the same gentle wiggle method. If possible, do not bend the rear panel corner.
Near the headphone jack, guide a plastic opening tool into the seam between the front and rear of the iPod. It may be easier to flex the putty knife downward carefully to create more room for the opening tool. Be careful not to bend the rear panel corner.
Near the display center, carefully slide a metal spudger into the gap made by the plastic opening tool. A visible bump can form here in the rear panel and is hard to repair. When levering the tab free, pivot the metal spudger on the rear panel edge instead of bending the rear panel outward. With the metal spudger, release the single clip at the iPod top edge.
Near the other top corner, guide a plastic opening tool into the seam between the front and rear of the iPod
On the other side, use the opening tool to start the same case-opening gap. It may help to angle the tool stuck in the top corner to create enough room.
Take the opening tool out of the top corner, then slide it into the seam between the iPod front and rear. Keep at least 1.5 inches between the two tools, as on the opposite side.
Working at an angle, carefully slide a putty knife about 1/8 inch into the gap between the two opening tools. Again, you will find thin metal rails running along the inside of the back panel, so work very carefully when inserting the putty knife. After the putty knife passes the rear panel lip, turn it vertical and carefully but firmly work it straight down through the gap between the plastic opening tools. Press on the rear panel behind the putty knife with your fingers to reduce bending. Flex the putty knife just enough to make sure most metal tabs along this side of the iPod release.
The metal clips near the corners grip the front panel tightly. Release these clips before opening the iPod. Carefully slide a metal spudger into the area beside the stubborn metal clip.
Gently work the metal spudger downward until it is fully seated in the rear panel.
Gently start releasing the clip from the front panel. A visible bump can form here in the rear panel and is hard to repair. When levering the tab free, pivot the metal spudger on the rear panel edge instead of bending the rear panel outward.
Use the metal spudger to apply upward pressure under the front panel until the metal clip releases.
You will find two ribbon cables connecting the rear panel to the remaining iPod assembly. In the following step, take care not to damage these ribbon cables. In this step, grasp the front-panel assembly with one hand and the back panel with the other. Pause for a moment before continuing. Very gently release the remaining rear-panel clips by pulling the tops of the front and rear panels apart, using the iPod bottom as a hinge. Take great care not to damage the ribbon cables joining the two halves.
With a spudger, slide the connector upward where it holds the orange battery ribbon. Lift the locking bar only about 2 mm to release the cable. Move the orange battery ribbon out of its connector.
Set the rear panel beside the iPod, taking care not to strain the orange headphone jack cable.
Raise the hard drive with one hand to expose the headphone jack ribbon underneath. With a spudger, flip up the plastic tab securing the headphone jack ribbon in place. The tab can rotate up 90 degrees, releasing the ribbon cable. Move the orange headphone jack ribbon out of its connector. The rear panel is now released from the iPod.
After opening, check the lower-case clips. If any clip bent upward, press it back down gently so the rear case can close cleanly.
Use the broad, flat face of the metal spudger to press the clip downward. Work carefully so the thin metal rail does not tear away from the rear panel. While shaping these clips, take care not to damage any headphone jack parts.
Set the rear panel on its side on a clean, hard surface. Carefully but firmly press it downward, rolling the full lip edge back into place. You may need to repeat this several times to straighten the sides well. Slightly overcorrecting the case edges inward is better than leaving them too far out, because reseating the front panel will bend the rear panel back into alignment. Once the rear panel is restored to good condition, continue with the iPod repair.
Rotate the hard drive out of the framework, then set it with the connector facing upward. With a spudger, lift the small black locking tab for the orange hard drive ribbon. The tab rotates upward 90 degrees and frees the ribbon cable.
Move the orange hard drive ribbon cable straight out of its connector. Keep the drive's rubber mounting brackets and foam padding in place for reassembly.
Take out the three Phillips screws that secure the front panel to the metal framework.
Rotate the iPod 180 degrees and take out the 3 Phillips screws holding the front panel to the metal framework on the other edge.
In this step, gently work around the edges of the device to separate the front panel from the gray metal framework. You may meet some resistance, as you will find a mild adhesive used to help hold the two parts together.
Lift the full framework away from the front panel; it carries the screen, logic board, and click wheel. Confirm the click wheel button is seated before reinstalling the framework in the front panel.
The front panel is now released from the iPod.
With a spudger, lift the plastic tab that holds the orange display ribbon. The tab rotates upward 90 degrees toward the display and releases the ribbon cable.
Move the orange display ribbon cable directly out of its connector.
Raise the framework assembly up, and move the display and LCD metal backplate out of the framework assembly.
Take out the two Phillips screws securing the logic board to the framework.
Carefully press the logic board away from the metal framework. Mild adhesive secures the logic board to the framework. Take care not to bend the logic board by pushing too hard in one spot.
Move the click wheel out from under the logic board until its icons are visible. With a spudger, flip up the plastic tab securing the orange click wheel ribbon in place. The tab can rotate up 90 degrees, releasing the ribbon cable.
With a spudger, raise the click wheel cable off the logic board. Take care not to over-bend the cable, since its electronics can be damaged. When reinstalling the click wheel, make sure the click wheel cable is fully seated in its connector.
Move the click wheel cable out of its connector. Raise the click wheel assembly away from the logic board. Do not forget the click wheel button when putting your iPod back together.
With a spudger, flip up the plastic tab securing the orange hard drive ribbon in place. The tab can rotate up 90 degrees, releasing the ribbon cable.
Move the orange hard drive ribbon cable straight out of its connector. If adhesive holds the cable to the logic board, carefully pull up on the cable to loosen it.
The logic board is the remaining assembly.
Product-specific placement, reassembly, and check
- Prepare and access. Confirm the exact model and listing fit first. Use the existing steps as a disassembly guide, gather the specified tools, disconnect power where applicable, and keep screws and cable positions organized.
- Place Factory Original Logic Board (2007 80GB/160GB). Install only the exact board variant after every adjacent cable and assembly has been isolated, then reconnect each interface in its original position.
- Reassemble without force. Reverse only the access steps needed for this repair, keep cables clear of case edges and screw posts, and close clips in stages.
- Validate before final closure. Before final closure, validate startup, charging, storage recognition, display, audio, and controls; a generic symptom alone is not proof of a board fault.
Stop condition: Stop if a connector, latch, screw, clip, housing edge, or the replacement part resists normal alignment. Recheck model fit, orientation, cable routing, and trapped hardware instead of forcing it.
After This Repair
| Check | What to do |

Disk Mode on the iPod Classic: Stuck In It, or Can't Get Into It
Disk mode is the iPod Classic 6th generation's built-in fallback: a bare USB-drive mode that loads before the normal software, so a computer can reach the hard drive even when the iPod itself won't boot. That is why it shows up in two opposite complaints — iPods that get stuck living in disk mode (the "Do Not Disconnect" / "OK to Disconnect" screens), and iPods with a red X that refuse to enter disk mode at all. On this hard-drive-based model, what disk mode does or doesn't do is the single most telling at-home test of whether the drive, the ribbon cable, or the logic board is your problem.
Anecdotal owner reports (not a guarantee or authoritative proof): - An owner's 80GB Classic got stuck in disk mode: the computer saw it as a drive, but iTunes never recognized it, and the PC could not format it no matter what. That half-alive state — visible as a disk, but unable to complete a format — is the classic signature of a drive with failing sectors rather than a software glitch. - A 160GB thick owner replaced his hard drive ribbon cable with what he thought was the right 160GB part — and got the red X with diagnostics reporting no hard drive at all. He had hit the trap on this model: the original 2007 thick 160GB takes its own longer cable, made for its CE-ATA drive and not interchangeable with the thin 80GB/120GB ribbon, and the wrong one leaves the drive completely undetected. - One 80GB owner went all the way down the rabbit hole: restores completed in DFU (a black-screen recovery state, not Disk Mode) and then the iPod demanded restoring again, the original drive would not format even when removed and tested on a computer directly — and a known-good drive also refused to restore, throwing errors 1430/1431. Every other diagnostic test passed. When a working drive still won't restore, the logic board moves to the top of the suspect list. - Another owner fitted a brand-new drive and still got the red X with no disk mode; diagnostics reported a drive present, but the computer's disk utility never showed it. The advice that settled it: a cheap ZIF-to-USB adapter lets a computer test the drive directly — if the computer detects it, the drive is good and the fault is elsewhere (the thick 160GB's original drive is CE-ATA, so that test needs an adapter that supports CE-ATA drives). - One owner's Classic froze on the Do Not Disconnect screen in both restore mode and disk mode: iTunes saw it and prepared a restore, then the iPod dropped off the computer, and the drive showed up as a volume that could not be formatted and failed its cyclic redundancy check. A drive that fails that check is most likely failing, and replacing it is the fix.
How it usually progresses: - The won't-enter-disk-mode track usually builds in stages: songs start skipping or freezing mid-track, the drive gets audibly noisy or clicky, iTunes begins freezing when the iPod is plugged in — then one day the boot stops at a red X, and disk mode won't take. - The stuck-in-disk-mode track often starts with an interrupted or failed sync, format, or restore: the iPod retreats to the 'Do Not Disconnect' / restore screen and stays there through resets. Restores may appear to finish and then loop right back — a sign the drive is no longer committing what iTunes writes to it. - A flat battery can mimic the worst stage: an iPod that reboots every couple of seconds resets too fast to hold any button combination, so disk mode and diagnostic mode both seem broken. Apple's own disk-mode procedure starts with verifying the iPod is charged — owners who charge 20–60 minutes first often find the modes work again.
What typically causes it: - Why 'won't enter disk mode' points at the drive: even disk mode needs to reach the storage. A red X means the iPod cannot reach a usable storage path, and when disk mode refuses on top of it, the path itself — drive, ribbon cable, or its connector — is down. Repair veterans confirm the drive by plugging it into a computer with a ZIF-to-USB adapter before buying anything (match the adapter to the drive: the thick 160GB's original drive is CE-ATA, not the thin drives' PATA/ZIF). - The two-cable trap: thin 80GB and 120GB Classics use one ribbon cable; the original 2007 thick 160GB uses a different, longer cable built for its CE-ATA drive. The two are not interchangeable — install the wrong one and the drive simply never appears: no disk mode, no drive in diagnostics, red X at boot. That applies to the original drive only: a flash adapter fitted in the thick case uses the thin ZIF ribbon (sold separately), never the CE-ATA cable. - Restore loops aren't always hardware: restore failures such as error 1439 are also produced by third-party cables, USB hubs and other USB devices on the computer, alongside a genuinely failing drive. Before condemning parts, retry with the Apple cable on a USB 2.0 port at the back of the computer with other USB devices unplugged, and force disk mode for the restore. - On flash-converted iPods, a restore-then-back-to-disk-mode loop is often the card or the adapter rather than the iPod: card compatibility varies by exact adapter and media batch, so try a known-compatible card before buying anything else. - A diagnostic screen may ask you to Plug in FW. Without a FireWire power source, skip that test; its waiting state is not a drive-test result. This Classic supports FireWire charging, while syncing uses USB.
Handle it safely: - Restoring wipes the iPod completely. If your music exists only on the iPod, get into disk mode first (reset, then hold Center + Play/Pause) and copy your files to a computer — the music folder is hidden but can be unhidden from the computer side — before you let iTunes — on Windows, iTunes for Windows or the newer Apple Devices app — restore anything. - If the iPod is resetting every few seconds, don't fight the buttons — charge it on a wall adapter or computer for 20–60 minutes first. The disk-mode and diagnostic combos need the iPod to stay up long enough to register the hold, and Apple's procedure starts with a charged iPod for exactly that reason.
iPod Classic 6th Generation Won't Charge: What Owners Describe
Charging complaints on the 6th Generation Classic range from a charging screen that never clears to an iPod that only charges from one particular source. The reports below are paraphrased from owners and are anecdotal; several different parts can produce the same picture.
Anecdotal owner reports (not a guarantee or authoritative proof):
- One owner reported being stuck at the Please Wait, Low Battery screen.
- Another owner reported that the Charging, Please Wait screen remained even after a battery replacement and multiple charging attempts.
- After replacing both the drive and the battery, one owner found the iPod asking for a restore on a wall supply and sitting on the charging screen on a computer, and the old battery did no better.
- One owner's iPod has charged only from a computer ever since a battery swap years ago; a string of USB wall adapters never charged it, and a second battery swap changed nothing.
- Another owner's iPod charged only while in the connected state on a computer; once ejected the charging icon vanished, which made wall chargers and power banks useless.
- One owner with a recently fitted battery could not get any current Apple charger to charge the iPod.
How it usually progresses: - A deeply drained battery is the usual first stage: the iPod shows the charging screen, a low-battery warning, or nothing, and cannot even talk to the computer until it has taken some charge, which is why the standard advice is a known-good high-power port or an Apple wall adapter before judging anything.
What typically causes it: - The charging path has four usual failure points: a dock connector fouled with dirt or corrosion or with bent pins, a wall adapter the iPod will not charge from, a battery connector that has lifted off the logic board, and a battery drained below the cut-off the power manager will accept. - A charging fault that appears right after a battery swap is very often the connector, not the cell: the battery connector on this board is easily torn off during a battery swap, and a lifted or half-seated connector gives a won't-charge or charges-only-when-cabled picture that a new battery cannot fix.
Handle it safely: - If a wall charger will not start a charge while a computer port does, try an Apple USB power adapter before blaming the dock connector: this generation is particular about wall adapters, and the Apple adapter is the reference for that check. - Do not charge from a keyboard or unpowered hub port and expect a recovery: a battery this flat needs a high-power USB port or a proper wall adapter, and only after that charge do the reset and disk-mode combinations mean anything. - If you open the iPod to reseat or replace the battery, lift the brown lock tab straight up about 1 mm with tweezers or an opening tool, never sideways and never by the white housing, and confirm the ribbon is fully home with the latch down before closing up; a connector torn off the board is a logic-board repair.
iPod Classic 6th Generation Not Recognized by the Computer: What Owners Describe
An iPod that the computer or iTunes no longer sees can be the cable, the dock connector, a battery too flat to answer, the drive, or the board. Owners' paraphrased reports below are anecdotal; none of them on its own identifies the failed part.
Anecdotal owner reports (not a guarantee or authoritative proof):
- One owner reported that the iPod stopped appearing on a computer and barely charged, even after trying several cables and disk mode.
- One owner's 160GB locked up iTunes the moment it was plugged into a Windows machine (audio kept playing but nothing could be clicked), and unplugging it produced a message that the iPod could not be synced because a required folder was missing.
- After a logic-board replacement one owner's 120GB worked except that it listed no music and the computer reported an unknown device.
- A 160GB owner's iPod ran fine from an external power source but did nothing on a Mac or a PC, so no songs could be added and no backup taken.
- Another owner's iTunes opened on connection, failed to recognize the iPod and then froze; after many tries a friend managed a firmware update and restore.
How it usually progresses: - Owners separate the connection from the iPod: a different cable, port and computer, and a look at the 30-pin dock connector for bent or corroded pins, come before any part is ordered; an iPod that misbehaves even when it is not plugged in is a drive or board story rather than a connection story.
What typically causes it: - The 30-pin dock connector carries both the data and the charge, so bent, corroded or dirty pins stop recognition first; check it before anything inside the case. - An iPod that freezes iTunes and the file manager the moment it is connected, and whose diagnostics stall on the FireWire check, is usually a failing drive rather than a connection problem; the FireWire stall itself is normal on this USB-synced generation, which only charges over FireWire and never syncs over it.
Handle it safely: - Work the cheap end first: clean the dock connector with isopropyl alcohol and compressed air, try another cable, another port and another computer, and only then start on the battery and the drive; restore errors such as 1601 and 29 are isolated the same way.
Frequently Asked Questions
Use these questions to narrow the part path before ordering. They keep each answer focused on a different diagnostic or fitment decision.
What iPod Classic 6th Generation models does this fit?
This Factory Original Logic Board (2007 80GB/160GB) fits: MB029LL/A (80GB Silver), MB147LL/A (80GB Black), MB145LL/A (160GB Silver), MB150LL/A (160GB Black), MB562LL/A (120GB Silver), MB565LL/A (120GB Black).
Do I need to solder?
No, this installation does not require soldering. Difficulty: Very Difficult. Estimated time: 1 - 2 hours.
How do I know if this factory original logic board needs replacement?
These symptoms require exact-model diagnosis first; consider the logic board only after power, storage, cable, display, audio, and control checks isolate a board fault. Check fitment, connectors, and nearby parts before treating symptoms as proof.
What else should I replace at the same time?
Replace a battery only when its condition, fit or power checks call for it; opening the iPod is not itself a reason to buy one. Choose flash storage only if you want a conversion and have confirmed the board, firmware, adapter and case arrangement. Match the storage ribbon to the installed drive: thin ZIF for the supported flash route, including in a thick shell; 821-0546 CE-ATA for the original thick 160GB mechanical drive.
How should I use power, charging, or runtime symptoms to choose this logic board?
Check battery variant, battery connector, FireWire power, charger/cable behavior, and storage spin-up load before board replacement. Board diagnosis is stronger when the iPod remains dead or unstable after known-good battery, cable, dock, and storage checks. Test with a known-good charger and cable before opening the iPod. Note whether the iPod shows charging, briefly powers on, shuts down under load, or never wakes at all. If the symptom began after service, inspect the battery connector and nearby flex paths before replacing another part.
Could another part cause the same symptom?
Use the Quick Buying Check, Failure Signs, and Do Not Buy sections together before ordering. The symptom should still point to this logic board after nearby parts and fitment are separated.
What should I check after liquid exposure?
Unplug every cable, turn the iPod off and slide the Hold switch on before anything else — do not keep trying to charge it. Open it, disconnect the battery, and inspect the logic board and every connector for white or green residue; clean with high-percentage isopropyl alcohol and a soft brush, keep the hard drive out of any liquid, let everything dry fully, and only then reconnect power and test with a known-good battery (lithium cells react badly to moisture). Corrosion that survives cleaning is board-level work; liquid visibly inside the display glass never comes out and means a new panel.
Why is there no menu click or beep?
Check the Clicker setting. The internal clicker is not a music-playback speaker; headphone silence follows the separate jack and audio diagnosis.
What Owners Report
These are anecdotal owner reports, not guarantees or authoritative proof that a particular part will fix a symptom. Use them as a troubleshooting starting point: confirm the symptom, run the quick checks, then match the fix.
30-pin connector: damage, docks, and modern hookups
Symptoms. Blinks on and off with a soft click and only while plugged in; broken 30-pin connector; video won't play out through an older video dock; wondering how to connect the Classic to a modern car.
Check first. Blinking with clicking, dead unplugged: battery and connector first, then the port for debris or bent pins; the clicking is the drive. Dies partway through the built-in diagnostics? Loss of power can stop a test completing — charge or swap the battery and re-run.
The port. Soldered to the logic board — replacing it is board-out micro-soldering, not a snap-in part; past that, this board is the part.
Docks and cars. Video needs an AV cable or dock that identifies itself to this Classic. Video docks and cables made for the earlier iPod with video are a different platform — see that model's pages. Modern car: aux input, or a 30-pin adapter confirmed for this Classic — owners report cheap pin adapters powering it without audio.
Community signal. Reported by 5 owners.
Recognized by the computer but not by docks — or vice versa
Symptoms. Works and syncs on the computer but a HiFi/speaker dock ignores it; syncs then self-ejects seconds later; "USB device not recognized"; plays on a dock but won't run on battery or sync over USB; partial sync then errors.
Checks — none proves the cause for every unit.
- Dock ignores it but USB is fine: try another device on the dock, and the iPod on another dock.
- Sync-then-eject: turn off automatic syncing and retry; wall-charge first (a near-empty battery can brown out on connect); then cable or storage.
- Runs on a powered dock but not on battery or USB: battery first. Partial sync then errors: cable and port, then the drive pages.
Fixes. Clean the port (alcohol, compressed air). Still deaf on the dock side: the port is soldered to the board (solder-level work); board-side damage means this board, matched to your unit.
