Not a Match? Try our PCB Finder
  1. Locate the number imprinted onto your PCB board (circled in our picture), it should say OA90158.
  2. The number on the sticker on your circuit board should say OA29989.
  3. Verify the number on the largest square chip on your board is: OA58786.
  4. If the above are matching, then we can make a clone of your board. We will need you to mail the dead circuit board to us.

    5. To make the clone, we will need you to fill this form, then ship your DAMAGED PCB (circuit board) to us. We will then copy the information from your PCB onto our PCB. We will then ship the working cloned PCB back to you. (To find out more, please read our article by clicking here.)

    This process is necessary to ensure compatibility, a direct replacement without the firmware transfer is not compatible.

When to buy this item:

We recommend buying this item when you are sure it is the PCB. For example, if there was a power surge, or some components are obviously burnt, or the wrong power adapter was used to power up the drive. If the drive will not spin up at all, and wasn't dropped, chances of success with replacing the PCB are quite good.

There are no refunds with this purchase, so if you would like to describe the specific symptoms to us, please Contact us through our online form or at info@pcbsolution.com, we will try our best to reply within 12 hours.

Item Includes: circuit board, firmware transfer and installation instruction sheet
