I can recover rom for this model.

Normally to fix this PCB you would remove the shorted 5V TVS diode and run a wire from the diode's cathode pad to the +5V pins at the SATA power connector.

I don't fully remember if the SAP file is 3F in other families so you may want to check the system file directory of your patient drive before moving the PCB to the patient drive.

without native sap it won't be able to lick anything up from the SA.

Without wishing to interrupt the discussion on rebuilding the rom .. what is the likelihood the OP's rom is actually bank ? There have obviously been power issues but enough to blank the rom entirely, Id have expected to see some signs if that were the case.

OP - can you read the rom in an external reader, it doesn't look to have been off the pcb.

Have you checked if preamp is OK? there's a chance to kill the data if preamp is gone and you power it up with a donor pcb....
There's only mathematical chance it would read anything from the SA using a donor rom.

Yes - Externally Read the ROM - IT IS BLANK.

ROM in Video is DONOR PCB (that why it is not Blank)

DONOR PCB (and ROM) seems good - Drive is not making NOISE and stable after INIT.

Oh, i missed that, in fact i didn't think you would post a video with donor rom, as it is really pointless unless you want to check if your tool reads rom properly.

On the other hand, how did you try reading patient ROM? Have you tried external readers? MRT won't get anything from a damaged pcb even if ROM is fine.

1. Tried Damaged PCB - Successful But BLANK. ( it is clear, INTIALLY ORG ROM is BLANK).
2. Tried Good PCB ROM READ - Successful.

Have you tried external readers? Yes

with desoldering the patient rom?
coz you may not be able to read it in circuit if the power rail is shorted for example.

soldered it to donor pcb?
