Hello friends. I'm here only to be sure that my diagnosis isn't erroneous.
This Grenada came to me with the PCB completely destroyed by an IT store.
Changed the PCB and I'm getting this on terminal:

Boot 0x40M
Spin Up
RECOV Servo Op=0100 Resp=0005
TCC-001E[0x000042F9][0x000042F9]ZZZZMMMMMMMMMMMMMMMZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMddddddWW
PreampFaultStatus = 0000YWMMMMMM

Drive doesn't sound weird and stays on BSY all time.
This is clearly a preamp problem, right? Is there any chance to be anything else?
Thank you so much for any reply.

Did you swap rom to the new pcb?

bojack, Yes.. it's spinning and heads are posting (hearing through a stethoscope). Sounds are totally normal.

Did you check the rom before? I guess ROM is not native. Do you have a pc3k or any special tools?

Firstly check Hdd id, serial number etc from the Rom.

I have a MRT pro.. didn't check the ROM... now that you said it's really possible that this IT store changed ROM or something like that.
Where exectly on ROM dump should I serch for this, please?
I'll check this today and I will come back.
Thank you for your reply.

I could tell but I never used Mrt.

bojack, I believe it will be on .bin hexadecimals from ROM, right? This can be readed with any hexadecimal editor, right?

If you can read the rom and upload it here, i can check for you.

Ok, thank you. I'll do this ASAP.

Where was the damage on the original PCB? If the 5V TVS diode is shorted or missing, then the preamp may have been damaged as well.

Check the ROM's CAP module for the serial number and model number.

fzabkar, It were totally destroyed. Some animal tried to "reflow" MCU and drive controller chip. Lot's of poor flux. It was a mess.
But it really can be other PCB, not the original, judging by what they made to this poor PCB.
I'm sending the ROM .bin. Where exactly should I search for serial and ID?

On label serial is Z1D09FLM
PN: 9YN162-570
FW: CC98

Thank you again for all your help.

Found it... this isn't the device's label ID... now I will ask him if he can contact the IT store that committed this crime.

F3RomExplorer should be able to parse the ROM for you.

fzabkar, Nice, Thank you

This PCB has two SOIC 8, one next to the other.
My donor PCB have two, but the original PCB came with only one.
What is the difference?
The PCB is 100664987 REV B

Not much surprise. For some reason the original card is always lost.

What are the markings on the ICs?
