Dead Toshiba MK1237GSX

[alfarom]

I have a dead Toshiba MK1237GSX. I don't know if it's the motor or if the PCB has failed . If it's the PCB it seems cheap enough to source a replacement. I assume I have to match the board details to find the correct one and that I will have to swap the ROM chip?
What specs do I need to match and where is the ROM chip on this board?
Again, it's only practice so nothing at risk here..

I've attached pictures of the drive and a generic pcb which looks to have the same component layout as the real board.

All you need is a PCB with same P/N and switch the ROM chip @ IC602

But be VERY careful, they can be pigs to get off without the right equipment and skills. Damage that chip and you’ll be in real trouble!

But firstly check the fuse/zero ohm resistor on the power line.

pcimage is right. if you burn the rom the game will be over.

Thanks for the advice. It's not something I have the skills for if it was a customers drive.

Are there any tests I can do with a multimeter to check the existing board?

Start by measuring the voltage before and after the fuse, as already stated. Then measure the voltage at the inductor.

A proper photo would help.

I would take a ROM backup before "testing" things with a multimeter.
