Pioneer BDR-XS07 Repair Attempt

[mitchkramez]

I'm in the middle of a repair attempt on a BDR-XS07 drive that doesn't respond at all when plugged in. I'm still tracing power to confirm it's getting everywhere it needs to go, but I'm hoping someone can shed some light on flashing the bios chip out of circuit in case power is all good and this was just a bad flash - I have a programmer, but i'm curious if these drives need the ROM chip flashed and maybe also some additional stuff flashed beside the mx eeprom on the board?

Currently the board isn't recognized at all when you plug it in, but i've been able to confirm the main fuse appears to be good, still need to trace it to the rest of the chips with datasheets. If anyone has any details that might prove helpful, any direction would be appreciated

Hoping @coopervid might pop in here...

Flashing is just software based in Windows. You seem to have a hardware problem and so flashing can't help.

Thanks @coopervid, I guess I was keeping the possibility that the drive wouldn't do anything if the firmware was corrupted somehow, but I'll keep going on my diagnostics and hopefully just find a bad component that needs replacing. All i want to hear is that "usb device recognized" sound in windows when i plug it in, then, hopefully I can get it back together again, these slot load drives are quite complex in their mechanical action!

I read several times that the USB->SATA bridge went bad on these drives.
