Question CF-19 mk6 no POST after bios flash

[28_1986]

No POST after bios flash. No life except single flash from screen brightness touchpanel LED.

Swapped ram, cleared CMOS, read the bios back off the chip to check the write was OK, flashed the original bios, still no life.

Stripped the board from the machine and removed all peripherals. Still no change, just the light.

Sounds like you need a new system board, nothing you can try past what you did already.
