C352 Dead

I had exact same symptoms with a bad firmware flash screen would stay black with only the orange light showing.

I tried everything you did and in the end what fixed it was a new mfp still got the old board actually would love to recover it but I think its goosed for good. I tried many different firmwares none would work, diff nvram, diff dims, diff pcb I even tried to flash the mfp in a different machine and the symptoms followed the board so its definitely the mfp.

I cant believe theres no safe boot to flash the board but anyway...

Okay all. It was the MFP board. Swapped it and booted up. Why in the world an MFP board would die from clearing a jam I will never know!
Now I got a C-5355 fan error, off to find a bad connection somewhere!

Thanks all!

I've seen a case where a 7075 had a ICP fuse blown after the operator removed a jam. What happened was that the door sensor broke when she closed the door and the live wires made contact with the chassis.

Either that or the jam was caused by the board dying and not the other way around.
