Hi,

I picked up an e5000 with blank screen call, advised beforehand that it was non-functioning. I've tried swapping out; memory, Flash, Rom and floppy. Also the power supply and front panel. But it remains non-functioning with the blank screen it eventually goes to most of the LED lit.

I wonder if there's anything else I may try?

All the individual components referred above seem to function in the working unit
