This is a perplexing problem I have had since I acquired the 4000.
The specs: warp 040, cd-drive, 144 memory, ATX power supply, go-tek Amiga 1080 monitor.
Problem: After taking out of limbo on shelf it will not boot, no boot sound
to initialize boot sequence. Just hangs on black screen. Resets or powering down and turning
on again nothing. Eventually some attempt hours later always brings in back and then every time
after that there is no problem as if nothing ever was wrong. Now if I retire this for months or so and try again, same thing all over.
The board has been recapped. Chips perhaps or power supply issue?
