Would appreciate any help, it's a bummer to have a Tommy with nothing showing on the screen!
Quoted from Ive:
You have tried the obvious thing I take it - reseating all the display ROMs ?
The good: the display comes on now, appears mainly due to flipping the display cable on the Display controller board (believe ColorDMD install instr. said put pin 1 to right, it's on the left now and display came on, maybe it's due to the replacement Stern board instead of DE?).
The bad: display freezes and then turns off. When I unplug either end of the display cable the Rom msg comes on and sometimes the display "recovers" and works normally into the beginning of the first ball if I quickly replug the cable, then freezes again. Can most consistently get display back by sliding display cable on/off connector at CPU board (but also works to do it at display board). Can't find any consistent way to get display to stay on or not freeze. Machine does seem to have other minor glitches related to this, sound will delay when display glitches sometimes, ball sitting in VUK but machine has lost it, power down and on recovers...CPU board problem? Thanks for the help.
