Yep, reseated the display ROM a few times.

I resocketed the other 2 ICs below the battery which seems to have taken away the continually flashing lights stuck in a reset sort of cycle.  BUT, i have no sound

I'm thinking its something to do with a power supply/capacitor  issue(i'm really making this up, but it makes sense i my head) or something like that, the reason for this thinking is that when i initially turn the machine on (cold start) the DMD is garbled for 3 - 4 secs, then a relay clicks and it comes good.  Then 30 -60 secs later it goes garbled.  Then if i turn it off and back on within a few minutes, the DMD is always garbled. 

Whereas if i wait 20 mins or so to restart the machine (ie: another cold start) it starts garbled for the 3-4 secs then comes good again, just wondering if this has something to do with any capacitors completely discharging or the like....

Make any sense?
