It's alive again! Granted, the bad picture is still there, but it's an improvement. Turns out, the chips in the sockets really didn't want to connect unless I bent the legs in underneath the chips slightly. I suppose I shouldn't be surprise, the sockets are single wipe only and oxidized as well. So! Back to figuring out what can be done.

Regarding the screen closer, it's not the synchro.
I've the same screen before and it was 940 and 941 chips.
Which chips are those and where can I get some replacements?
