Got this in a lot of pcbs and game will not sync. I replaced the 2 pots and started to trace the sync signal back from the p7 connector. I loose it at Q12, and thought that was my problem and replaced it and get the same problem.
The signal comes from pin 25 on the ribbon cable to R92 (it does not go through K1 due to how it's jumpered). I have the signal on the base of the transistor and then I loose it. The collector and emitter are both high.
On a side note...for some reason all the ceramic capacitors have been cut off from row A1-R1. Would this affect the sync?
One photo shows the jumper and the other shows the missing ceramic caps.
Any suggestions would be greatly appreciated!
