Running into an issues on my Cleopatra. Game boots up and plays fine. After several minutes (sometimes an hour) of playing, the drop target won't reset in between balls/games and the top bank of lights on the playfield all go out. It also starts scoring continuously when this happens. I can boot the game up the next day or several hours later and it act fine again...for a little while at least.
Power supply is rebuilt. CPU board has a brand new ROM chip. All the ground mods have been done (PS, CPU and driver board).
I did notice that the ROM chip get really hot after a couple minutes. It is socketed - could the socket be bad?
The CPU to driver board interconnect harness is OEM.
Any suggestions? Anyone make a "kit" with all the connectors for the entire backbox or have a list of all the connectors needed?
