I have a Jungle King boardset that shows bad graphics. The game plays but the graphics along the top and bottom on some screens are bad.
I have a working boardset and was able to narrow the problem down to the last board, the CPU board.
I exchanged all socketed components with the working boardset, however it did not make a difference...
So where do I go from here, besides a standard visual inspection of the board? I did notice some green inside one of the sockets (for ROM 60) which may be something (any idea what I'd order for a replacement socket?)
Any tips on how to check things would be appreciated. This board has allot of soldered chips on it as well...I have a logic probe and multimeter, but am not sure where to start (or continue!) and how...
Thanks!
