Hi,
I hope some one can help me. I have a WPC Dot Matrix Controller Board
(A-14039) that I am having problems with. When first powered up, the
DMD has garbage all over it and is not blank like when using a good
Controller board. When the High scores are shown, the display looks
good and shows all the correct characters with the bad board, just
like the good board. When it goes into the "Drugs screen", I can see
the words but have garbage characters on all over the screen. Someone
in the past has worked on the board and the RAM has been replaced with
a socket/chip (I also checked with good RAM from the other board). I
know all of the cables are good (and oriented properly) and the display is also good, so I have it pinpointed down to the components on the Controller board. Has anyone experianced this before with a Controller board?
Here is a video of the issue:
