Hello all. I am helping out a buddy to try and get his ms pac man arcade game working. The previous owner said it was working (but had to wiggle the rf board once in while to get it going) However, when we got it, it was not working at all . I was able to get it to finally power on after removing the rf filter board and some new fuses.
But now when it is on we just get a screen of garbage and a constant clicking noise of some sort. I looked up a few posts and the screen looked similar to some I saw which said the sync bus board was damaged/not detected. I tried re-seating it with no change. If I remove the sync bus board all together the clicking stops and the unit remains on.
Thinking that was the issue we got a second sync bus board, but the problem persists.
My next thought was to replace the socket for that board. While I was doing that I thought I would check and see if there was anything else I should check out or go ahead and replace.
The machine is not at my place, so I can get additional information if needed, but it may be a little slow for him to relay it to me. I have attached an over all picture of the board he sent me as well as what the garbage screen we are getting looks like.
Hopefully someone with a little more knowledge can help us out. Thanks in advance!
