I have a Gallag board that doesn't seem to be working. It was working ok for quite a while, but than it started acting up. It started with the score screwing up, than the picture would freeze up every now and than and finally the screen just went white. I tested the voltage at the connection on the board and I set the power supply for both 5.1 & 5.2V, neither seemed to help. I took the board out and cleaned all of the chips and put them back - I believe there were about 15 that I could remove - still nothing. Is there anything else that I could test? Should I try replacing some of the chips? If so, where can I purchase replacements? I really would like to get this thing going, so any help would be greatly appreciated.
 
I got the same problem as you. I also cleaned all the chips, nothing. I just got done doing a cap kit on the monitor. I swapped the monitor over to another game and found out I was having problems with that also, but i do know the power supply is good, and i know the monitor is not the problem either for the game. I am sure the board is bad also I get nothing, no sound, no coin up, no test,etc..
 
Do you have anything on your screen at all? My screen is completely white, but everything was working perfect at one time. I am beginning to think that it is the board on mine as well, but I don't know how to even begin testing it.
