Is the game playing blind? I think so because when I turned it on I hear the music of the start up. Yes, it's making a hissing noise, I think its the monitor or in that area. Are these the symtoms of a bad flyback? There is nothing on screen. Will do some research on flybacks.
I just got a new game namco ms pac-man galaga. I'm getting no glow from the back of the monitor and its black in the front , also a hissing noise from there. Does the board look compleate.
Just got the galaga working! Got some z80s from mike'sarcade and just added two new ones. Its working great and the kids are having lots of fun. Thanks everybody for the help.
Well decided to take care of the coin light 25 cent one and top light because none were working with new bulbs. So the coin light worked but the top light went out as soon I put on. Then when i restarted it and 25 cent light would not work. Do I need to take off any more parts from here?
I increased the power on the +5 to get 5.3 on the board and got an upside down ram ok and also the background to show. Then restarted it again to have it go back to the same it was.
Well decided to clean the boards and also to clean the pin legs. While taking one off the socket it had a broken leg. Could this be the problem that i'm expericencing. The leg looks like it's still in the socket and how can this be fixed? If so where can I get this part?
Just got this galaga game. I have been working on it for the past couple of days. Got the monitor to work but does not show the game. I checked the powers and it seems fine at 5.o5 on +5 and 11.61 on 12+. Also it seems good on pinout connector and checked on board its reads 5.05. I been reading on here and found that my pinout connector and wire setting does not seem to be the same as the one from galaga pinout from other posts. I'm stuck at rom ok and hear a loud noise. Will try to upload some pics soon.
