Ok situation appears to be silly. Coin door lights up and so does button on control stick. The monitor is getting power but no image.so I tried to coin up to see if I could hear game noise. Nothing. I hit a test switch on the board which made a game noise. Can anyone help? Monitor isn't a wells garner is a elect something. Was quick bringing it in so I didn't write much down.
 
maybe an electrohome, when you hit the test button what kind of noise do you get.any neck glow from the monitor?might be two fault with your game . monitor and logic board.
 
Based on this info I might guess that you have a board issue but you really need to test the power supply voltages that go to the board. The PS might have an issue. Coin lights, stick light, marquee and monitor getting power don't really mean that the board has the correct voltages.
 
i had a similar issue with my zaxxon,when powered up everything would be lit but nothing on the screen. when i hit the test button i would get a game noise and the monitor showed a bad ram, thats why i was wondering if you have two problems maybe.
 
ok i do have a dedicated congo bongo. is it true i could swap my board in there to test? does anyone have a pinout or board diagram so i coudl test the power to the board? worse case scenerio does anyone work on these boards?
 
Ok I have two issues. this is based on swapping boards between congo bongo and this game.
congo bongo plays blind which lead be to believe an issue with the monitor. super zaxxon in congo bongo does nothing. no image on screen or anything.

Power to the monitor but no image and i don;t think the tube is kicking on. going to check the fuses on the chassis.
second issue is the board.
so does anyone fix super zaxxon boards on here?
