DC jamma

Post by almighty » September 6th, 2008, 6:53 pm

Hope any one can figure out what this problem is,
When i connect my dcjamma to my New Astro, the coin counter starts counthing and when he finish counting there will be no sound.
i can play but no sound?(the led in the psu going on and off constantly when the coin meter counting)

This problem i dont have on my OK BABY but the coin counter there is not working.

i have tried that but stil not working.(led still on and off constantly in psu)
Also tried 1066 in 1 pcb and also the same problem with the led and only when i put my original Killer Instinct board inside it works great.

something is wired wrong in the astro cab,either that or the psu cannot handle the power of the game boards

trace all the wiring to the jamma and check any coin door wiring

I just disconnected the coin counter on the ''parts side'' en connected to the ''solder side'' and guess what, no problems any more.
Hope this will not harm the psu.
