Hi, I recently purchased a Punisher botleag board identical to this. Mine has a buton soldered that enables Test menu when pressed.
My board player one controls didnt work. I purchased the board knowing that and hopping to find a way to repair it myself some day. I would apreciate if someone point me in the right direction. Thank you in advance!
Probably the board was powered with the jamma harness upside down, a common failure. In this way 12V VCC was fed in the players controllers pins blowing up the related ICs.
If i’m not wrong, you should check for damaged buffers 74LS245, near the JAMMA edge connector.
Follow the traces from the Player1 controls on the connector to the ICs.
I have this board no more, so i looked at my memories 🙂
Let me Know.
Thank you! I will check ASAP and tell you.
Thanks again for your help!
