This is my second post. I hope someone can understand this one better.

My 2 board Donkey Kong is completely dead. I get nothing on the screen or sound. The monitor is on and completely white. I verified all the power leads to both boards 12v +5 -5. Where should I start? What parts should I change? I reseated and clean all chips that I can remove. I cannot coin up. All original wiring no edge connector. Upgraded power supply.

Note: When I first power up the cabinet all I get is a jumping sound.


Thanks.

Thanks.

Is the rainbow cable between the 2 boards in place? How's the video cable? Have you removed the inverter board and plugged the video cable directly to the monitor's video header?

How's the video cable? I guess okay.

Thanks
