Donkey Kong issue

[zds76]

Can anyone give me a clue? Have you seen this and fixed it? If so any suggestions to get it fixed would be greatly appreciated.

Check your voltages and connections .

voltage is good I put my DKjr in and it played fine. I reseated all the chips and cables. I was going to text all the chips against Ident. But dont have a computer set up to check the eproms yet. and wasnt sure if that would even help?

Try this site:

It will give an idea where to poke around.

I'll think about this and do some research for you.

This happened to mine, turned out to be a bad connection from the PSU to the boards. When you check the voltage, check it across the capacitor towards the top, that will give you the (hopefully +5v) voltage on the board. I had problems with both the +5v and the +10v coming in and had to use flux and some heat to clean the connections back down to metal.

Had the similar happen on my Ms Pac and it was the edge connector to the PCB. Cleaned with an eraser and it's been working ever since. No idea if this would apply to a DK though.
