Making progress on my DK cocktail but still need help

In my last thread I had garbage on the screen when the machine was turned on.. This morning I was removing every socketed chip to clean the goop that was covering every one.. I noticed on of the eprom chips was installed backwards. After reinstalling them properly the game now comes up, but after about 5-10 seconds it wigs out.. I made a video of the problem.

Since I did find one of the chips installed backwards is it a good assumption that the eprom chip is now corrupted?

I also don't have the 16v coming out of the PS so I'm crossing my fingers that replacing the capacitors will fix that problem so I can have sound.

Thanks!

Umm it was the third eprom from the left where the group of 5 are and the last socket is empty. I'm at work and don't have the board near me.

The labels on the chips are hard to read, but it is the third one from the left.

That sounds like it's one of the CPU program ROMs. If any one of those ROMs are bad then the game will most definitely not work correctly, if at all. You'll need to check it in a ROM reader and/or have it replaced.
