Hey All,
I have a spare Donkey Kong board that I am trying to repair so I can turn it into a D2K (or Double DK/D2K). Anyways, according to this page:
http://www.brasington.org/arcade/tech/dk/
, I have a bad 5A chip (see attached photo). So initially, I swapped out the chip from a spare board. No change. So I finally work up the courage to replace the socket. And I believe I done a pretty fair job at it. I'm sure a professional tech would have done better, but it looks adequate with no raised pads or broken traces and nothing shorted either. So I replace the chip....and I still have the same blasted screen. The game will go through the "garbage screen" at boot up as well as a few game noises. But it always locks up on this screen next. So my question is, does anyone have any other suggestions that might cause this screen shot or lock up. Any help would be appreciated.
