icer22x Posted March 8, 2021 Share Posted March 8, 2021 I just did the cap replacement on my sound board and main board. I double and triple checked all polarities and caps. I have NOT done the power board yet. Still waiting on the caps. I decided to test it with a few games. I am still getting white screen and no sound. Could this be because the power board is bad? I really hope so... I was so looking forward to resurrecting this childhood system. Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted March 8, 2021 Share Posted March 8, 2021 Not sure on the specifics of your problem, but one issue I can see is that gold Nichicon 22µf 50v cap you have near the top left will need to be relocated. All the spots on the board where you see those gold circles? Are where the support posts from the back shell press up against the PCB. So you can't have anything in those spots where the gold circles are. Quote Link to comment Share on other sites More sharing options...
