Proto Sound 2 5v board repairs

Paul LytleOGR Forum Member

Hello Everyone. Working on Proto 2 5 volt boards. Looking from those that have repair expierence. I have replaced mutiple Capicitors already that charge the battery or BCR. What im looking for now what are the other issues people are seeing? What else is failing? I have a few other boards that all the capicitors test fine on but they still are dead. Someone mentioned bad diodes. They seem to test good as well. I have attached pics of a board i have seperated and numbered. Keep in mind this is an older 5v board and does not have the extra capicitor. I have also numbered top board and bottom board. If you can, please refer to top board or bottom board with the number assigned in the discussion. I am determined to repair them and get them working again. Thanks for all your help!
