I have a Yamaha YPG-635 that will not make any sound either thru the headphones or the speakers, I'm thinking that the amplifier/power PCB is no good. I've tried to go thru and reset all the menu settings as well. Does anyone have recommendations on what I can troubleshoot on the board?
Also, if there is a better place to post this related to circuit repair please let me know. Thanks!
Here are a few photos of the board. I can pull it and get a photo of the traces tomorrow.
