Hello,
I am new to this forum and this is my first post. I was googling and found this forum with experts in Yamaha repairing. i would be thankful if someone could help to fix my receiver. When starting the self diagnostic mode it shows a dc_prt 255H message and shuts down after 5 secods. By checking the service manual downloaded from i found that the voltage at the power amplifier DC voltage is high.
I have removed the cover to check for any burnouts or leakage bu didn't find any. I have all the tools to start checking and repairing but i need some guidance were to start.
Any help would be appreciated!!
