could be a few broken or weak solder joints or tracks...try going over them
all with a soldering iron..and check for cracks on the board's PCB

Dear All!
The left channel disappear from time to time on my Yamaha RX-V1
receiver.
The technician from Yam. Serv. Center looked at it and said I need to
change
PSB Board. The repair cost will be $220 US.
Is it looks like true? Is it any way to get it cheaper? I am in NYC
suburb.
Thank you for help and answer.
