Question about Sony Audio Players & Recorders
Problem seems to be intermittent. Can turn off the receiver and turn back on after several seconds and the voice level will come back to full volume....then the same problem issue will occur in a few minute.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The problem is IC 451, (Yamaha Part # XU814A00) (Number on part PQ05RD11 Made by Sharp). It's a + 5V 1A Voltage Regulator.
It's located at the bottom of the power supply board mounted to the front heat sink. It's a four legged TO220 Package outline. So don't try to slip a three legged 5 volt regulator in it's place. This can cause serious damage and headaches. Change this part and everything should be good.
