Hey guys...new to the forum. Thanks for any help.
So I have a Yamaha receiver. Can't remember the model number. I can check when I get home. Its about 25 years old. My dad had bought it brand new. Worked great up until about a month ago.
Sometimes when I turn it on the right and left channel will be the same volume (low volume) then all the sudden the right channel will blast almost as loud as it can go. It will randomly go back down to the same volume as the left then go way back up again. It is completely random. I have had to turn the balance almost all the way to the left to prevent it from just blasting on its own. When it is blasting loud from the right channel, if you try to turn the volume up, it has pretty much no effect on the right channel (as it is almost as loud as it can go) but will turn the left channel up. Other times when I turn it on, the right channel is already blasting loud and the left channel can barely be heard. The right channel may go back down to the regular level only to go back up to blasting. I can't figure out what is going on.
I have taken it apart and blown compressed air all around the inside. Any idea what this might could be?
Thanks so much for any help!
