Receivers and Audio Components

Dear Forum:

I am having an audio problem with a Sony STR-AV240 AM/FM Stereo Receiver. With volume on moderately low-mid output, the sound coming from the speakers and the binaural aspect of my headphones will occassionally stop. But I can still get monaural from my headphones. In order to fix the problem, I have to increase the volume. Sometime, just a small amount, sometimes 3/4 of max. The problem is totally intermitten as is the temporary fix. I have tried to clean the volume control with a tuner cleaner and that helps only marginally.

hey ive got the rca RT2500 home theater system. All of a sudden it just doesnt turn on. The red power button is lit red but just doesnt have anything on the screen. I replaced all the fuses but im wondering what else i can do. Well if anyone has run into this problem the help would be appreciated very much.

I'm new here, I don't know much about fixing electronics at all. All I know is that the cd drawer/tray will not close. It attempts to close, it makes a grinding sound, but it will not close. Anyone know what I can do to fix this? I'm hoping that this is a do-it-yourself type of a problem.

Thanks!
Donna
