Receivers and Audio Components

I have a Panasonic sa-he200 receiver that has worked fine for a couple of years, but is now acting up. It overloads and shuts down after a short period of time. I noticed that the fan does not come on until after it shuts down.Shouldn't it run all the time to keep it cool ? It does this even when it's not in an enclosed cabinet.Do you know of an easy fix ?

Hi, I don't know if anyone can help. I bought a midi sysyem a few years ago, but after about a year, it stopped reading CDs. I thought maybe it was because it had been fairly cheap, so I bought another, more expensive make, but again, after about a year, the CD player packed in. I have used CD cleaners and also tried cleaning the inside but nothing seems to work. I'd like to know if anyone has any ideas I could try. Thanks

Help. I've just hooked my stereo receiver to my home 5 disc CD changer. Once I turn the volume up slightly, while hearing the music play. The receiver will turn off. Please help. Thank you.
