I have a problem with my Sony receiver, it has an extremely annoying habit of switching itself off. It isn't just a case of overheating, as it can happen after being on for just a few minutes. Sometimes it will go all evening with no problems at all. Usually the first sign of trouble is no response from the remote control and often later followed by switching itself off. Turning it on and off with the power switch or unplugging it from the mains, makes no difference, the receiver will only come back on when it's good and ready. Usually it's back on the next morning in demo mode. The receiver does tend to power off when using DD or DTS and from memory, seems ok when using Pro Logic or in stereo only. The speakers and cabling are fine with no shorts. I recently went back to the dealer where I bought it three years ago. I was told that it was just time to buy a new one and that sound quality on new receivers and amps had improved so much since I had bought the Sony. Is this true? If anyone has any ideas what could be at fault in the receiver, I would be very grateful. I may be able to get the part(s) from Sony and repair it myself, rather than paying a £75 minimum charge to the local repair agent for Sony for just having a look to see if anything could be done. If it could be fixed, there would be parts and labour charge on top and before I know it, I would have a bill for around a couple of hundred pounds or more. I would rather put that towards a new receiver So as I said, I would appreciate any advise that could be offered, even if it is "Buy a new one"! Thanks, Steve.
