I've got a Pioneer Elite system with VSX-95 Receiver/amp and SP-99D Surround Processor. I spent a few hours last night trying to track down and eliminate a very noticable hum to no avail. Here's what I've tried: I removed the satellite cable entirely, I removed every component, one by one until there was nothing connected except the amp and the speakers, I put a cheater on the power plug, I tried plugging it into several different outlets. The hum persists and makes the system unlistenable for television or anything else where there isn't constant sound overriding the hum. I finally just hooked up my TV directly and the system is currently not used. I'm afraid the amp is somehow damaged. I get the same hum on all input selections. Any ideas? Are the Pioneer's prone to this? If the receiver/amp is damaged, is this worth fixing or should I replace? (Wasn't planning on buying a new system this month) Thanks for the help.
