I just want to get an explanation here. A while ago my JVC RX-6010VBK HT receiver started having problems with the front buttons...all of them. First of all it's not a problem since it's still under warranty so I'll be taking it in, but I just want to understand what's happening. Every time I push any of the buttons on the font of the receiver, the front display goes nuts, jumping all over the place. Even turning the power on and off cycles very quickly with multiple clicks (so I don't use it not wanting to destroy it). I have to hit the desired button(s) multiple times to get the right selection. The remote works perfectly. The store I bought it from (Bleeker Stereo & TV here in Ottawa) says it's probably a Ground Fault on the Main Board. It started happening about 9 months after I bought it. The receiver works perfectly otherwise. It's not much of a problem since I never touch the speaker setup anymore (I have it the way I want it) but if I hit, for instance, the headphone button, I get the speaker setup or when I hit the button for FM I get DVD! Good thing the remote works OK. Is this indeed a Ground Fault problem or something else? I have it plugged into a good surge protector and can't figure out why this started to happen. Thanks.
