Hi folks, I've had my Pioneer 49TX receiver for a couple years. Over the past couple days a couple of time the reciever went silent, sending out no sound signal, but otherwise working (it was on, switching my video signals fine...just no sound). This happened at the end of last night, following a day of pretty much normal use (maybe a tiny bit more use than normal, a few hours). The next morning it worked again. Earlier tonight the sound stopped again (in that it had been off for about 1/2 hour and I turned it on to find no sound). After a few hours I turn it on again and the sound is working again. Any ideas? Does this ring a bell for those who own the 49TX? Gad...I don't wanna have to get this monster outta my rack and send it in. (BTW, I do know of the "shut down" problem people used to have with the 49TX. But I understand that was when trying to drive low ohm speakers at loud volumes. I'm using 8 ohm speakers at very moderate volumes). Many thanks for any insights.
