I've got an Onkyo A/V receiver that's just over five years old. Never had any issues. Lately when I try to watch DirecTV it just shuts off randomly - sometimes immediately, sometimes after a few minutes. But it always shut itself off. After much trial and error and lots of reading online, the best I could come up with was that there was some sort of circuit/power problem which would require repairs.
Then I somehow figured out that the problem appeared to be confined only to the channel I had programmed for DirecTV (VIDEO1). When I used VIDEO1, it would shut down. So I adjusted the settings so DirecTV went through VIDEO3. Now it works.
So my question is, is it typical that just one channel would stop working like that? Is the whole receiver about to crap out or is there something I can do? Anything else I should be looking for?
I'm not a pro by any means, but I'm guessing some wiring went bad with that input and it's causing your receiver to trigger it's auto-shut off function to protect your speakers or the receiver itself from blowing.
I recently had to upgrade receivers because the receiver I had before didn't have enough power to really get my speakers loud, and whenever I would turn it up too loud the receiver would auto shut down. So that's my guess to what was going on with your receiver.
You'll be fine on the other channel for a while, but yes, it is slowly dying. You have a diode that is nearly fried on Video1 channel. The diode for V3 will eventually go. It could be months, but it will go.
