Onkyo Dr-S2.2 Turns itself ON and OFF

[captainjack0000]

I recently acquired an Insignia� 32" Class / 1080p / 60Hz / LCD HDTV (Model: NS-L322Q-10A) and connected it to my rather old but trusty DVD Player/Receiver (Onkyo DR-S2.2). After 3 weeks of normal operation of the TV my Onkyo started turning itself on and off, at random, but always to the TV/Line setting.

I took out batteries from both remote controls - same issue

I put aluminum foil over the eye of the TV, then later the eye of the DVD player - same issue

The only time the DVD player does not turn itself on and off is when either
A. The television has no power.
B. The television is not connected to the TV - it is connected via S-video, as was the case with the old JVC TV
C. The DVD player has no power (obviously)

The TV is integral to the malfunction, but I suspect the issue is with the DVD player itself. It is almost 8 years old while the TV is less than 3 months (at least from date of purchase).

Any thoughts? For now, we unplug the DVD player until we want to use it.

The DVD player is connected to some speakers, though the center channel does not work and hasn't for some time. My computer, via RCA cable, is connected to the DVD receiver such that music from the computer can be played on the what speakers still work.

If the DVD player is beyond repair, no problem, I'm going to end up buying a Blu-Ray player. I am still curious as to the cause of the problem, and hope that the TV is not the root source. It was purchased as returned item sale and is not able to be returned again. It is a risk, I am now very much aware. it was sold to me under the pretnses of being fully normal in operation.

Also, Insignia's Tech support, and both the 1-800 and local Best Buy's phone support had neither heard of the problem, nor had any sort of idea as to why. The only information told to me was that TV's generally do not send signals, instead they receive them.

Please help quell my curiosity and maybe even offer a fix for my posessed DVD player.

THANK YOU

Update:

I had a friend tell me it could be a short in my S-video cable, or a short in the S-video jack could cause the problem. He suspected it would be on the TV because I did not have any problems unless it was plugged into the TV. I have since bought a new S-video cable and tried all configurations only to find it was not the S-video cable. So the only thing I can deduce now is there might be a short in the S-video jack on the TV or player. Any and all thoughts are welcome.

I've since bought a Blu-ray player to replace it, so its not an inconvience anymore, but I am still curious as to why any device would turn itself on and off.
