Need help: video issue over HDMI

[juliusdeane]

I'm posting this here because I think it might be some simple issue that I'm ignorant of.

The last couple months, I've had issues when using my PS3 or upconverting Onkyo DVD player through HDMI on my Westinghouse LCD. They both run through a Denon AVR, but this doesn't seem to affect the issue, because connecting the cables directly to my TV doesn't change the issue.

Usually after watching a source for an hour or so, I start getting a pixelated lack of detail in large blocks of color. (I know that sounds horrible, but I can't describe it any clearer). There's probably a name for this, but I don't know it.

Occasionally, resetting some video settings or restarting the TV fixes the issue, but not always. It seems like the problem is with the TV, but I'm not sure what to do. I'm including a picture of what this looks like up close.

So it does the same thing on your ps3 and dvd player?

And it also does the same thing whether its going through your reciever or not?

Try a different cable, but other than that your TV is the most likely suspect.
Is it still under waranty?

Does your TV have multiple HDMI ports? try another port if so.

I think I tried it before, but I tried the other port again. No change.

All three of my cables are the same cable from MonoPrice.

I'll try to borrow one to test things out, but what are the chances that all three cables are causing problems?

Oh, and I think my warranty just expired a couple months ago. I'll check.
