Time Warner Cable broadcast gets stuck in a loop

mwisebaker · 11-01-2009, 07:49 AM

We purchased a Sharp AQUOS LC-40E77UN about a month ago and connected it to our DVR with HDMI cable. Everything went well for a while, and then all of a sudden a strange thing happened.

We had just gotten done watching a recorded show that we had saved, and so we chose the "Delete this show and return to watching TV" option....when it happened, we saw the TV show for a second, then the screen went black, then it went green like it was adjusting the signal, then we saw the broadcast again for a second...then it kept repeating.

We changed the TV to use the input from our standard-def DVD player (which uses composite video) and it was fine....switched back to the HDMI input and it was still stuck in that loop.

To get out of it, we had to navigate to a saved show (which is hard to do when the screen only appears for about a second at a time) and start something playing. Then we could stop it and go back to watching regular TV and things worked fine.

That happened 3 or 4 times in two weeks, at seemingly random intervals. It didn't happen EVERY time we had returned from a saved show to regular TV but that seemed to be the only common thing.

We switched from using the HDMI cable to the same composite video that the DVD player uses (there were only a few options we could easily get to on the side)....it's been connected that way for two weeks and it hasn't been a problem.

So it's either the HDMI cable itself or our cable box's HDMI output.....but I'm not sure how to tell which is which and what I might be able to do to fix it. Any help or suggestions would be appreciated.

Do you have a different unit (blu ray player) to hook up to the same hdmi cable and tv input? This sounds like the dvr is acting up but to eliminate the outside chance that it is your tv or cable,,,try another device.

We do not, unfortunately. The only HD device we have right now is our DVR.

I'm pretty sure it's not the TV itself...I called Sharp and the tech said that the signals from all inputs eventually get processed through the same display engine, so he would have expected problems trying to use the DVD composite video input, which we didn't have.

What are the odds of having a "bad" HDMI cable? We bought it new the same day we got the TV, which was 09/23.
