LCD TV screen turns blue all the time. Fix?

[volcs0]

We have a 13" LCD TV in the kitchen. I have feeds from our living room Tivo and ReplayTV that go into the video-in on the LCD TV, so we can watch everything from the LR in the kitchen.

At certain times - usually during screen cuts or commercial breaks, the screen turns blue. I have a hunch this is a "feature" of the TV - i.e. the TV thinks it is static and turns blue to prevent a snow static screen. Turning the TV off and then on fixes the problem. But if we replay the same scene cut, it does it again - always at the same spot. It only does it on the video feeds (Tivo and Replay) and not on the direct cable in.

I've searched through the menus, but I cannot find an option to turn off this feature. Our old CRT kitchen TV did not have this problem.

It is a Polaroid LCD TV. Any other ideas (besides getting a new TV)?

First, I'd check all the cable connections to the TV, at both ends. Then check all the cable connections for the TiVo and Replay (if that's not redundant.

If that doesn't fix it, I'd try replacing cables, one at a time. Also it *might* be that the TiVo and Replay have lower output levels than the Cable In, and the longer run of the former sources' cables make the signal a little marginal, and you get the Blue Screen of Annoyance. *Maybe* a better cable might help.

I doubt that there's an On/Off for the "feature". I have a similar feature for my Yamaha surround sound integrated amp. Blue screen when there's no signal. No On/Off there.

For my amp, it might be some way of preventing damage to the monitor/TV which (in its day) would have most likely been a CRT.

In your LCD's case, it's probably to tell you that it's not getting a signal, and I wouldn't imagine there you could defeat that.

You might contact the manufacturer to see if they can help.

How do you split the signal from the video sources?

I am guessing they're still hooked up to the TV/devices in their same room. Do you split the cables with a simple passive splitter or do you use a distribution amp?

It's just a guess, but if the TV has a signal threshold level, and you have the signal split in half (two devices), the cut scenes may be confusing the TV to think there's no signal present.


And idea to try: Undo the split. Run the kitchen TV direct to the video source(s), then playback known scenes which cause the behavior and see if it still persists.

I have all the devices (a Tivo, a replay, an xbox w/ XBMC and a DVD player) running to an AV selector. For each device, I have the digital out going to my receiver/amp for the living room. And the analog sources are going to the AV selector.

From googling (and from above), I suspect that the signal is intermittently just too weak, and the TV is considering is as "no video signal". There are boosters I see on ebay for $20 or so - I might try one of those.

Thanks for the help and the suggestions. I will also try playing around w/ different cables - maybe use one that is shorter (the one there now is ~50 feet).
