Question about Televison & Video

We've had a 42"

We've had a 42" LCD/HD plasma for 7 months now but the other day it switched itself of and now there is no picture or sound. There is power going to the tv, we can hear the clicks and see the red Led turn blue but it does not respond to any remote actions or on tv buttons either. it will stay on for around a minute at most then switch itself off as if there was no activity for it to stay on. Ive tried new leads, checked everything is fitted correct, even isolated the tv from cable box etc just to see if the tv would work on its own but nothing. Just a blank screen and no sound. It was purchased from a catologue and the warranty was never activated so im looking for any option that might be possible that wouldn't affect the pocket to much... Any idea's on what i might be able to do? Thanks for your time, Bobbins :) --------------------------------------------------------------------------------------- Chu3505 Rank: Guru Rating: 87.19%, 3597 votes Tries tv unplug,replug it back like about an hour later.Most of the times tv will resetting itself back to the factory setting and will work again.If still have the same problems,tries pushes the power button on/off a couple times for trying to fire up the tv Tuner signal board,these off/on tries work with many LCD/Plasma HD tvs.But this kind of problems,eventually u have to change the tv Tuner signal board sooner or later. Because the tv Tuner signal board it is dying,and this solution is just a temp fixed for the delaying it for awhile. --------------------------------------------------------------------------------------- Hi just realised its been unplugged all night and it is still doing the same thing as before when i just plugged it back in and it didn't come on so tried power button repeatedly but still no joy. Is there a way of resetting it myself like taking the bios battery out of a motherboard?

Sounds like the powersupply is bad. Try replacing that. Hope this helps.

Ten years is two lifetimes for a Plasma, it most likely is either the display panel itself or a main board, in either case not cost effective to repair or smart but the real problem would be parts, I bet almost zero is available for this.

42'' LG Plasma bought in Australia doesn't work in UK?


Find out if Australia uses a different standard of HD programming than Guernsey or not since it's not picking up any channels at all with an attenna. Does the skybox use only scart connections and that's how your small lcd is connected to it?

No video/picture


Solution is to get it fixed (hopefully under warranty).

I have the same issue after owning the Vizio 42" LCD for just 5 months. They are coming to replace the part this week. I will also be purchasing the extended warranty as well, to avoid this problem in the future.

"No Signal" floating notice on Blue Screen - No other picture


If all connections and the tuner have the same issue, you either have a power supply issue or a bad digital board.
