Open Question

My Norcent TV Shuts off on it's own.

My t.v. (R46TV2704S) will shut it's self off after 2-3 hours of use. When the t.v. is about to turn off you see the screen start to become glitchy. The only way i can get the t.v. to work again is to unplug it from the wall for 10-20 minutres and plug it back in. The t.v. will have this porblem if i leave it plugged in regardless of being on or off. For example if i go to bed in the night and turn off my t.v. when i get up in the morning have to unplug it for 20 min before i can watch it again.

Any help would be AWESOME!

    We have a 42 " LG Flat Panel, has worked just fine from January to October.
    It started shutting itself off after a few hours of use, and we also have to uplug ours for awhile to get it to work again. It seems the longer we leave it unplugged, the longer use we get out of it.

    Last week, we took it to a repair shop. They ran it non stop, 24/7 for the entire week, and it never shut itself off.

    They suggested that it could be the fact that we have the tv, the satellite, and the surround sound all plugged into the same strip in the same outlet.

    We now have all three appliances plugged into seperate outlets, and in seperate circuits, but the tv continues to shut itself off again here at home.

Well, first your model number is the 42 inch, but I digress...

I had a similar problem with a Viewsonic 27 inch, with the blinking power light on a failed power-up. It turned out that replacing the power transformer was the ticket. However, as I have the 50 inch Panasonic plasma, I know that the transformer is built into the set itself. I'd still suggest that this is what needs replacing though, as this is different from a set being on but having no picture.

Actually its a panel fault. You will need new inverter board for the panel. (That is if you get the power and sound, but no picture)

I think you are looking at a power board problem. I had the same thing happen to a Vizio and I replaced the power board and it solved the problem. It could also be the input board but most likely the power board.

Green "ON" lights comes on (after some jiggling of the on/off button). Nothing else. Black screen, no sound. Where should I go next?

Tv shuts off and on by itself


I only hope you have connected the tv with a stabilizer or is it inbuilt? This might be because of Voltage fluctutations. Also, check the connectivity of the internal power card.

Tv comes on at 1 am by its self and then shuts off at 6 am? whyy and how I stop it.

1. go into the setting and make sure there is no timer set to come on at this hour. If you do not know how to do this and you need a manual please reply to me and request a manual for this TV.

2. if there is no settings on this hour for you tv to go on and off then there is something abnormal in its power supply that will beed to be fixed.

Problem turning TV on

This may be a faulty power supply or control circuit board. Further diagnosis would have to be done to pinpoint exact problem.
