Its power supply related or something is triggering the shutdown circuit because of a problem---for a 26 inch it may or may not be economical to fix.

SOURCE: ILO 32 in lcd keeps turning itself off

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

My 32" Element LCD tv is broken. One night I was watching tv and all teh sudden there was blue, red and yellow lines running horizontally across teh screen, audio was fine. I turned it off and unplugged...


Yes!
It has suffered a breakdown in the power supply and the damage has also spread as far as the sustain boards that control video and convergence. This is not a DIY and the repair for parts is $300 + labour. However, get a few quotes. At least a 32 in is a little more transportable than a 6' model

Please rate my help++++Thanks for using FIXYA

I have a Viore RPT50V24DX/SMS TV, That just turns off after a few minutes. When it's on it's nearly perfect, but then it quits. The cooling fan is running, and there's not much dust inside. Any Ideas?


A: Check clearances for proper ventilation, as overheating can occur even with the fans running. B: If A checks out then replace the lamp as it is in failure mode. They do not usually just all of a sudden fail. They give symptoms such as this.

LCD TV Remote quit working


Hi,
First thing, turn off the TV and unplug it for about 2-3 minutes. Remove also the batteries on your remote. Re-install the batteries on the remote and plug in your TV. Power on your TV using the remote. No luck?
Norcent may not be supported by a universal remote. If you just bought your unit new (maybe Best Buy who carries this brand) you are still covered by its warranty. Below are ways you can reach Norcent.
