Having problems with your Flat Panel Televisions ?

I have a Philips 42pf7421d/37 lcd tv having problems. When you first turn the tv on it seems to work perfectly fine. About 5 minutes later my picture cuts out and I get a scrambled screen. Turn it off and on, same problem. Any ideas? Hoping I can get this fixed cheaply doing it myself. Im handy but dont know much about televisions. Thanks

Answers :

First, you need to make sure all of the vent panels on the tv are clear of obstructions. Heating may be causing the problems. Next, get a hold of a clean, dry source of forced air and blow out the inside of the case and the internals of the tv.

I have a Samsung HLP 4674w DLP. The picture started to lose color and look like a negative image. Then it would get scrambled and eventually go out. Powering on and off sometimes fixed it, but only temporarily. Sometimes it would also turn off and on by itself. I thought it may be the lamp so I replaced it, but it did not fix the problem. Next I thought it may be the color wheel so I replaced that, but the problem did not go away. Also when this happens the Power switch will not turn the TV off.

You need to change the lamp out, it builds up a internal resistance, and pulls your voltaged down, it will get to the point where you TV will not come on at all. Replace your lamp, you can get one at ... Samsung HLP4674W 46" Rear Projection HDTV

My Sony KDL 46XBR4 when first turned on has vertical lines, or sometimes very dark picture for about half an hour, then the picture clears up fine, as long as I keep the tv on.
