Question about Projection Televisions

4 Answers

We have a Phillips plasma tv and the picture pixelates randomly and freezes for about a second and sound breaks also. We have had everything checked and have been unable to find a solution. The latest internet research has led us to think it may be the coax. Can you help?

A weak signal can also cause this problem. Better have a tech to figure out or try another antenna installation.

In my openion, Its problem of hardware in your TV and signal processing circuits are involved. It might be problem of Firmware (programe to control the performence over all) Philips can advise you better in this regard.

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

if you take the back cover off the tv, you will see in a white screw in almost every board, those are called pot. (potentiometer).
if you can get to meter the Ve. Vs. and Vset. start to screw or unscrew those white screw according to what the label says.
usually the ones who gives you the blue and red dots are the white screw on the right of the center panel, and the one on the right of the right panel right under the metal thing to hang on the wall.
