Having problems with your Flat Panel Televisions ?

My vizio p50hdm made a popping sound from the rear. Afterwards, the picture disappeared and tv screen was black (as if the power was off). Then within a minute the picture reappeared but looked real dull with a weird contrast. I disconnected power cord, turned off/on the tv, and the picture remains dull. Tv has been this way for almost a month. In order to repair, I have to pay an estimate of $600, including parts and labor. Please HELP!



Answers :

The z-sustain board is bad. One of the the heat sinks on the board is cool to the touch. These had LG circuit boards and the number on the sticker, on the board, was a good LG part number. The part numbers were 6871QZH044A.

Do a search on the internet with Google, Yahoo, or Ebay with this part number. The board unplugs and the new one plugs back up. Not an advanced technical repair. Unplug the set and take the back off and match the picture on Ebay with the one in your set. And especially match the part numer.

I replaced the lamp in my Panasonic pt52lcx16 about a month ago. I didn't use a Panasonic lamp bulb, I don't know if that makes a difference.. Now the picture is a little dull and every so often it turns off but the green power light stays flashing then t.v. comes back on. How can I fix this?

Our BenQ tv was given to us by a friend because he was having issues with it and didn't want it anymore, so we don't have a user manual. Approximately 10 min after I put the tv on, the screen will go black but the sound remains on. No picture but sound remains. The only way I can get the picture back is to turn the tv off then on again. This will sometimes happen up to 7 times within a 15 min time period and will eventually stay on again after I've been turning the tv on and off, on and off,
