I have a 1 1/2 year old Panasonic TC-P42U1 plasma tv. While watching a show, it suddenly shut off and won't come back on. What do you think caused this and how can i fix it? Thanks.


Try unplugging it completely for 30 seconds to 1 minute. Plug it back in. If it still won't come on, it's likely taken a power surge and popped a fuse or power supply, which means a trip to the service center.

K957ws500 stays on for about 30 minutes then the screen shuts off the light blinks on the display


You have a bad convergence board, or the TV processor has garbage in ti, and if you leave the TV unplugged from the wall, for 40 MIN. that will reset it back to normal. If that don;t work then it is the convergence board, unless if it turns real blue, or green before shutting down, then that color , the screen voltage needs turn down, then it will stay on. Or the red, blue, or green CRT is sorting out, then it is time to buy a new LCD, if it is a bad CRT. for a service call it will run around 70 dollars to find out. Take care.

Screen freezes and then shuts off. This cycles every 1-2 minutes


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

Try the main board with the cpu chip. The cpu chip should have a heatsink attached to it, may be an overheating problem. It has the LCD panel connector plugged into it. You may be able to find the board on ebay for less than a repair shop.

The digital tuner on my Olevia LT37HVS LCD TV freezes sometimes. When it does, you can't change channels, adjust the volume or even shut it off short of unplugging it. All of the other A/V inputs work just...


Tune the tv to a channel that is just blue screen. Then turn the tv off and unplug for at least 30 sec. Then plug the tv back in and turn it on. Then leave the tv on the blank screen channel go into the menu and do auto cable channel search. After the search is complete try all channels. This worked for me. My tv will not scan if the tv is on a channel that comes in. GOOD LUCK these tv's are junk .
