    This television stays on for about a minute - dims then just shuts down onto standby for no apparent reason. I have taken it away from the remote as I thought the sleep button might be stuck but it made no difference

Panasonic viera 50px80u tv will turn on but no picture. HELP?!?!


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Your TV is 7 years old, so it is not worth spending a lot of money fixing. You could take it to a shop for an estimate.

8 month old Symphonic 20 inch lcd tv turns off itself every 3-5 seconds


these sets that shut down or turn themselves off after a few seconds usally have a bad backlite board in them. look closely at the screen and see if one section looks darker than the rest of the screen (top middle or bottom - top seems most common in my cases). some times if you put the tv on an unused input you can see the variation of light level on the screen, but don't get confussed by looking at the screen from too great of an angle. thanks ......techman 580-243-8025
