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.

Sorry that I have not gotten back sooner, have been out of town. Tried your solution worked for one day. Now what happens we have to turn off the power for 10 minutes then turn back on. Sometimes it works...

I'm sorry to tell you this, but I believe you will need to contact a repair shop. Is the TV still under warranty? Either way, contact Panasonic and select an authorized repair shop. 1-800-211-PANA

I have an Emerson TV Model #LC320EM9B about 1

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

TV only stays on for a minute. Screen goes blank for about 2 minutes. Then the picture pops back up on the TV. Model number is KDF-E55A20. Sony Wega HDTV. Made in 08/2006. Please advise....

I think TV on for minute or so, goes to standby and again power up, show picture for minute and again standby.
If above are symptoms then its time to replace lamp in TV.

Let me know if symptoms are different.

TV screen goes blank but power stays on

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
