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.

have the same problem, one or more of the flourecent light bulbs in the back panel got broken, looking for a supplier who may keep these bulbs in stock, or other wise will see if i can get a used one off ebay for spares.

This problems could be also causes by the board the call the T-CON docoders board,it sit in at middle of the bottom of the LCD screen panel.Because this board decoders incomming pictture signal before it go into the LCD screen panel to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decoderd board for the replacement.

Ur LCD inverter board is dead.Part and labors about $200-$300 dollars.

If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Call 1-800-Samsung to set up a warranty service call. They will repair it in your home if they send a Samsung Field Engineer. You probably have a bad Main bd.

check if the back lamps are still on when you lose image, all you have to do is get close to the screen and make is totally black and if is not that means you have a back light working, but if the back light is gone you may have a defective panel.

talked to samsung TA about the same problem I had and the recommend to replace the power supply first to confirm a defective panel because a panel is quite expensive

i have taken the tv to repair shop a circut board has went on it
