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.

Mine is doing the same thing. I talked with a local repair guy over the phone and he says that (obviously) something is malfunctioning in the TV and a sensor shuts it off to minimize the damage to other components. This would be ok if the TV were 20 years old (they used to last that long); however, mine is only 1 1/2 years old and Emerson couldn't give a damn that the TV is a piece of ****. Silly Mimi
