Hello, I have a lg lcd monitor. w1941s model. when I start my computer, it work for sometime. then it goes blank showing only the LG logo. then the power button doesnot work. it hang up glowing. again


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.
Take it to a repair shop.

The TV doesn't turn on most of the time.


When this happened to us the lamp had burned out so you might try replacing it. After several weeks of waiting for repairs we fixed it in a few minutes.

Hi.. Sorry to hear that the Picture is freezing.. Here are some of the steps that you can try:

* If the issue persists, you need to contact the nearest service center to fix this.

Hdtv picture freeze


I also have a Brand new Sony Bravia 52" LCD with Comcast Cable (motorola box).When switching between HD Channels sometimes the left side of the screen shows a smushed version of the new channel, and the right side is a frozen picture of the previous channel. I correct this by switching to a non HD channel and back. Cable or TV problem I wonder?

Picture freezes on Sony Bravia 46 in


this can be a weak signal check the connections on cables. also in hot weather you can get a build up of static electricity and it will need to be discharged, turn off tv at mains and cross the connector and the cables if you have a buster or other box connected to them turn off and do the same to them. use something metal but make sure there is no power to them.

37" polaroid lcd tv will not turn on


first try to follow the automatic reset method by unplugging all the wires from the electrical outlet whic connects the tv such as the power cord ,the dvd player or any other devices connected to the tv externally .then plug it after sometime and ON the tv. if the tv doesnot work try this. its the problem in the capacitors and the--- ics--- on the main power supply boards.as some of the caoacitors and --ics--- are blowned out or bulged up on the board and not supporting the tv to start normally.so please check the board and get the faulty one replaced and also check for the blowned out fuses on the power supply board.as the blown fuses can also cause this problem.
