Your problem is due to intermittent power in the backlighting circuit. This is usually caused by swelling of electrolytic capacitors in the power board. If you can find an honest electronics technician it is about a $40.00 fix.

SOURCE: Grundig GU22 DVDP LCD TV. No image on screen.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

42hl167 no picture but has sound


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.

Hello,

Your monitor problem is causes by the power supply. What is happening is the power supply voltages are not stable, just enough to power the unit up. When you connect it to a video signal the power demands slightly increase and the power supply can't handle it. This is a very common problem with LCD after a few years of use. The issue with the power supply is the capacitors have started to fail. These parts are used to filter the output voltage and when they start to fail the outputs start rippling hence the problem you are having. Here is a link to a repair article that shows how to repair the Gateway FPD1975W monitor.

The image is made up of three polarisers, one tends to fail causing a problem with the image. On average it may cost £300 per polariser to be fixed. As you know these days you can get a projector for that price as everyone now wants HD and 3D. I recently bought 7x NEC NP115 for just over £200 each. Very good spec, auto power up (Which was important for what I needed)

hope that helps

LCD TV PICTURE HAS GONE OFF BUT NOT SOUND?


If you've tried the backlight and brightness from the menu, you may have a more serious problem.
Try this;
Take a bright flashlight and place it against the LCD screen. See if you can see an image around the edge of the flashlight. If you see an image, you probably have one of three problems;
1) The inverter board is bad.
2) CCFT (cold cathode fluorescent light(s)) are dead
3) Power supply to inverter board is bad.
