Panasonic tx22lt2 lcd tv white screen no picture

Try going into set up menu and look for a screen degauzing function or try setting the screen temp. to warmer or cooler.

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.

my TV has a half black & half white screen & half of the TV is showing the picture including the normal sound,what can I Do,?

change settings

Just white glow with no pictures or on screen menu? If that is the case, the fuse on the T-CON board on the LCD panel assembly may have blown due to shorted circuits or the 5v or 12vdc is not being fed from the main board due to bad power supply.

Please read my guides and see my pictures to get more details.

Hi, i bought a wii a few days ago and like everybody else mine too was in black and white with a grainy picture. I have a Panasonic lcd flat screen and thought I had connected it corrected, I got somebody out to have a look at it and found out there are some connections on the side of the TV which I hadn't even noticed before, once I put the red white and yellow leads in these and set the TV to AV3 everything is in perfect colour. Hope this works for some of you.

Take care

This not repairable,it a LCD screen have minor pixels cracks in the LCD screen itself,some body hit the LCD Screen with somethings.

What is the make and model of TV. If it is a Panasonic that has different colored spots such as pink, blue etc. Then you need t6o contact Panasonic as this is a memory reset that they have to perform on the LCD driver board. Other brands of LCD projection sets that have spots that appear all over the screen mostly on white back rounds are almost always dust that has settled on the LCD panels. This requires a technician to clean the LCD panels if possible.

the small signal panel needs to be replaced.

take you tv to a factory authorized service center..
