SOURCE: I GET WHITE SPOTS ON MY LCD SCREEN

this is a touchy subject for sony. basically sony has increased the brightness levels for the backlights to have better color tones in thier lcd's. well the downfall of this is the white spots you are experiencing. this is not a defect, you will never get them to go away, the only thing you can do is to turn the backlight and brightness down to reduce the white spots. if you contact sony, there is a software upgrade that will help reduce this issue...

Tv problem troubleshooting screen all white no picture


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 aoc 1619sw lcd monitor is white screen only. please help this probleme.


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.

I have samsung LCD tv, my tv seems to have a picture but the screen appears totally white.I have tried with the colour system.contrast....but nothing changed and sound is perfect. thanks


Are you getting just the white glowing screen and no pictures or on screen menu showing? If that is the case, it can be the T-CON board failure or it is not getting the 5v or 12vdc feeding it from the main board.

Why is picture black & white? Sound and picture are good otherwise.


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

My rear projection TV has color spots in the picture, most noticeable on light color picture


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.
