Color changed suddenly, no red, just green/yellow/blue


Sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel.

No blue color, green replaced blue, white is yellow/green


Hello,

If the set is hooked up using Component cables (red, green, blue), then check to make sure the cables are hooked up correctly, and not defective (change them out). If the color problem remains, then the problem may be in the Optics block of the television (which is not unheard of in this unit).

If the menu of the TV displays blotchy discoloration, and the discoloring is the same for every input on the tv (stationary), then it is the Optics, and the optics need to be changed. It is not the easiest job in the world, and the block itself is quite expensive, although the unit my be under an extended warranty from Sony. Contact them directly to see if you can get any help (cost or service-wise). Hope this helps...

Here are the settings:

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Color fades when wathcing TV from greens to reds and also get dark.


Typical problems with lcds.. When they get hot, the color tends to shift. The reason your seeing the problem on the red and green is because of a lack of blue.. Makes sence if you think about it as blue is the hottest wave of light, so the blue panal is getting too hot or possibly the polarizing filter on the tv..

Lamps can cause this somtimes as they tend to shift twords the higher waves at the end of there life.. So if you have another lamp, try it out.

Another possible cause is the driver board for the lcds.. If there is a chip that has a small short, it will overheat as well and cause it not to function properly. I see this all the time on lcd projectors. 1 of 3 things.
