    Same issue... notice it a lot when watching hockey.



    Heard that Sony will offer low price to new products since optical block is so expensive to fix... I will try when I call, can't hurt.

My brand new LG 37' Led/Lcd t.v. had four very light white spots that you can see in the background what causes this?


Hello
Dead and Stuck Pixels
Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel.
A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background.
A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed.
Hope this helps, if so do rate the solution

The color is all red.


I want you to do a simple visual check of something that will tell me what the problem may be.

Go to a channel that is in black and white--old movie and tell me what color the screen/picture is.

You can also turn the COLOR in the customer menu all the way off and look that way.

What we are trying to see here is if TRACKING is set correctly or has changed. If the screen is somewhat to medium reddish it may be an adjustment outside of the customer menu.

Let me know what you find--I have seen several of these where the black and white picture was somewhat red--the idea is it should be as close to black and white as possible--if red is the predominant background color the picture will look reddish.

If this has helped and you confirm the red instead of black and white picture--I can tell you a easy way to adjust this.

If this information told you something you did not know and helps you rate this solution as I do this here for free.

I just replaced the bulb in my Sony 55'' Grand Wega. the picture looked fantastic the first day. turned on the TV the next day and everything that should have a ''white color'' looked pink. the blues...


Please adjust TINT control of Video Settings in Menu that will adjust color tone of TV. I do not think this problem is related with Lamp because TV screen does not have any color blobs or spots.
Above solution is for Sony KDF-55WF655 model TV, if your model number is different, let me know.
Thanks.

Some black colors are replaced with red blue flickreing in whites


Hi there
Firstly reinstall the graphics drivers, if its still the same there is a problem with the graphics card and you'll have to have it looked at.

Good luck and thanks for using Fixya!
