If it is on all input source. the panel is damaged. You need to replace the panel.

    Check out the class action lawsuits for defective Sony TV. Many models over the past 8 years with the same problem. Do some google search about your model and other similar Sony models with the blue spot and blue smudges on the left side of the screen and at the bottom. Sony is giving free TV's and/or greatly reduced prices for a new model. But hurry as many of the classa ction lawsuits have already expired.

I have small blue dots and a yellow shadow in the middle of my screen


The model indicated uses what is called a Optical Light Engine, it is a very expensive part and likely is your problem---not much else will cause this trouble.

Let me know if you have questions.

Having a big yellow spot background in the middle of the picture.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

My Sony Grand Wega LCD TV currently has a large blue spot on the left side of the screen when powered on. I have changed the lamp, but this did not solve the problem. Could this be caused by bad component...


Hi,
I'm afraid, it is problem of optics unit block (light engine), there are 3 LCDs red-green-blue for color picture formation and blue LCD sounds bad, please call local TV tech for fix.
Thanks.

Blue spot on screen


  1. First, look for the source of the problem. Large speakers, especially older ones, are the most common offenders. Notice the position of the blue spot on the screen (left, right, upper, lower, etc.) for an indication of which direction the magnetic field is coming from.
  2. If you think you have determined the source of the magnetic field, try moving the object away from the television screen. If this does not work, continue looking for other potential causes.
  3. f you are unable to determine what is causing the magnetic field, try moving the television. Sometimes magnetic interference can come from a neighbor's equipment, especially in apartments and condos. Moving the television to another part of the room, away from shared walls, may help.
  4. If none of these techniques succeeds in removing or improving the appearance of the blue spot, try to find if their is any demagnetizing coil button available in front of the TV panel , it may be symbol like magnet and a diagonal line on it

I have two small blue spots on my big screen


you cant remove those spots as they are referred to as 'dead pixels'
im guessing your warranty is already finished, so you'll have to get in touch with the manufacturer and they might be able to give you a few names of places that can fix this in your area.
also, unfortunately, the only way you can prevent anymore would be to stop using that tv. :(

TV shadows


Check the proximity of magnetic fields. Large Speakers near the TV for example will cause colour distortion.
