Sounds like the convergence ICs are giving out its a fairly commom problem with all projection TVs. Your model uses two STK392-560 ICs but I would suggest getting a couple of the 4.7 ohm 1/2 watt convergence resistors as most times one or two of them are open as well.You can get new replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can do the repair yourself. Here's the link.

Yellow and blue on the screen and corners are off center


Your TV may have a bad light engine. There are color LCDs in the engine that may have melted over time. The LCD chips would need to be replaced, or the whole engine would need to be replaced. There was a nation-wide repair for Sonys experiencing this problem, so check around with different TV repair shops in your area.

The tv picture looks like should be wachting it whith 3d glasse


This is a very common failure on Projection TV sets. Its called a convergence failure. Here are some common symptoms.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
The other common problem is cloudy lens fluid. After many years the coolant in the blue and green lens will become cloudy and cause the screen to look dull, red/orange, bright white, etc. You may even see halos around objects on the screen.

You can see some example photos and find a solution here on Fixya.

BLUE TINT ON SCREEN ALL THE TIME, COLOR ADJUSTMENTS FINE


Sounds like a bad blue CRT (picture tube) ITs expensive and difficult to replace. CAll a Sony service center for an estimate. but expect to spend $500-700 to replace it.
