Blue color in the corners now start to go everyvere on the screen

That sounds to me like weak tubes or low emmission tubes. If it is old, it may be past its best and time for a new one.

This is optic unit (light engine) problem, it has 3 color lcds and blue lcd along with related UV filters became defective and causing blue mark on front screen.
Need to replace optic unit (light engine) to resolve the issue.

do you have any speakers or magnets on top or near the tv.......if so move them away from the tv...thanks

Hello Wealth744:

The problem is that your LCD optics Engine is failing. There are three small screens much like the size of a nono Ipod screen, inside of the optics engine. Each one a different color Red, Green, Blue. The blue lcd screen is faulty.These can be replaced but labor to do this is intensive and most tech will want to just replace the optics engine. So in short the Optics Engine need to be replaced to correct this problem.

It is most likely the tube going out. Find some one to replace the tube if the TV is fairly new other wise it is going to be a trend. One tube now and another.. and so on. Ride it out as long as you can then go for an upgrade

Your optical block is going bad. Contact sony support with your model and serial number. They sometimes warranty these even after the 1yr warranty has expired.

I have had the same problem

This happens from overheating or from physically abusing the screen

I have an acer, which can take a lot of punishment, but i throw it around and keep it on 24/7 until it gets so hot the plastic starts to smell and melt

Awesome computer, it still works very well for the price (500$)

It developed blue lines on the screen lately and i know from previous experience acer will replace your screen as this may be a factory problem

If you're a freak like me who runs his computer all the time though, they aren't going to listen to you for one second and you have to deal with it

A) Dont use your computer as much (that sometimes fixes it)
B) Buy a better cooling deck
C) Dont abuse the screen (any bending or even the slightest tap can kill it)
D) If the problem doesnt go away, make peace with it and get used to it
E) Replace the screen (i dont want to, so now i have kewl blue lines on my screen)
