    Blue dots are starting to consume my screen. It started off in the bottom left corner but has gradually infected the entire screen. There is a test on youtube I am going to try. It is under dead pixels.

It is definitely a bad optical block. Sony was offering an optical block replacement under warranty until June of this year, but it has ended now. Ballpark estimate is $700 to $1000 to have the optical block replaced.

The optical block is most likely causing the problem. It will continue to get worse. Sony may help with the repair since they have had a lot of problems over the years with their optical blocks across many models. On the older sets they usually only help with the parts cost. The average repair cost for a optical block replacement is $1200.00 to $1500.00. So if they help with the parts cost it really brings the cost down. Their customer service number is 1800-222-SONY.
I hope this helps,

Lower right corner has green haze


I am not sure what make and model of TV you have, if it is a standard TV then a ground strap holding you CRT imaging tube in pace might need to be deguassed or demagnetised.

green, red, blue blotches on the screen are indications of a magnetic field corrupting the screens electron flow to the image screen.

Blue haze from lower left slowly starting to consume the screen


The blue LCD panel in the light engine is going bad. The only fix is to replace the light engine. This is an extremely expensive repair. However, Sony has extended the warranty on the light engine only on many of these models. Find a local Sony authorized service center and give them your model and serial number to see if yours qualifies for the warranty.
