    I had the same problem......I just called Sony support at 1-800-222-7669 and was able to get them to fix the issue even though the limited warranty had expired....they had offered me 2 options...1) get it fixed or 2) buy a new tv at about 1/2 price...$2500 for $1300 or $2000 for $1000.....I went with just the fix

Sony has extended the warranty for this problem until December 2008, so act quickly to get it repaired. You can find information on getting service here:

Problem with sony 60" rear projection TV


Hi,
I'm afraid, it is problem of optical block unit (light engine) that produce picture by 3 lcds inbuilt, the blue lcd and its related uv filters become defective and causing this kind of blue hue on screen.
Complete optical unit block (light engine) will be replaced by qualified tech to get tv fixed, light engine is costly part so ask an estimate before sending tv in.
Thanks.

What do i need to fix this "blue Blob" so everyone is calling it. it looks like my screen is broke but i know better


You would need an Optical Block
SONY P/N A-1084-660-A
LIST PRICE $ 552.39
CORE CHARGE $1,060.00
(I'd be really sure to return that old one to get that core chrg back)

OR
(very complicated)
You would need to know how to dissasemble a sony lcd optical block (and put it back together).

AND

Obtain the correct polarization filter for the blue optical path.

IF

There is no damage to the blue LCD panel yet(one symtom is blue dots like stars in the pic).

Blue dots and streaks


Blue streaks might have been just your video connection and problem with signaling. But, blue dots is faulty light engine, aka "optical block". The engine in this could be a defective LCD array. Very expensive, a optical block is about $850. Hope it's still under warranty. You could get a rebuilt one, possibly. Need service adjustment too. Bad problem that Sony has with these kinds of sets.

If it looks like a "star field" blue with white specks it is the light engine. Sony has extened the warranty on may of theses sets call an authorized sony service center and see if the optical block i still in waranty. I would to this asap as most of these extended waranties are running out!

This model also has a paper filter for the Optic block that should be changed. No one ever said anything about it. shortens the life of the optic block if not changed.

Blue haze in picture


Sorry guys the news is not good. The Optics or light engine must be changed or rebuilt. The lamp has destroyed a filter (glass element) inside. You must remove the optics and send it out to be rebuilt. Not a do it yourself type repair.

Blue streak at bottem of screen


Hello,

You have the classic "blue blobs," In most of Sony's rear projection LCD's, the Optical block is bad. Manufacturer's defect. The blue panel inside of the optical block starts de-laminating (due to heat from the lamp). This is a very common problem. I have changed about 70-80 optical blocks myself over the course of about 4 years.

There is no other fix but to replace the optical block. Unfortunately, it will get worse, and will probably develop "stars," or stuck pixels, as well. You can call Sony and try to get some assistance, but the extended warranty on these sets has recently expired.

Hope this helps you in some way...
