I never like to give people bad news but here is what is wrong:

This set uses an optical light engine---lamp is the light source and shines into the engine through a series of lens and baffles---blue part is closest to the lamp----

A discoloration of blue across any area of the screen means the optical engine has been damaged by heat---damage is permanent and may get worse the longer the set is used.

I would suggest you contact SONY as they did have for this model and some others an extended warranty even if the set is not currently covered under warranty.

If you give me the precise complete model number I can usually get you a part number for the engine and a price---most are at least 600 wholesale and some are more---not counting major labor to replace the unit. All the engines are sold on an exchange basis as they rebuild them for this kind of problem---the replacements are not supposed to have this kind of trouble.

Again, I am sorry to give you bad news but I have seen over 20 of these sets with this type of problem--no adjustment or do it yourself repair will cure this problem.

Let me know if you have questions or need advice--I am here to help.

Your blue LCD panel is failing. It is within the Optical Block and the entire block must be replaced in order to repair this. Over time (usually a short amount of time) this problem while progress until the picture is bad enough that you will want it fix immediately.

4 year old 60inch sony flat screen purchased in 2005


sounds like heat got to the optical block, there are some websites that can give you prices on rebuilt opt units, but i suggest that you take a look at the sony website and check the factory recall section to see if there are any re-calls on your particular model. These optical units are kind of expensive.

3LCD Projection TV 2.5 years old displaying blue hue/blobs


I would first try a new lamp. If the reflector portion of the lamp has any defects, it could show up this way as the light would not be uniform. The next possibility is a defective light engine. The engine portion if not field repairable and would need to be replaced. Try the lamp first and let us know what happens.
