The tv screen started to go blue on the left corner about a couple of months ago and now the blue has spread accros the screen like a plague! It has consumed 60 to 70 percent of my screen. Is there an inexpensive way for me to take care of this? Thanks.
Me too! Is this a related light engine problem that people are
experiencing with the "red cloud" in the middle of the screen? I just
replaced the lamp, which I thought was the problem, but nope, the blue
is still there. So definitely not the lamp. I don't know what to do?

Sounds like Calibration is needed on the projection internals. Your TV uses a rear-projection system and the problem is either in the imaging LCD Unit or the light filter. I see in a previous thread you have changed the bulb. You can invest in a voltage regulator to keep the hardware in factory condition.
Also you can burn a DVD of a stuck pixel remedy video and run it on the screen with full brightness and full contrast. This is used for plasma burns and stuck pixels on conventional Flat panel TVs but can repair color issues with projection systems. This therapy is focused on the imaging unit between the projector and the main drop of your tv.

The blue LCD panel in the light engine is going bad. Only solution is to replace the light engine. Hitachi was extending the warranty on many of these units. Better check with a local authorized shop. Those light engines are expensive and it is a major labor job.
You will most likely need to replace the panel. You will have to contact Sony and they will send a Factory Trained Technician to your home to replace it. Since you are not on Factory Warranty this repair will cost you. You may find it cheaper just to replace the television.
This sounds classic to a thermo problem where a part(s) are becoming thermo sensitive with aga and use. When the set is cold and then warmed up, the defective part(s) is changing characteristics.
Some components became thermo sensitive that are driving the display. Or an embeded component in the display itself became thermo sensitive. It is very possible that the fault is on the board that does the X - Y addressing or on the backplane electronics of the display screen itself.
Using the set with defective components is a bad idea. If the part(s) fail completely and go shorted or opened, other more costly damage can be done.
The service rep for the manufacture of your set is equiped and trained to be able to troubleshoot and service your set.
You will have to take the set in to have it serviced.
