I am guessing that this is an LCD projection set, Please post the make and model so I can confirm. In the mean time, if it is an LCD, there are 2 possiblities.

1) The lamp may require changing. Sometimes the inner surface deteriorates because of the heat.
2) The "light engine" requires replacement as the heat and light have started to burn the LCD surface. This burning starts to show up as a yellowing usually onm one side first and spreading to the other side.

I have read another solution which may indicate the light engine has failed and will likely need replacing. The cost is quite expensive. $1500 range and apparently the part is no longer available from LG. Best you might do is get an estimate to repair just to be sure.

Yellow spot in middle of screen


Hi there,
We have the same exact problem with the same TV. We've only replaced the bulb once about a year ago. Don't know if it had anything to do with the fact that we now have a large yellow circle in the middle of our screen, which is about 7" round.
We only noticed the yellow mark about 4 months ago.
Hopefully someone will have a solution for us that doesn't cost an arm and a leg. Paid $2100 for this set and are a little disappointed.

DEVOLPING YELLOW LINE ON SCREEN


The yellowing of Sony’s KDF-60WF655 rear projection is a problem with the SXRD optical engine. This turned out to be a big problem on many of the SXRD TV's. Sony actually had a class action lawsuit that covered the optical engine for 5 years. My unit was replaced in June of last year (2009) about 1 month before the coverage ended. My unit had a bad yellow streak on the right hand side. Sony no longer covers the cost of replacement, as the class action suit has now expired. Sorry for the bad news. Its not clear if a new optical engine will suffer the same fate after a few years. Sony’s rear projection TV's are amazing and the picture rivals many of today’s LCD's and Plasma's. Any authorized Sony Tv repair shop will no exactly your problem and will be able to give you a fixed price to repair.
Hope this helps

Could be dust around the optical block. Could be that the blue LCD panel is going bad from being heat stressed. The blue panel is closest to the lamp so it gets the brunt of the heat from it. Call Sony and complain. They know about this design flaw and have been replacing light engines even out of warranty on some models.

Yellow area on screen


either burn in or magnetic field interference. I suggest moving any speakers away from the tv. if thats not the case, then find a strong magnet, make sweeping motions across the screen with it but dont touch the screen! Keep doing this until the colors change, then "sweep" them with the magnet into a corner and they will mostly dissapea.......r, sounds complicated but worked for me. can be scary so dont try unless sickly despearate or confident.   Hope This helps!

Your problem is with the blue color,maybe some dirt is sitting on the face of the blue crt and is being projected bigger to the screen,you should try cleaning the face of all 3 tubes,if you familiar with tv service this should help,be careful when removing the back and make sure the set is unplug when you do the cleaning.Let us know how it goes.
