One or more of the projectors lights( my guess is the green one) are either blown or in the process of going bad. Have them repaired or replqaced by an authorized tech.

This model uses two convergence IC's----if 3 D one or both are bad.
Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.
Both chips and any bad protection resistors around them need to be replaced and the set adjusted.
If you are able to do the repair yourself total parts cost will be under 30 dollars.
Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.
When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.
After some years the grease dries out from the heat and one of the chips goes instantly.
You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--
If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.
If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.
If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.
IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know
I can tell you what you will need aside from the parts and how to proceed with the fix---
If all this helped rate this solution---I do this here for free.
IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.

Testimonial: "You truly are an expert! Thanks for the advice, don't think it could've been explained any better!"
ok, you have more than 1 post for this set--this model uses two of the STK-392-110 OR 392-150 Convergence chips.
If magic focus will not adjust the picture both chips need to be replaced--about 13 dollars in parts if purchased on Ebay.
Green is not offered to be adjusted since it determines the geometry of the picture--red and blue are adjusted to it.
Let me know how much skill you have and I can tell you how to fix the set--it requires two things--getting at the chips and being able to unsolder and replace them--there may or may not also be some resistors around them that are now bad and need to be replaced.
most shops get 300 or more for this repair--total parts cost if you are able to do it yourself is under 30 dollars.
If this helped you rate this solution as I do this here for free.
