Question about Televison & Video
Go to the Zenith repair site. This has been resolved in a lawsuit. Zenith will fix it free of charge through 7/1/2010. The shop just picked my up to replace the light engine free of charge. Call 1-800-228-1757, have your model number and serial number, and where you purchased it. Here's the neat thing-the question I asked is "have they fixed the problem with the light engine, or is it going to keep going bad?" If happens again (blue lines/spots) before 7/1/2010, they'll replace the TV with a new and different TV of equal value!

Please press the WIDE button on the remote repeatedly to remote the Bands. If the issue persists, you may need to change the Aspect ratio to 4:3 on the Video source that you have connected to the TV. Check the link for more info:

It sounds like a convergence problem--If you go into the customer menu and select convergence--if colors are bowed and or will not adjust:
The two STK-392-560 CONVERGENCE IC's that this set uses need to be replaced--their location numbers are IC8001 & IC8002.
They are located on two metal heat sinks with fins--and are black in color--2 1/2 inches wide by 1 1/2 inches tall and will have the full STK number printed on them in white.
Usually just both chips need to be replaced but there are some special fuses and resistors that protect them. A pair of the chips can be purchased on Ebay for about 12 dollars plus shipping.
The chips fail because a white grease to transfer heat from the metal back of each chip to the heat sink dries out and one or both overheat and fail.
If you or someone you know can do this repair you can save the set and a lot of money---most shops are going to get 300 or more for this type of repair.
These sets are dependable and other than this do not have many serious problems.
If you get someone to do the repair make sure BOTH chips are replaced or you will have the same problem again in a few months---lifespan of these parts is 5-8 years.

SOURCE: my tv has a color
TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
