On this set there is a common problem. 1st question ..in the customer setup menu. does the set have the convergence option. if it does not then it could be a special small fuse that tells the tv that it has three tubes. this fuse blows do to bad solder connection. NOt a difficult repair and not costly. If you do have convergence option and the picture is bowing then it will be the convergence power supply which will need to be replaced or repaired

If this is only one color that is affected its possibly one of the 6 convergence amps if its more than one color affected its more than likely the convergence board. You can get help and parts for your set at the following link. Leave them an email with yoiur model number and what the symptoms are.

Shadow effect on picture. Picture is fine but there is a red shadow tint to everything (basically everything is written twice, but not in the same spot)

Red shadowing is really annoying. Can anything be done to fix it?


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....
•Screen looks 3D
•Colors don't line up
•One or more colors can't be adjusted when using the convergence menu.
•Screen is bowed or warped.
•TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

BLURRY SCREEN


If all 3 colors are mis-aligned, you may have solder connections that blew a fuse. There are three fuses next to the flyback transformer, one usually blows causing this issue. Resolder the flyback solder connections and replace the fuse to fix.

Broken TV


you will need a convergence amp board or a convergence power supply board depending on wether its one color out of alignment or all of them. Let me know what color or colors are out of alignment and I can help you out with board selection.
