This symptom usually indicates CRT failure. Projection TV's, especially older types use 3 CRT "guns" to project the image on the screen. One is Cyan or Red, one is Green and one is Blue. If the Red and Blue become weak or do not project, the Green gun overpowers the output of the other two. These three "guns" are aligned exactly on top of each other so when all three are correctly functioning, the correct colors are projected on the screen.
Your other model was more than likely a CRT projector where you coulod manually align the Red/Green/Blue guns. The one you have now is more than likely an LCD projector which can't be readily aligned. Sounds like the panel is failing.
As in there's blotches of red and green at the edges, but the image is still there?
If so, then your screen may have come into contact with magnets, or maybe the alignments are off (TVs align overlapping images in red, green, and blue).
As always, check with the manufacturer support lines, as they would have specific information for these kinds of scenarios.
These procedures are from the owners manual, go into menu and then picture quality and then:
The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’
images are precisely aligned, they create the color images you see on the screen.
Over time, the picture can drift out of alignment (this is normal). If your picture
seems fuzzy or has a yellow tint, using Convergence could correct this
misalignment. Only one convergence is needed for all inputs, regardless of the
Note: Make sure the TV has been on for at least 30 minutes (TV needs to
warm up for best results) before starting Auto Converge or Red/Blue
When you select the Convergence feature, a submenu appears with three options:
Auto Converge Automatically aligns the projection lenses to self-correct
color images. You’ll see flashing squares of color dance across the screen
(this is normal).
Note: After performing auto convergence, use the Blue Centering and
Red Centering menus to fine tune convergence in the center of the
screen, if necessary.
Blue Centering Aligns the blue and green images to fine-tune the picture.
Red Centering Aligns the red and green images to fine-tune the picture.
Note: The ability to change channels is disabled when adjusting the
convergence options. The TV must be tuned to a usable signal to
converge the picture.
Ur tv convergence are dead.U know how to solders?Must replaced the 2 STK convergence ICS,some or all it resistors.Tries Websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks! See link for more detail http://www.ehow.com/how_4575598_yourself-projection-tv-repair-convergence.html
yes this can be fixed
it is the convergence IC's that controls each color image alignment ,also other components(resistors , diodes , capacitors , ect..) in circuit with these convergence IC's(STK's) also need testing to see what other component has also failed or needs replacing.
