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.

Here are some photos of convergence problems

Sony color rear video projection, Sn 9720391, model KP65WS510. Looks like 3D without glasses. Red double words and pict are shadowy


Common problems with rear screen projections. Either you need to refocus the alignment, or you need to have the Convergence IC's replaced. In your owners manual, it should tell you how to refocus the alignment.

My rca projection tv has blue and green images like a 3D picture would without your 3D glasses, a double vision image and no other colors


sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.

This is a common problem that would require 2 Convergence output IC's to fix . The part # STK392-560 replace with STK 392-570. a repair shop would charge between $200-$300 (parts cost $60.00)

Call a technician to recalibrate your color guns. They usually need to be recalibrated yearly, lately. Many times the cost of getting it service exceeds the value of replacing it with a new one.
