Screen has double vision when showing picture--I tried the convergene button on the remote to adjust the lines blue and green and nothing happen/ I also reset the video to factory setting and my TV is still has double vision. I have a Mitsubishi WT-46809. Please help me are direct me to a repair person in the 75252 zip code area When I turn the TV on, there are double lines (ghost image) on the edges of the screen. I gently tap the speaker portion of the television, which fixes the problem. I think one of the bulbs may be loose. It has been moved a couple of times. The tv is approximately 5 years old.
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 projeciton 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....
Here are some photos of convergence problems.
Here is a quick test....
Using your original remote go-to the settings menu then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.
If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.
Note: If you TV has as flash focus or magic focus button only Double vision on my Mitsubishi 46 inch width scre - 69189a5.pngg the button. If it fails to fix the convergence your need to fix it. See below for a fix
CONVERGENCE SOLUTION
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
