Roseannmace,
Your TV is out of convergance. You'll probably noticed that there are red, green, and blue images. You'll need to determine if the problem is in the power supply or the convergance board. Usually, the convergance amps go bad and opens resistors. Do you know how to read a schematic and use a multimeter? You will also need to know how to remove the old parts and solder the new parts into the circuit board.

Screen, Image, Lines,


Check and replace its LVDS cable [the cable that connects its T'Con board to panel]. Re-seat it once and check, before replace it. Any loose contact with either side of this cable; or the cable itself is damaged, can cause this fault.If you wish to get some details, check the site linked here. Pull up older posts.

My screen is concave and the red blue green colors are all 3 dimensioanl


Go to Menu then setup Look for Convergence if you do not see convergence listed,Then you have a blowed fuse on the Deflection board. It is the bottom board on left hand side it will have the FBT flyback Transfomer and on the Right Side of the FBT is 3 fuses right in a roll they will look lijke small brown retrangler Caps BUT are Fuses 0.6amp. It will be the Middle Fuse.
Partstore.com has them.

Heres another thing you can try with TV off Press and hold Vol- and CH- at same time hold untill TV comes on Now look for Auto Convergence.

My Sony Projection TV middle of the screen curves down on top and curves up on bottom. Picture looks dubble like 3D, screen looks like concaved. Left side of the screen color is light green and blue, right...


This is a very common failure on Projection sets. Its called a convergence problem.
You may have one or more of the following symptoms.
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.
No Audio / No Video - Makes Chirping Sounds

Vizio VX32L image distorts on edges like looking in a metal bowl.


I had a similar issue. Realized that the TV's "WIDE" setting was changed from "Wide" to "Panaramic". It was this panaramic setting that was causing the distortion on both sides of the screen. I had to switch it back to "Wide" using the "Wide" button on the remote to toggle back to "Wide" setting. Once I put it back to "Wide", problem went away. Hope this helps.
