The tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all it resistors are dead too.These parts on the tv convergence board,must be replaced to solved pictures convergence problems.The shop,will cost u like $300-$350 for parts and labors.

do not play with this tv replace the stk ic chips and the resistors around the stk chips ,cant miss em about 2 inches big with heat sinks on them.

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.






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 try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Then it is likely the pre-amp transistor that controls the red is shorted out.
hopefully you have extended warranty.
there is a trick to likely get them aligned anyway if this is a tube tv.

When you say no picture, is there any sound or noise coming from rear of set when you try to turn on. If so then you have no high voltage and maybe a cap in the HV line that is bad. If no sound at all, then maybe a fuse or open resistor in powersupply.

sounds like your crt tubes...meaning Red, Green and Blue are out of alignment...or possibly 1 of the crt's is burned out.
