degousse (demagnitize), or your colour drivers and crapping out. Or you may have something magnetic close by. did you just move your set?

My LG rear projection TV RE40NZ60RB colour is ghosting with three colours separating. Colour converging does not rectify


There is a problem with the convergence circuit. It can be as simple as poor solder connections at the pins of the convergence IC or a defective IC. If you can solder, you can fix this yourself. Please confirm the model number of hte set and I'll provide the part numbers etc. required to resolve this.

Thanks,

Red and blue ghosting,


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

I have Samsung $2 W5HP TV (Tear projection). It has started giving 2 ghost lines and colours are not mixed. What can be the reason please? Thanks


This is a convergence problem. If you can solder, locate the convergence ICs and resolder the pins. If that does not resolve the problem, the ICs should be replaced. These are large black ICs attached to a heatsink and may be marked STKxxx.
Keep us posted on your progress.

You will have two of the STK392-110's in the set so a good idea to replace both. The reason is one of the IC's is dedicated to RED horizontal and vertical and then GREEN horizontal, the other is dedicated to the BLUE horizontal and vertical and then the GREEN vertical. These are the best place to start for ghosting in the colors.
