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,PioneerThere is (coloured)'ghosting' - seems to be more - 2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Why is there ghost printing/shadows on my xerox workcentre 7335?


Suresh,
You don't say if the ghost is a particular colour, by ghost I suspect you mean similar to a drop shadow.
Firstly run off an internal test print, one of each colour if the grid lines are fine and showing no signs of shadow then your problem is not an internal problem. Don't send a C,M,Y,K test print from your computer, you can't eliminate colours that way.
If you can pin the problem down to one colour it could be a particular drum unit. Investigate from there.
Good Luck.

Hp 5550 patchy print


Most of the cases fuser assembly or supplies are causes of ghost image. If image is not properly transferring on media causes transfer roller or ETB.
Do this small exercise: Give print command, wait till paper grabs, once paper entered in cartridge area, power it off, open top & front cover, remove paper and see the print quality.Observed any ghost image what you observed? No ghost image? then problem with fuser assembly..

1.Remove fuser assembly, check any toner particles deposited on surface of fuser transfer roller or heater roller.. if found clean carefully with good cotton cloth while fuser having certain temperature,pl avoid metal & sharp objects to clean..
2. Clean paper path roller(You can observe the rollers to push the paper to reach the destination)
I hope this exercise will resolves the issue..

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,
Dan
