Question about LG RU-52SZ51D 52" Rear Projection HDTV-Ready Television

1 Answer

Red and blue ghosting,

Hi, our rear projection TV has been great for 6 years. Now it is blury (red & blue ghosting). After convergence there is no difference in quality. I have also noticed that the red crosshairs won't move vertically, only horizontally. when a word appears on the TV, the word appears horizontal (normal) but then a ghosted 'red' word goes above the horizontal word at an angle. general viewing images have red and blue ghosting, a straight line appears curved. Model number PT-53A83T serial number 208KT00117

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,PioneerRed and blue ghosting, - 2_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

Green & Blue Ghosting Convergance problem

Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.

Wavy lines / red ghosting

Sounds like your convergence amps need to be replaced (STKs). I am not sure what the rates are in your area, but typically you're looking at around $200 or so.
