LG RT39NZ40RB picture ghosting

My 105 cm rear projection TV is almost 5y/o . Has been very good until there appeared a purple/ green half rainbow over bottom quarter of screen and green ghosting of the picture. When text is displayed ( via the remote functions) it is a double image - green and purple - and seems to distort in shape the closer it is to the edge of the screen.

The set has not been bumped/dropped or moved, just suddenly began.

Will it be worth repairing?? Thanks Brett.

Blue ghosting on LG rear projection TV- not fixed by using Auto Convergence button. Any other suggestions - Model RT39NZ40RB


Probably a failure in the convergence output circuit. Most circuits are comprised of a 2 IC package and I would recommend replacing both. $100-150 in parts and some experience with a soldering iron is good. Thx

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

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Sounds like your convergence is off. Go into your menu and try setting your convergence. If you can not move any of the colors you need to have your convergecnce amplifers replaced

LG DLP Projection TV Green/Brouwn vertical Bar


Hi there.

The excessive heat from your lamp has burned one or 2 polarizing lenses.
To replace this you have to pull the optic engine out of the unit and dismantle it.
You will see 3 square lenses in there, remove one by one until you find the burned one.
Then go to ebay and type in hoya polarizing lense.
Buy the 72mm one and cut it to size.

hope this helps.
