SOURCE: color convergence problem

If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.

SOURCE: ghost on the screen, blue in color

Did you check the six 3.15 amp pico fuses on the D board in line with the resistors and the two 5 amp picos on the G board? Usually one or more of the Picos will blow especially on the G board

Ghosting or distortion on edges of screen


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

We have blue ghosts with brilliant colors


This sounds like the most common thing that fails on projection TV's, regardless of the brand. The convergence circuit has two STK392-110 IC chips mounted on heat sinks to drive the convergence yokes. They typically last anywhere from 5-10 years, then they fail. A more robust part is now available (STK392-150) as a direct drop-in replacement. My shop has installed these IC's in hundreds of projection sets and had fewer than 1% of them come back with repeat failures. Also check the following low-ohm feedback resistors to make sure they did not go out of tolerance:
  • RK42: 2.7
  • RK46: 2.2
  • RK58: 3.9
  • RK52: 3.3
  • RK50: 3.3
  • RK54: 2.2

Hi, you need to replace the convergence IC`s and any burnt resistors in front of the IC`s, common with all big screen rear projection tv`s, if you attempt to do this yourself be sure to get original IC`s or your just wasting your time, and it will take you 2 hours easy, any questions email me back, BMW Rider
