Rear Projection - Color convergence/bowtie effect


Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and also check the power resistor, if values are not exact you have to replace them. These ICs are located behind the black heat sink; you can see once you open the back off the TV. Also, the convergence board should be checked for cracked solder joints and please make sure to check the resistors as if they are shot the ICs might blow again. All this is only recommended if you have electrical expertise and know how to solder/re-solder components, if not then you should get this done by a professional. The typical cost to get this fixed by a pro is around $250-$300. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

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

3d image/sinking effect


This is a convergence problem. Ther are either bad connections at the convergence ICs or the ICs are defective. If you can solder, you can repair this yourself. Try resoldering the pins on the ICs first. If that fails to resolve the problem, replace the ICs. These ICs are large, black and attached to a heat sink. They should be marked STKxxx. Figure on $20 for each one. There will be 2 of them.
Keep us posted.
