Color allignment on a Mitsubishi WT-42311 42in Rear Projection


You will need to replace the two stk-392-110 convergence chips this model uses. This can be a do it your self job if you have some skills.

This model has a light box which contains 98% of the set's inner parts. With it removed the chips will be easy to locate.

Total parts cost on EBAY should be under thirty dollars and repair should take about a hour or so.

YOU will need to be able to solder as the chips have 18 pins each.

If you think you can do it I can tell you how to get the light box out and proceed with the repair; this model has very few problems and a good picture.


You will also need to have the Mitsubishi remote to correctly adjust after the fix.

Let me know what you want to do--I am here to help.

Projector allignment


THIS IS A DIGITAL CONVERGENCE TV. FIRST IF YOU CANT ADJUST YOUR CROSS IN CENTER YOU PROBABLY HAVE A DEFECTIVE CONVERGENCE IC
IF YOU CAN THEN THE SERVICE MENU PROCEDURE TO CORRECT GEOMETRY IS COMPLICATED AND TIME CONSUMING. YOU WILL ALSO NEED THE ORIGINAL REMOTE AND THE SECRET ACCESS CODE FOR THAT SET

I am getting a double image on my 48 inch television how can i get rid of it? it is showing colors green and red on double image


Assuming that your TV is a rear-projection TV, then it sounds like the separate red, green & blue tubes aren't set correctly.

Each tube needs to be alligned exactly to produce the image on the screen. If any of the 3 are mis-alligned then the effect you describe is caused.

Somewhere in the menu settings, will be an option to set the Convergence. This option will allow you to set the allignment of all three tubes.

Older sets do not have this option, and need to be adjusted via controls on the main PCB.

Blue converence was intermitten now out on sides


If the IC's say have STK printed on them, then they are the convergence IC' s. should be three of them, replace all 3 , and the burned green coils, sometimes these burn as they supply the volts to the STK's. good luck, be safe..

Converence


green is fixed so you have to move red and blue to green.
by using the remote you may find a simple converge function and open this and using arrow keys move the blue or red first to center of screen, repeat for other color you should see the lines moving toward a a white center point.

if the lines do not move with remote try manual ...menu on the set. if still no movement you have a problem on the convergence board and need a tech to fix.

A service manual will explain complex convergence to the detail .
but this might take hours to get it right.
