This is is some resistors on the conversion IC or IC's that control the color alignment
these big chips should also be replaced , they are on big heat sinks and the chips indentification will be on them they start with STK followed by numbers , you can get these from an electronic parts supplier store , but make sure you get all bad resistors replaced and change any electrolitic capacitors that don't look good
here is an example and also might be your chips

Image problem with WS-65809 65" Mitsubishi Projection TV


WS-65809?, if convergence is skewed and comes and goes, uses two of the STK-392-570 CONVERGENCE IC chips.

I have seen a lot of the Mitsubishi sets that use these two chips where the convergence jumps in and out. You need to replace both chips and adjust the set.

You can buy a pair of the chips on EBAY for less than 13 dollars plus shipping.

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THE SETS THAT USE THESE TWO CHIPS.

If you or someone you know can do the repair you can save the set and a lot of money--most shops are going to get at least 300 for this kind of repair--I know as I have done hundreds of them here.

The instructions tell you everything you will need and how to do the repair. I have helped many people here do this based on my instructions.

If you want the instructions let me know and I will either post them here or send them to you.

Turns of after being watched for several hours.


Do you have the tools required to solder electronics? Do you know how to solder electronics? Have you been trained in CRT safty ? Do you know about High Voltage safty? Is the tv Model number WS-65809? Do you know how to perform static geometry adjustement on a WS65809 if needed? Do you know how to perform static convergence alignment on a WS-65809? Do you know how to perform fine convergence adjustement to a WS-65809?

IF
The answer is :yes yes yes yes yes yes yes yes
AND
You can retreive an error code of 23 or 24 right after the tv shuts
itself off .
THEN
There is a 95% chance that I could tell you what to solder , no parts need to be replaced in your television and you would not have to pay someone to repair it.

loose connection.
check for any over heated areas and resolder them specially the convergence IC.This resistor is located in the back edge of the chassis in the board in the right side and it might be hidden by a plastic casing that covers the high voltage transformer.If you are not too familiar with tv service you should seek the help of a servicer.Let Us know how it goes or if you need more information.
