A lens adjustment would help focus for each color only. If the convergence is coming and going, either one or more of the convergence ICs is starting to fail, or there are bad connections that are being effected by heat. Try to see if there is a pattern to when the changes occur. Do they occur more frequently after the set has been on for a while?

Keep us posted. If you can solder, you should be able to resolve this yourself regardless of the cause. If you wish to attempt the repair, please update this and I'll provide more details and instructions. Please try to find a pattern first as that will help to determine the proper resolution.

Thanks,
Dan

    Let's try the simple fix first. Locate the convergence ICs. These will be large black ICs attached to a heatsink. They will be marked STKxxx. Resolder the pins on these ICs. Try the set. That alone may resolve the problem. If not, then replace the ICs using the markings as the part number. These can be purchased from a number of electronics suppliers. I use Tritronicsinc.com frequently.



    Keep us posted on your progress.

How do I reset my Mitsubishi WS-65908


Model number here has 3 hidden menus--adjustment (keep out of that one) and convergence, and OPTION menu.

In the Option menu with the Mitsubishi remote you can do a hard reset of entire set--sets everything back to factory except convergence adjustments.

This requires the Mitsubishi remote and a 4 digit number code.

I am willing to give that but first would like to know WHY you wish to do that as it will not cure all problems like dead set, convergence etc.

Good morning, I am in the moving business and have a customer that wants me to move their large TV Mitsubishi medallion tv. She thinks is comes apart in two peices for easy moving and I need instructions...


If the model is a WS-65809 that sey doesnt come apart. Actually very few rear projection TVs can be seperated Some RCA TVs can be disassembled to several pieces. Also I would let customer know that because a CRT TV has three CRTs that are aligned to each other , Moving the TV will cause the convergence to be adjusted. Based on model it can be just pressing the auto convergence option with the remote, But older rear projection TVs (2003 and older) have been known to blow ICs after a move when trying to reset the convergence. The ICs weaken over age and they can blow anytime the convergence adjustment feature is used, so its always a good thing to let someone know that even if very careful when being moved there set may develop convergence issues after a move because its a 3 CRT rear projection TV

Curved top bottown, now ws 65809 turns off.


Your convergence has failed and need to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed.
You can get the parts and instructions from www.TvRepairKits.com

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.

If this information has helped you, rate this solution as I do this here for FREE.

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.
