Question about Projection Televisions
Hi, I have a 65" Mitsubishi rear projection TV. Ever since we bought it, the screen sometimes changed into solid pink/purple, but usually it fixed by itself after a while, from a few minutes to several hours. It just changed into pink again a few weeks ago and hasn't changed back yet. The picture-in-picture works just fine, but the main screen doesn't have any picture from tv or dvd or video game....
Thank you very much for any help.
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 model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.
Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.
Let me know what error code is found and I will tell you what it means.
