The WS-65809 uses two of the STK-392-570 convergence IC's---if convergence is skewed and will not adjust----both chips and any of the protect resistors around them that are bad need to be replaced.
The repair involves getting the middle circuit board out of the set---You can buy a pair of the chips on Ebay for less than 14 dollars plus shipping.
This all depends on if you are handy and know how to solder----each chip has about 18 pins that are soldered in-----I repaired one of these here yesterday for someone---repair takes about one hour.
If you are able to do it yourself you will save a lot of money as most shops charge 300-400 for this type of repair. If you get someone to do it for you make sure they change BOTH chips---
I have had so many people here ask me how do this repair that I have composed start to finish step by step instructions for this set---they tell you everything you will need to do the repair---if you decide you want the instructions let me know and I will post them here for you.
Not everyone can do the repair---
IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW----I am here to help people.

My WS65809 Mitsubishi shuts itself off randomly. When I turn back on sometimes it shuts off immediately, somethimes it stays on just long enough for the picture and volume to come on and other times it stays on for another 4 hours or more. The LED code was 12
