Question about Mitsubishi WS-65869 65" Rear Projection Television
This model uses a single convergence chip---STK-393-110.
If you go into the customer menu and select CONVERGENCE--look to see if red or blue will NOT move in some direction----if so the chip is bad.
The part can be purchased on Ebay for about 12 dollars plus shipping but the real problem is getting at it to replace it---if you are able to do this yourself you can save the set and also a lot of money---most shops will charge 300-400 for this type of repair.
Clearly, I do not know if you have the skill to do this but if you do I can tell you exactly how to do it.
If you do not have the skill (part is soldered in and the center circuit board it is mounted on would have to be removed from the set for this repair) shop around your area---if they say it "has to go to the shop" keep looking as any good tech can do this repair right in your home in about 1 hour-----I know as I have done hundreds of them here and charge 200-250 total for a in home repair like this.
Once the chip has been replaced and the set adjusted you will not have this problem again for 5-8 years----
If you need help or have any questions let me know---I am here to help people.
Regards, SD TECH
