Question about Mitsubishi WS-65907 65" Rear Projection Television
When you click power and green lite comes on for sec and then goes off. I've read other posts on net and done the test to confirm it has the 2-2 Short Protection/Convergence Error. I don't want to spend the money to pay somebody to fix it as the TV is too old and not worth it. But I'd be interested in fixing myself if I can get the parts really cheap and instructions on how to do it. Any suggestions on how to go about doing that?
Change here the two stk-392-570 convergence chips and one of the two pico fuses connected to them, if you still need help I have instructions for this repair in this set--start to finish.

Your problem is not shown on schematic, C9A60 (470 pf @ 1000 v) capacitor and check and see if F9A04 & 05 are open. If so then its off to a whole different area. Do you have an email to send Sch.?

My name is Russ and I will try to help you.
Code 22 generally mean that you have short on deflection board. In 90% cases it cause by convergence amps go bad and than 2 PICO fuses got open (blown) and TV does not work anymore producing code "22". It is very common issue. Convergence amp IC's are attached to big aluminum radiator in the middle PCB and their part number starts with letters"STK". PICO fuses looks like green resistors and they are soldered into the board. Two of them are open as for now.
I would recommend you not to mess with TV (especially if you don't have above average soldering skills). TV is old and everything inside there is very fragile. Professional repair should cost you $250-$300.
If this is too much money for you to spend for repair - just get rid of it and save for new set.
