SOURCE: WS-65809 ERROR CODE 22
look on the center circuit board and you will see two green Pico fuses they look like resistors but they dont have any bands on them . They will have F9A04 and F9A05 on the board next to them. Check with a ohms meter if those fuses are open you will ned new convergence ICs. Thats the first thing to check are those two pico fuses when you get a 22 error on your model.

code stands for loss of vertical. I had one of these if you can check pico fuses, check the ones on the main power board the one with the 2 convergence amps if any of them are blown then most likely the convergence amps have shorted out.

Did you replace the center board with the STK-392-570 chips or the Digital convergence board mounted on it?
98% of the time if you have a convergence problem it is on the center board---the small board on the left under the metal shield box stores and controls the convergence of this set.
WHICH DID YOU REPLACE?
I am here to help----I have fixed hundreds of Mitsubishi sets with convergence troubles.

Testimonial: "Helped narrow down where the problem is."
Try to unplug set and try it again as if the set was unplugged and then the self check done it will be 1,2 which means NO ERROR detected.
Let me know also what the set does?
