I have a Mitsubishi WS-73907 Diamond Vison and I bought the service manual because I wanted to do the advanced convergence. I used the code Menu 8259 and entered the convergence mode. I was in the coarse convergence on the Green Sd screen and the setting was at 16. I was adjusting it higher to see what chage would be made and the set shut off. Now when I turn the power on it shuts back off in two seconds. I did the error code sequence and I am getting error code 22. Is there a way to get back into the menu or a way to reset to get rid of the change I made? Thank you for any assistance.
