Model indicated has 3 hidden menus---all accessed with the Original remote and a 4 digit code.
At your own risk:
This is a V17 chassis that was used in 8 models.
It has 3 hidden tech menus: With set on:
Option menu is 8270 enter---The Option menu reset will return all settings to factory and also will clear any glitches out of the way--it as stated can cause Convergence not to be affected.
Circuit adjust menu: (stay out as one wrong move and fatal things can happen is : 8257 enter.
Convergence adjust menu: (better than customer and SAVES adjustments made in to the DCU or digital convergence unit in the set.
I STRONGLY SUGGEST YOU TRY THE OPTION MENU FIRST, IF NEED DETAILED INSTRUCTIONS I CAN LOCATE THEM FOR STEP BY STEP OF THAT.
SEE IF IT CLEARS THE MAIN ISSUES UP FIRST---IF YOU TRIED TO ADJUST CONVERGENCE IT MAY NOW BE MESSED UP BUT UNLESS YOU GET THE SET BACK TO WORKING SOMEWHAT NORMAL NOTHING TO WORRY ABOUT.
keep in mind I do this here for free and have worked on hundreds of these Mitsubishi sets.
