Audio but only black screen for video on WS65807


First, the set has a hard reset but it will NOT affect convergence which is stored in a separate area of the set.

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.

Red distorted color near top of screen not having much luck with trying to converge the lines on the tv set form. already tried factory reset


Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

LINES ACROSS TV


Good Day, YOU ALL;
Try this: 1. E2RESET DOES NOT RESET THE CONVERGENCE. THE CONVERGENCE CAN BE RESET BY PRESSING "MENU 12598970", IF THIS DOES NOT RESET THE CONVERGENCE TRY "MENU 125968970"

2. CHECK C2P08 100 UFD 16 V OFF PIN 3 OF IC2P03 (3.2 VOLT REGULATOR) ON THE SIGNAL PCB.

Also you may poor solder connections on the vertical output IC or on the CONVERGENCE IC's.

Hope this helped, good luck, big IRISH.

Warped picture


Good Day, jamelpp;

Sounds like the warped picture may be caused by the convergence output IC's, but try this first:

To reset Convergence


I did not read the question all the way. I still need to know the make of the TV set. If the picture is all blue, that's not an indication that the convergence needs to be reset. That sounds more like a problem with the video driver unless you have no sound. I really need a little more info on the set to say for sure.
