Good Day;

Sounds like the Convergence IC has failed. Replace > STK393-110 > part # 267P155010 > TV uses one IC. Good Luck, big IRISH.

Blurry picture


By focus is the set looking 3d etc--called a convergence issue---if so go into the menu with the Mitsubishi remote and see if it will adjust---if off and will not adjust in some area of the screen the set needs the convergence chips replaced.

If convergence is good and not the issue describe the problem a bit more----these sets have 3 picture tubes with lens---from rear of set (safest way) the lens can be cleaned with a lens cloth---dust on them will make the picture look darker and dull looking and usually is done one time a year--do not try to adjust anything until you try this first.

Mitsubishi ws-55515 intermitent blurry picture


A bad connection somewhere--when it happens if picture is 3d look in menu for convergence and call up the grid of lines--if they are not perfect you have convergence issue which usually requires parts to be replaced.

In this set sometimes the chips will become flaky and convergence will jump in and out.

Mitsubishi WS-65611 Repair kit from TV-Repairkits.com no fix.....


I have a few ideas but they all will require some more information from you. I know these sets very well-if you fixed the convergence problem my hat is off to you--it can be a do it yourself job but not the most easy set to do it on.

Let me assume you adjusted the convergence in the customer mode--it does on any of the HD models have to be adjusted in the regular and then the HD modes.

The only other thing here that may be the problem is FOCUS. A simple way to determine this is to remove the back cover--turn the set on and call up the advanced convergence grid---then cover the lens for each tube one at a time--with red and blue lens covered are the lines in sharp focus or look blurry?

Repeat this with only red or blue not covered and see what you think--if one of the tubes is out of focus you will see it there--

There is also a TECH menu for adjusting the convergence-like the customer menu but it saves the adjustments into the set's memory--you will need to hit menu and a four digit code based on the actual model number of the set.

Check to see if focus is or is not your problem-easy to tell--green, red, blue lines will either be sharp or out of focus--if out ask and I will tell you the simple way to adjust that.

If this information has helped you rate this solution as I do this here for free.

if the red line is blurry and you have adjusted the screen focus control and does not work then you prob have a bad red CRT or bad red CRT fluid.........

convergence STK have nothing to do with the red being blurry
