Is it out of focus or does the picture look 3-D? if it does than
The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! Go to http://www.tvrepairkits.com/xcart/home.php?partner=larry
The kit comes with original Sanyo STK IC'S , not those cheap aftermarket or china made IC'S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

On a mitsubihi wt42311 tv where are the STK-392-110 convergence chips located?


Pretty easy to see them as they are marked with that number right on them.

They will be side by side and on a metal heat sink to keep them cool.

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.

I have a Mitsubishi RPTV. Everything looks fine except for the blue colors look blurred. I have tried software convergence but the blue still looks blurred and strange. What can I do?


ADJUST THE ELECTRICAL FOCUS. AND THERE IS A MECHANICAL FOCUS ALSO. SET THE ELECTRICAL FOCUS BY LOOKING DIRECTLY INTO THE TUBE AND ADJUST IT SO THE TUBE SURFACE IMAGE IS SHARPEST. THEN LOOKING AT THE REAR OF THE SCREEN ADJUST THE MECHANICAL FOCUS, ON THE LENS UNTIL IT IS SHARPEST. ALSO IT MIGHT NEED A CLEANING OF LENS&MIRROR. DIRT AFFECTS BLUE LIGHT FIRST.

I have a Mitsubishi Model WT42311 Tv . It will not stay on . When you press the power button it tries to come on but turns itself off. Do you have any suggestions?


Yes, do the self check that this set has.

When you try to turn it on and the power light goes off:

On the front of the set press and hold both MENU and DEVICE (OR INPUT) for 5 seconds and release both buttons.

The power light will blink a two digit error code--for example--2 blinks, a pause and 2 blinks---it will repeat the code at least 5 times.

Let me know what code you find and I will tell you what it means and what may have to be done.

2,2 is the most common and the least expensive to fix.

Mitsubishi Convergence issue


If the screen is out of focus you probably need to adjust the focus on the focus block it is usually located behind the front grill, there are 6 adjustment screws on this block, leave the screen controls along just adjust the red, green, and blue focus screws. When converging a set everything is converged to the green, the blue and red are suppose to come to the green.

Borders bowed inward,blurred red,blue, & green


the next time it is not working go into the customer menu with remote and call up the convergence grid and look---there---if convergence is way off and or comes and goes---this set uses 2 Stk-392-570 ic's and it is quite common to see them become intermittant.

IC's and PICOs replaced but Red Convergence is still off


There is always bias resistors very close by the ic's. You must check all of them. There value will be right on the money, if not you must replace them. You'll see them, they will all be in a row.
Let me know if I can be any further help!

Replacement lamp on mitsubshi tv


That model can have two 3300uf capacitors that go bad on the PWB which will cause the set to detect a lamp abnormality and trigger a red light on the lamp. You can find out more info on it by going to the following link and leaving them a email with your model number and symptom.

Mitsubishi vs 5043


I turned the set on and everything was fine, then the screen went black and mullti-colored horizontal (arched) lines were flashing across the screen. The next day I turned the set on and everything was fine for about 5 minutes then the problem reoccures again. Haven't looked for solutions till now.
