Question about Mitsubishi WS-55819 55" Rear Projection Television

1 Answer

Convergence Problems My WS-55819 intermittently has horizontal convergence issues. After the television is on for a while, the convergence remains OK in the center of the picture but towards the left and right sides of the screen, the reds, greens, and blues don't line up. In fact, the reds are too high on the left and too low on the right. It will intermittently "snap" back into place and then just as quickly snap out of convergence. Also, as it snaps in and out of convergence, there are numerous horizontal black "noise" lines going across the screen.Any ideas of what to check or replace?

How do I fix the 2,2 error on the ws-55819?


install the convergence repair kit for your model. The 22 error is almost always caused by shorted Convergence ICs and blown picos. You can get the convergence repair kit for your model at www.tvrepairworld.com

I have a ws-55819. the picture is out of focus, more so on the left and right, less out of focus in the middle. Its like there are 3 separate pictures, out of alignment


Thats caused by a failed convergence IC. You can get the convergence repair kit for your model from www.tvrepairworld.com The kit contains the parts and the CD with instructions for the repair.

Can not align red even though convergence board WS-55819


Did you replace the center board with the STK-392-570 chips or the Digital convergence board mounted on it?


98% of the time if you have a convergence problem it is on the center board---the small board on the left under the metal shield box stores and controls the convergence of this set.


WHICH DID YOU REPLACE?

I am here to help----I have fixed hundreds of Mitsubishi sets with convergence troubles.

Mitsubishi WS-55819 TV Wont turn on.


code stands for loss of vertical. I had one of these if you can check pico fuses, check the ones on the main power board the one with the 2 convergence amps if any of them are blown then most likely the convergence amps have shorted out.

Picture problems and tech question


You already know more that 90% of the "techs" by being informed.
just allow the tv to set unplugged for 24 hrs and all should bleed fine.
to be certain just bleed the big caps , the tubes will not bleed back into the circuit.
just use plenty of flux and wick to remove the solder as fast as you can.
and the issue with ic is that they are all from the same die just that the center ones are mil grade which you will not likely find a source for and the outer are commercial grade which is all you can buy.
being your purchasing a part out of production good luck even finding it. if you have and intermittent issue it is likely a heat and capacitance leakage issue , finding it will be hard,
an air gun and remote temp might just do the issue fastest.
try running with the back off and a fan aimed at the circuits, if it runs longer or forever then it should be easier to locate.
