Mitsubishi WS 55819 with a convergence

I have a Mitsubishi WS 55819 with a convergence problem. I have replaced both of the STK392-570 ICs.
Now the blue Convergence will adjust but the red is still bowed at both ends and will not adjust. Is one of the STK chips for the red and one for the blue. If so which one is the Red. If not what other problems do I have.

    Where do I find the convergence ic's in my Mitsubishi ws 55819 tv?  Opened tv and did not know where to look.  Help please

    when first turn on tv, have "happy face" curve at top and "sad face" curve at bottom of screen, with double image in red and green. After a minute or so disappears. After two weeks of this, now getting full screen green background then changes to red background, also lots of "bleeding".

    Thanks for the help. The IC's did the trick. I replaced both IC's but one of the replacements was bad. I ordered a new one. and replaced one at a time. I got lucky on the first try.



    Thanks

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 Mitsubishi WS-55819 and the screen is curved and looks 3d. The colors are also blurry. When it warms up it looks better. Any suggestions?


It could just be the solder on the convergence ICs which needs to be reflowed. If that doesnt help then the ICs will need replacement. Your model uses 2 of the STK392-570 ICs. If you need further assistance please let me know.
Thanks

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.

Convergence ICs are bad need to be replaced. You will need to replace both of them also check the resistors right next to the IC often 1 or 2 of them burn out when the IC goes.

Convergence problems WS-55807


On this model if the fuses that protect the convergence circuit would open up, then the set would not come on. The convergence ICs probably have a cracked solder joint on the foil side of the circuit board.Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. Hope this helps.
