Question about Mitsubishi WS-55819 55" Rear Projection Television
The TV has had about 1000hours on it in our house and was used before that. We have had to replace the convergence chips before we could use it.
Before you call for help is a good idea if you check the solder conections to the convergence Ic's and resoldered them and while you are there check and resoldered any overheated areas.If the soldereing corrects the problem you will not have to worry about convergence adjustments,as long as the set is unplug you can carefully work in the chassis without having to touch the anodes of the picture tubes,stay away from them.Lets us know how it goes.

SOURCE: Convergence not lining up
Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.

Parts for $80 to 90?!?!? HOGGWASH!! It's $21 at mcmelectronics.com for an orignial Sanyo. For a WS-65711 it is indeed a STK393-110 and you only need one of them. I've heard that this usually the culprit when there are convergence problems. The pico fuses can go, but that's pretty rare. If you can solder and feel comfortable inside your TV, then this can be done at home so you'll even save on the labor. I suggest buying the part yourself and asking them to install it.
