Red convergence on my ws-55809 is off


The lense adjustment won't help. There are two convergience chips inside, each has 16 pins. If you take the big tray, with all the boards, out and turn it over, you will see that one of the chips has a pin that goes to a contact labeled, "RH." You can't miss the chips, they are stuck to a huge, finned heat sink, about 4'' x 7". Check the continuity from that pin to it's contact with an ohm meter. You may get lucky and get by with simply a re-solder or jump on that pin. Those convergience chips are like computer processors, are subject to extreme heat, depend very heavily on their heat sinks and cooling fins and could easily get hot enough to break a solder connection. Like computer processors, they should have been designed with fans as well as heat sinks. Don't kill yourself. Even unplugged, a tv has enough stored energy to be fatal.

Where are the covergence controls in ws55809 tv located


All convergence adjustments on this set are done with the original remote control--you will find the CONVERGENCE in the customer menu---if set will not adjust there you have a circuit problem.

I have fixed hundreds of these sets--if it will not adjust let me know and I can tell you what is needed to fix it.

Ws55809 tv picture bows at top and bottom. Also has shadows. Is it the bulb and where do I get one.


You have a convergence problem. The 3 picture tubes are fine. The small signal module needs reworked. The board with all the rca jacks.

I need to replace the convergence chips in my Mitsubishi WS-55809. Could someone send me the instructions to do so, as well as any other need info for this task? Thanks, Jason utilitypigeons@aol.com


There should be a diagram somewehre in the tv set itself. If not, do a diagram search on your model number on your television, and it should show where those chips are.
