If you go into the customer menu with the Mitsubishi remote and the colors are skewed or will not adjust:
If red or blue will not adjust in some direction--you have a Convergence circuit problem---
This model (WS-55809) uses two of the STK-392-570 Convergence IC's---
Green
for a good reason is not adjustable in the customer mode---it is only
adjusted for the Geometry or straightness of the picture and then red
and blue are adjusted to it.
If you are able to do this repair
yourself you can save the set and a lot of money---most shops charge
300-400 for this type of repair in this set.
You can buy both
chips for about 14 dollars on Ebay- and I have step by step---start to
finish instructions for this repair in this set--they tell also
everything you will need to do and what you need.
If you want the instructions let me know---I am not allowed to post MY
email here...but I can post the instructions here.
Not everyone can do this repair---Let me know if you have any questions or need advice----
If
you get someone else to do the repair make sure BOTH chips get replaced
or the set will have the same problem again in a few months.
This problem should be fixable right in your home--I have done hundreds of them and have two sets to do this type of repair on tomorrow.
