WS-55511 USES a single STK-393-110 convergence IC.
If
convergence if off and either blue or red will not adjust in some
direction--The chip and any of the 3.9 ohm resistors around it that
protect it--will need to be replaced if they are bad.
Most of the time--just the chip needs to be replaced and the set adjusted.
I have step by step, start to finish instructions for this repair in this type of set.
If
you can do the repair, total parts cost will be under 25 dollars--you
can buy the chip on Ebay and the resistors are easy to check.
I have
photos of the resistors and the instructions tell you everything you will need to do the repair.
If
you cannot do the repair--most shops are going to get 300 or more for
it---if you go that way make sure you get someone to do it--it should
be able to be done right in your home--takes about 1 hour--I know as I
have done HUNDREDS of these sets with this problem.
If this information helped you rate this solution as I do this here for free.
If you need the instructions let me know and we will find a way to get them to you....
