SOURCE: mitsubishi model ws-55859 tv is red and red

If it is WS-55859 and you go into the customer menu and find red or blue are skewed and will not adjust---you have a convergence problem.


This model uses a single STK-393-110 convergence chip--it and any of the protect resistors around it that are bad will need to be replaced and the set adjusted.

The chip can be purchased on Ebay for about 12 dollars plus shipping--total parts cost should be under 30 dollars!

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS MODEL.

They tell you everything you will need and how to do the repair---If you or someone you know can do it I can post or get the instructions to you.

If you cannot do it shop around your area--most shops are going to get 300 or MORE for this kind of repair and many will not do in in your home--Any good tech can do it in your home in about 1 hour--I know as I have done hundreds of them.

If you have questions or need help let me know--I am here to help people.
