The green color is off. I am thinking that it is the auto convergence. I want to try to fix it my self (I love to do these kind of things) but I do not want to buy the wrong part.


This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300
To Find the IC's look for 1 or 2 large (4in x4inx1in) aluminium heat sinks. the part # is labelled on the face of the IC itself

Convergence IC replacement


No as long as the STK number is the same they will work. Just be careful where you get the parts as alot of places online sell cheap chinnesse made ICs and they wont last. I usually get mine at the following link, and I havent had any trouble with their ICs.
