IF you go into the customer menu and select convergence look to see if blue or red is skewed or will not adjust in some direction---you have a convergence circuit problem.
kp41T65 uses two of the STK-392-150 CONVERGENCE IC CHIPS.
Most likely only the chips will have to be replaced and the set adjusted with the Sony remote, considering you can buy a pair of the chips on Ebay for about 12 dollars plus shipping if you or someone you know can do the repair--you can save the set and a lot of money--most shops are going to get 300 or more for this type of repair.
If you are able to do the repair I can assist you with general instructions and what you will need to do it.
This kind of repair in the home usually takes about 1 hour--once it is fixed it will not have the same problem again for 5-8 years---lifespan of the chips.
