You will have to inspect the convergence circuit. See if there are burns on the capacitor or there could be a problem with the circuit itself.

We went to auto focus on our tv. It shook wildly the when the picture came back the picture is bent. When looking inside the tv the green and red are being projected bent at the top and bottom. Please...


You need to replace the convergence IC stk392 -110...2 resistors and a fuse. located in the deflection board of your tv and after you can press auto focus and the picture will be normal.

Picture out of focus. lines in tv kinda jumping


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like 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-$400 Be sure to vote/rate me if this helped Thanks!

Jvc av65wp55 out of focus


When you say you changed the focus block, did you adjust each color individually ? Most projection sets are adjusted by covering 2 lens and focusing each one seperately. Try this , it has always worked for me

If the red is colored outlines or 3d picture then it is a convergence problem.

If convergence is ok, then most likely screen/focus control assembly.
