Too much red majic focus not working on red color

    I have already tried both magic focus and manual. I can get all the blue lines in sync and some of the red lines. All horizontal lines are white..it is only the vertical red lines that are frozen out of sync. How difficult is replacing the convergence cables? Can someone with simple soldering experience handle the job. Are there electronic tests that have to be run following the repair?

    When I try to set the convergence for the colour red I get no response.(Cherries are black) I do not see any red base line. In my opinion I have no red. Gary Brown

    Three weeks ago I replaced both convergence amps in my Hitachi 46F500 because the green would not converge. Everything worked fine until yesterday. Now the picture is too red. Even the black screen when there is no video input is red. Any advice on how to fix this??

    My screen always has a red tint to it and I can't get out.

Majic focus lines very broad


Undue the calibration! It sounds like the dynamic contrast is up too high.

Yes it certainly sounds like you have the old convergence outpuyt IC's that have gone bad in this TV set. If you have the soldering skills, and know how to work on printed circuit boards, you can repolace both of the STK convergence IC's. If you do not, you can get the complete convergence board at http://www.ptscorp.com, and the Hitachi board number is JT22056. Good Luck
