Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.


What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Picture is multi color, double shadows, curved


This is failure of convergence out ICs in TV. Qualified TV tech will replace convergence out ICs or board.
