Question about Toshiba 50H81 50" Rear Projection Television
I have a toshiba model 50H81 CRT type rear projection TV. Just bought it second hand and it appears that the red tube is rotated slightly from the other two which causes the red convergence to be bad at the lower left of the screen. Adjusting the convergence on the menus works for overall convergence, but because of the rotation the red will always be misaligned at one corner or the other.
I have removed the panels to be able to see the yokes of the tubes. The question is: what is the best way to rotate the red tube to get them all into alignment?
Are you sure it's yoke? these are know for bad convergence amp ic's
other wise it's a screw and glue holding the yoke in place loose the screw and try to break the glue with out breaking the plastic on the yoke, the other thing you can do is adjust the magnets which have tabs on the yoke. i would mark the position's of everything on the tube with a sharpie so you can get it back to start.
Convergence amp ic bad
