Re: Toshiba 50H13 TV with No Picture
the convergence circuit has failed.
the same voltage supply path that drives the "jungle" is shared with the convergence and has "opened" as a result of the shorted convergence amplifiers.
the "jungle" is what processes the picture for display.
if the picture has good colors, brightnes and contrast when it was working, then it is worth repair.
the convergence circuit is what converges and corrects the geometric distortion on the screen from the result of projecting each color tube (red, green & blue) to a mirror and then to the screen.
