Proscan 36in. TV works fine when you first turn it on. THen after about 40min -1hr the picture goes dark. Sound is ok.
You have a problem in the Hi voltage or horizontal drive circuit most likly. Its a slight possiblity that the video is going out because of a cold solder connection from the flyback transformer blanking pulse to the video/sync separator circuit as it does and has happened in the past. This set should only be serviced by a trained service person as there are no real user serviceable parts inside this set. Good Luck

My proscan is model ps35123, the vertical capacitor was replaced, but it shorted out after replacement. Serviceman said it is the transformer on the picture tube. Mt tv is black with a 1/2 inch line in the center of the screen. Does the picture tube need to be replaced or is there some other fix for it??
