Question about Proscan PS36800HR 36" TV
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
