Question about Televison & Video
My first instinct in this is flyback transformer. or if it is three tube projector could be a high voltage splitter lines in picture sound like what is called retrace lines ... this is another indication of a possible bad flyback. high pitch sound is another sypmpton of a high voltage flyback transformer problem. WARNING televisions generate potental lethal charge. the device called flyback is used to generate several THOSAND volts. so be carefull if you take the back of any television. along with the flyback the horizontal output transistor possible could have failed. What type of tv is it? model
