Question about Proscan PS50700 50" Rear Projection Television
Hmmmmm. at the easiest point i would certainly find a bad capacitor or two. Alwasy suspect a 160 volt to 200 volt cap at 1Mf, 2.2Mf or 4.7Mf. Another suspect would be the 200 volt 100Mf caps that are somtimes used in theses TV. You do have a problem in the the horizontal section. Start with the capacitor check and check for bad grounds. It is the board that contains the high voltage transformer [flyback]. It is this board that will be reworked. Ask a tech, you have some knowledge of the problem and this will keep your cost of repair in your favor. Your proscan TV is a sister model of the well brand known brand, RCA! Hope this helps and thanks for asking!
