2000 35 inch TV makes a high pitched noise when TV is turned on.
Is this an RCA or GE? If so then the horizontal output is shorted. And maybe a capacitor or 2. Need model number to be more sure.
My set was making a high-pitched squeal from the Co-ax cable that digital cable comes through. The sound stopped when I would push the threaded connector down or up. I was looking for a way to have constant pressure applied and lifted the tv, as soon as i had it tilted forward a bit the sound disappeared. So I stuck a ball point pen under the back of the TV to keep it in that position and sure enough; NO MORE SQUEAK!
