Question about Televison & Video
I have a rca that has no picture and makes a high pitched sound what do u think is wrong the picture tube was replaced about six months ago
The high-pitched squeal is from the power supply, usually because of failure of the horizontal output transistor, flyback transformer, or both. Without a specific model I can't give more definite information about part numbers or likely costs. But repairs of this type usually have parts costs in the 10 to 75 dollar range (depending on just which parts are bad, and where replacements come from) plus whatever labor costs the repairer charges.
