Question about Proscan Televison & Video
Tv is about 2 years old, no problems until here recently. We took the back off and blew the dust out of it, no help.

A high pitch noise comes normally from blown capacitors from the motherboard or the power supply. But mostly high pitch noise comes from power supplies.
You could have to open up the power supply to see them.
Verify if it is the case and replace the faulty part.

I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.
