"Emerson" TV problem

[crt89]

I have a 20" "Emerson" branded CRT TV made by Funai that has a fuzzy picture. After a while of leaving it on, it starts making a loud high piched sound. My father is planning to throw it away, but not sure if it's a simple fix. I'm assuming it's not worth fixing because of the era of it, so I will probably get rid of it unless its super simple. It's from October 2008.
