I bought a crappy $120 Apex 20 inch TV in december, and of course, the week I decided I was going to keep it and threw away the packaging, it started to make a loud whining sound. I did not purchase a service agreement from best buy since the TV was so inexpensive. The whining starts when the TV is turned on, but after a few minutes, will gradually fade out. I have a Playstation hooked up to it via S-video, but when I push in or pull a little on the coax in (antenna) the noise will change or dissapear.

Does anyone have an idea of what this noise is? I remember a similar noise on a terribly old zenith when I was a kid. I don't know if this is a result of an inferrior unit (Apex) or some kind of fixable problem.

I appreciate any input I can get because as of now, my wife won't turn it on, so it doesn't get a lot of use.
