It was working fine, until I moved it into my new house, I just powered it up for the first time in about a month today and now it makes this weird screech squeally sound when I have it turned on, does anyone have an idea on what's wrong?

Maybe a broken solder joint or a crack in the PCB near the flyback or other heavy components?

nevermind, the noise stopped on its own today.

sometimes the core of the flyback will become loose and make noise. A thwack on the side of the set usually stops it.
