Bottom of tv appearing at the top

[Ian12h12]

My UE40D6100 seems to be on its way out.

I know its old, but it was doing just fine, and now the bottom of the screen appears at the top, and if I grip tightly on a very specific part of the screen... it stops (see video). Any idea what it could be? Is it repairable? If it is, can I do it? Is it worth the cost?

Could be as simple as a loose or worn cable that your squeezing is making the contact.
