Class action normally means you get even a smaller nothing than you would get in a direct action, but, if you win, your lawyers, despite the reduced per-plaintiff recovery, get many times more than they would in a direct action. (It also means that, for N plaintiffs, the defendant, if they lose pays an amount x where 1 << x << N times the amount they would pay with one plaintiff.)
Actually, what you probably want is a mass direct action, not endless individual lawsuits, but, first, you want a legal rule of recovery far better than you would get even for actually taking back the TV under current law.
You're going to be out thousands of dollars and get nothing.
