Question
I PRESS THE POWER BUTTON  TO TURN ON THE TV AND IT LIGHTS UP AND THE SCREEN IS BLACK THEN IT WILL SAY SOMETHING BEFORE IT CUTS BACK OFF WHAT MIGHT BE THE PROBLEM?

Answer
Without a model number it is impossible to give you specific advice.

However, if this is a RPTV which it seems it may be based on your comment about auto convergence then it is likely the convergence circuitry has failed. If so, the repair is usually in the neighborhood of $200 to $350 depending on the model and its age.

The above web pages may offer some direction on where to start but if you google your model number followed by auto convergence you will get some information relative to your set.

HOpe this helps you toward an appropriate solution.
