My polaroid flm 3201 tv won't turn on

You can download service manual here:

This is an indication of a protective shutdown. During the startup process, a problem was detected and the unit shutdown to prevent further damage. There's not a lot to go one here. Some measurements need to be taken in side the unit to be sure. A common failure is the capacitors on the power supply board. Any local service shop should be able to get you a reasonably detailed repair estimate. Post the diagnosis here and we should be able to walk you through the actual repair.
