 What does it mean when the TV's red indicator light continuously blinks?

Panasonic utilizes the blinking light as a form of self-diagnostics, similar to the "check engine" light in your car. If you've ever experienced that, you know that a check engine light could indicate anything from a loose gas cap to something that may require more attention. Panasonic uses the number of times the light blinks, to aid the technician in trouble-shooting the problem. The blinking light helps the technician to isolate and diagnose the issue. This in turn speeds up the repair process if repair is needed, helps keep parts costs down, and helps both you and the servicer by allowing the technician to complete a repair in one trip in many cases.
