When I resetup my Plasma after 1.5 years of storage, it did not work. After 10 seconds, the power shuts-off and the red power pight blinks 11 times. As indicated by the Concierge service, it is a mechanism that shuts the entire system is there is a low voltage, over-temperature and other precautions that would make the TV damage itself.
I opened the back panel and powered the TV and viola, one of the fans are not turning! Probably because during transport, the connectors got loose.
Anyway, for 11-blinking red lights, its good to open the back (being very careful not to touch anything) and check if there are burn marks, bulging capacitors, cracked diodes, melted wires and other signs that are not common -- like none rotating fans.
