You need to try and enter the service mode.
Press CH_DOWN] and [VOL_UP] on the unit and see if it will come on. How many time's is the power light blinking?

Call Sharp and ask them how to clear the memory. I don't remember. The set came on so this indicates the inverters failed to light the panel 5 times and locked you out. The inverters probably need to be replaced but this is a half ass way to be able to watch the set. Post back with the results or if Sharp wont help you.
