Problem Observed: TV flashes green on the screen for half a second upon power-up and instantly turns off into a flashing red-and-green standby pattern.
Probable Cause: Sharp lamp error protection counter exceeded threshold due to an open-circuit LED backlight strip or failing inverter ballast.
Problem Observed: Cabinet power button and remote fail to produce any light on the front panel; TV acts as if completely unplugged.
Probable Cause: Primary bridge rectifier shorted or thermal cutoff fuse opened inside the standby transformer on the Sharp power board.
