CONFUSED SHARPLY :
My LC60LE64OU SHARP AQUOS TV WAS TURNED ON BRIEFLY THEN IT TURNED OFF INDEFINITELY WITH THE POWER BUTTON FLASHING. TRIED UNPLUGGING WHILE HOLDING THE VOL UP/DWN BUTTONS THEN RE PLUGGED THEN RELEASED THE BUTTONS. NOTHING HAPPENED EXCEPT THE SAME FLASHING.
So, i got the 70" version, every time the power goes out the ***@ing light on the bottom blinks and it won't turn on. unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in. Thats whats worked for me - hope it helps someone out. Gonna get a sony next time, that one has lasted over 7 years…..
