It has been unplugged for 3 days, and working fine before that. Installed the update sometime in the last week and a half and now the thing will not turn on. It beeps, the blue lights comes on, it clicks, and shuts off totally. Tried unplugging all cords for 4 minutes, didn’t work. Tried the weird one, where you unplug hdmi cord, and plug it back in as soon as you press power and it didn’t work. All this stuff says install the NEW update to fix it. How do I install a new update if the thing will not turn on? What do I do?
