Lightning strikes can do very odd damage. Try the usual unplug it all as I noted at http://forums.cnet.com/7723-13973_102-618511/samsung-ue46f7000-hdmi-ports-issue/
I have an LG LED 3D tv and long story short there was a lightning storm at my house last night. My tv will now not come out of standby mode. The red indicator light slowly blinks red if I turn the power on through the remote or manually on the tv. It blinks red 10-15 times and then goes back to standby mode. Also my LG 3D Blu ray player doesn't even power on at all either. My other components including my satellite receiver and surround sound seem to be unaffected. Any thoughts or suggestions? Also everything is plugged into a surge protector and nothing is directly plugged into an outlet.
