if you hit info, it keeps popping up a battery(?) meter with an "led" side that's green and the needle is about half way up the two thirds of green, and a "conventional" side that's red and about 1/3rd of the meter. it's weird and very recent. as far as i know is has no batteries involved. yes i've tried the turn it off and on thing, and all connections are unchanged/tight. google don't give me nothing but stores selling the model of TV(it's a samsung) or reviewing it.
