Remember I can't tell you because LG made some thousand models across the world, so my advice is pack it up and return it if the seller and maker can't tell you this answer.
It's a bad indication of future support. Did you ask both seller and maker yet?
PS. LG reps rarely show up here. And volunteers can't answer without the full model number.
LG instructions say on/off button on the set is right under the logo. It is not.
TV will not come on and they say to hit the on/off button on the set. where is it
