Nice to meet all@ I'm David and trying to help my dad out. He purchased a samsung QN75Q7FAMFXZA about a year ago. The TV set in a box for five months while we were building house and went to reconnect to one connect box. I get TV to come on but saying connection from box to tv doesn't exist.

Local TV repair companies when I mention one connect say" what" and have no clue.
