All is fixed. I changed the batteries first -that wasn't it. The password said 'locked' so I set a new one -that wasn't it. Turns out their speakers were set to the off position. Also when they tried to played around with the buttons to fix it, they kept hitting the 'sleep timer' button so of course the tv would also shut off -"it just went off -just like that".
