it did stated to restart randomly, sometimes it works for a period of time and the does restart continuously. I did try it on another room.
I did try to google the problem and it may be a problem of the main board which may require replacement, costing like half of the TV’s price.
I have to make a visit at LG custumer support just to make sure, as the warranty did expired.
I’ll get back with more info when i’ll have.
