Thanks a lot, you saved me from baking the motherboard :) It really DOES work. I think it must be the equivalent to the Reset to Factory settings or Initial TV setiings or something for those who have access to their Menus. Thumbs up!
I have a the LG tv model # 55uf6450 it was stuck on the start up screen I did what u sayed but didn't work then I read that I can bake the mother broad in the over but when I was about to do it I notice a button on the mother board so I hooked it back up turn it on then push the button it restarted and know working fine looks like it was a reset button on motherboard
You have to change tv because mine did this the next day i bought it and my neighbour who is an ingeneer couldn't fix it and said i had to give it back so good luck
