This is the sad story of many a so called smart TVs. I have repaired several of Samsung smart TVs. It is the back light in the panel which fails and company guys advise you for a panel replacement. Once you can see LG symbol means the Tcon is working. It is not the picture which is disappearing, it is the failed backlight which is not there and so you can not see anything. Repairing panel is a tricky job and you need a certain amount of expertise for this. Otherwise you may damage it beyond repairs.
