Like a tard I am I bought a 43inch Sharp smart tv for 120$ without looking at it because it looks perfect it looks new.. Well After I get it home I plug it in and turn it on well after I turn it on all it does is light up that is it! No sound no picture just the screen lighting up from the backlights coming on. If anyone knows a solution or problem please contact me. By the way the model number is LC-43N6100U
