    I have the same problem. I have the same tv and I turn it on and after it comes on it just shuts right back off. The light on bottom shows that the tv is on and then it goes red right before it shuts off. The only solution I have found is that you have to keep it unplugged whenever you're not using it. If you keep it unplugged when not in use and then you plug it in before you use it then it should work. I hope this helps.
