Every now and then when I go to turn it on, before the picture comes up (there's always a bit of a delay), I'll hear sound, but then it'll automatically shut itself off and the light on the front will blink and I can't do anything after, none of the controls will work. The only way I can fix it is to unplug it and plug it back in. Which is fine, but very annoying. I don't know why it's even doing it? And like I say, it's only every once and a while, not every time. I tried googling this and I've seen things like adjust settings, or the batteries in the remote are low, but it's neither of those things in my case. If it is a setting, I can't find anything. Is it just a glitch or something with those TV's?
