No Picture! The Backlight Works Though.
LG 47LG70 - LG - 47" LCD TV,It powers on just fine and the blacklight works but there's no picture, it's just a dim dark screen with the blacklight highlighting the screen. I've checked the capacitors and they're still good. So what else could it be? How do I fix it?

If you do get sound, see https://www.youtube.com/watch?v=ysHfaQKI45M. If you get neither picture nor sound, try the three numbered steps at http://bit.ly/2AeqOGu. If the problem persists (or if you require further explanation), you'll have to obtain a walk-through from LG: use the contact information here--https://www.contacthelp.com/lg/customer-service. Good luck!
