Looks like a mainboard fault with both the Backlight (LED ON) & Tcon On voltages missing.

I have this same LED TV being discussed here, although on mine, when powered on, the splash screen shows and after about 3 seconds, the backlight flashes a bit brighter, then the set shuts down. The only thing that I have found that makes the set do anything different is if I power it on with the LED plug disconnected, it stays on. Where should I go from here? Thanks...

You should have started your own new post for your TV. Nevertheless, it would seem you have a backlight issue.

Thanks for the quick response...and I assure you that it would have been in a new post but as it was my first post on this site, was unable to do so... again though, thanks
