Thread revival! I have a LG 47LH30-AU that suddenly no longer accepts HDMI signal. It works fine with component video and my HDMI source works fine with other TV's, just this LG no longer completes the handshake to display HDMI signals. I am not seeing any way to factory reset or check firmware, so is that it for this tv? Do the experts here have any ideas or do I have to throw away a $680 TV after only 1 year of use? I'm not about to watch Blurays over a component video connection so if that is it for this TV I will never buy LG again!
