And what if the screen reads WARRANTY SERVICE? Mine has a blank screen as well, except then you plug in a usb data cable, then it wakes up and immediately reads "WARRANTY SERVICE".
After inserting a fresh set of lg hg2's, the screen won't illuminate. Put a set of hg4's from my rx200 in, same story. Connect it via data cable to my of and the screen reads "warranty service".
What might the issue be?
