This is REALLY weird. My wife's LED display I bought her a few months ago has no serial number on the pedestal stand. I still have the box etc it came in so I have the serial number from the box, but there's nothing on the foot of the display. There's a black strip where I ASSUME a serial number SHOULD be, but it's black, with nothing on it! I only noticed it since we're packing up all our stuff (moving to Seattle). What the heck do I do if I need a warranty repair? How do I prove my serial number?
