OK, so I hooked the tuner up properly and I'm still not getting anything out of the tuner yet, no lights or anything, so I wonder if the tuner is just dead on this TV? Although when I tune through the channels with the power tuner, I get a little disturbance on the screen like the tuner is trying to pick something up, but the screen just goes blank.
