i got it out of the box plugged it up and everything seemed to be working great. Then after a half an hour i turned everything off and left the blue screen on and went and ate nachos for 20 mins and then came back started it up again and there are a bunch of purple and green vertical lines!! Does this mean the lamp is dead or is the whole thing shot! Im so mad. I keep trying every half an hour to see if the picture is back to normal but no luck. any advice im really freaking. The brand i have is a panasonic l592u. thanks.
