Can you lay a plasma tv on it's back?

Umm.....You can but you wont be able 2 watch it and it might mess your screen up a little bit! But if you want 2 take a chance at messing your TV up go ahead! Having the tv on its side for a short amount of time will not do any harm to the picture you just have to stand it back up for about 30 min before you watch it. I wouldn't recommend "storing" it on its side for long periods of time though.
