Re: heavy object to move
Get 3 people, 2 on the ends of the tv (there might be handles built in there) and put the third person on screen side of the tv. Trust me, that will help a lot, the screens on those tv's are so thick and heavy. I don't know about going down the stairs though, how wide it is if you can fit 3 people like that.
And just take your time and go slow.
When all else fails...Ham Radio!
I still have the same old HP DV9700T laptop I've had for years...still kickin'
