Wow, I was expecting more heavy lifting stories than I'm seeing. For those complaining about 200lb televisions those are not bad at all. So, I'll bite and tell my tale.
About 5 years ago, my wife and I bought our first house. Only having apartment size furniture and no appliances to move, we did it ourselves with the help of family and friends. The one items we were most worried about was our 300+ pound 40XBR700. It had taken me, plus 3 large delivery guys to get it into our second floor apartment, and now we were wondering how to get it back down. Furthermore, it was going in the upstairs game room of our newly finished house.
It took 5 strong 20 somethings (me being one of them), to get the TV down the narrow outdoor apartment stairs. The TV got a couple of small scratches on the front edge from being bumped against the stucco on the tight turn, but it made it down okay. We lowered it into its original box and carted it to the moving trailer.
Once at the new house, we carted it to the front door and unpacked. The same 5 of us then lifted it out of the box and carried it to the bottom of the stair in preparation for the part we were all dreading. From their, we lifted it and started up the stairs (thankfully a straight shot this time) with three on the bottom side and two on the top. The goal was to simply set the TV down at the top of the stairs. We made it up after about 5 minutes of grunt and sweating and were in the process of lowering to rest on the upstairs carpet. One of my friends managed to catch his elbow on the stair rail during the lowering, and proceeded to rip the entire railing out of the wall (16 feet long) leaving large holes in the sheet rock of my brand new house.
After a few minutes of laughter and full removal of the railing hardware, we brought up the matching stand for the TV, lifted it to its stand, then slid the TV and stand along the carpeting (taking 3 of us to slide it). We slid it the length of the upstairs hallway into it's new home in the game room.
For the last 6 years, it has only left that spot twice. On to occasions, the builder had to come in and repair the floor in that room to remedy some noisey floor boards. Each time, the set had to be slid out of the room and down the hall. Which took my wife and I considerable effort.
All turned out well with the stair well too. The builder installed rail was painted white and never going to stay clean. I replaced it with a beautiful stained oak rail and easily patched and painted over the sheet rock damage. The new rail is also significantly stronger than the old one.
