SOURCE: I have a 64 inch

Ha Ha, I had the exact problem. I think mine is the same model of TV as well, I have a 64" Pioneer made in 2003. So my TV would hit the slanted ceiling above my stairs as I tried to move it down. I first took off the wheels of the TV and this helped but it was not quite enough. So since the bottom of the TV is flat with exception of the side boards and the front trim. I removed the front trim temporarily and cut off the side boards with a circular saw till even with the flat bottom. This gave me 2.5" more clearance which was enough to fit the TV downstairs. Hint if you scribe the cut line with a utility knife it will reduce chipping.
