Golden, What were you using for the Mount? You said playbar so not sure if your was on an articulating or not. Not sure if you use Snaps low profile/tilt mounts on the Sony's but I fond myself many times having to use two different sizes. like medium for the shorter arms due to the low placement of the holes (at least least years models) and large or XL for the plate especially if the studs are off center so the TV can be shifted.
