I had a '12 SV 264 which is the same floor plan. There's a tapered fixture that the TV is screwed to. In the middle at the top is a clip to keep it from bouncing up and off. I can't remember if you have to push the clip toward or away from the TV... but with the TV pulled all the way down, you can release the clip and lift it off... To put it back on just position it correctly and let it drop onto the taper and the clip will engage. My TT came with an outside TV mount that was the same as the taper inside. I could move it between locations, but I never did. I just bought another small TV and another tapered mount.
