I believe you have the same type of swivel entertainment system I have in my Jayflight 29QB. Here is what I did to hang a 32" VIZIO LED TV hung in the entertainment swivel cabinet. You may be able to go slightly bigger, but I did not want to risk.
To mount the VIZIO TV we purchased a VideoSecu wall mount from Amazon
http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1 that attaches to the wood in the TV area. I had to modify the bracket slightly to accept the screw pattern in my TV, but that was no big deal. Also used a 1" bolt to attach the other side of the bracket to the wood instead of the 2" bolts supplied. I figured out that the swivel cabinet has about a 1.25" thick piece of wood with a small gap as well before you hit the mirror on the other side. I like this mount because it has 2 quick releases so I can take the TV down during travel also it has just a slight angle of downward tilt so when we are in the bedroom it is the right angle. I would leave the TV mounted, but it can slide from side to side on the bracket if not careful and I do not want to take any chances.
