That would be kind of tricky. Possible if you purchase the right hardware from your local hardware store. I would determine your tv'so weight and then go see what is available from the hardware department. It's going to be a close call, I personally would not try it though. Sorry.

I used 2 drywall anchors that I bought at home Depot that hold 50 lbs each no problems at all.

I have no doubt that this mount would hold my 32" Samsung without going into a stud. 32" units are very light these days.

No TV should be mounted without supports unless you want to come home and find it in pieces on the floor. Save your money and by a stand that will hold your TV.

Ideally you'd like to have the studs to anchor into. However, depending on the type of wall or the quality of drywall you can buy a good enough anchoring system that should be good enough to hold the weight. You might want to play it safe and consult a professional on the structure of the wall or just move the tv to a more secure point on the wall so that you can anchor it into a stud.
