up grading TV's

I just installed a ultra thin 32" vizio (14#) in my front overhead cabinet. I mounted a 13" ht X 24"w pc of 3/4 plywood about 3" back into the cabinet which gives me a nice face plate to mount the articulating (80# capacity) arm on. I attached the plate to the sides of the cabn't w/1-1/2" alum angle mounted vertically and angled to match the front angle of the cabn't. The bottom of the TV extends back into the opening and rests on the bottom of the cabinet. I keep it from coming out w/ a 3/4" strap and buckle that wraps around the entire cabinet and TV. I am still looking for a better way hold the TV in while traveling.I have a space at the top that I will close w/ some type of black fabric. There is still room inside the cabinet for a sound bar in the future. I was able to connect the new TV to my radio speaker sound system that the old CRT TV could not do. It sounds better and looks great.
