Just mounted a RCA LED24C45RQD 24-Inch 60Hz 1080p HD LED TV with Built-In DVD Player in the bedroom of the Coachman. Looks real nice and should work well in addition to the TV in the living area. (need to peel the stickers)
Nice TV but very odd VESA pattern of 100 (4") x 75 (3"). I bought a mount that has a 100 x 100 and a 75 x 75 VESA so I figured it would work. The problem is the holes are 4" x 4" or 3" x 3".
I looked for days for a new mount that would fit the RCA but nothing was VESA 100 x 75. I made a couple of adapter plates so now it works great! (you can see how the 4" holes do not line up vertically with the 3" holes)
One more thing... Do not go by the TV backer sticker. The backer plate sounded / felt like it was there but was 2" below my bottom hole and is only about 3" tall. My mount plate is 5" tall. I used 2" wood lags (pre-drilled holes) into the wood stud next to the TV backer sticker.
Just need to find some beige caulk to fill my oops holes.
