Jerry, on the bedroom tv, if the Samsung connections come straight out the back, mine did, I've figured out a way to keep from having to cut the cabinet door. You can get a 90 degree cable and hdmi connector which should keep you from having to cut like I did. Also, the Samsungs use a larger diameter bolt for mounting, don't remember the size. I had to use a grinding stone on my Dremel to enlarge the slots, also had to stack some washers to get the tv level. Hope this helps!
I just looked at your bedroom tv location a little closer, my door was a solid cabinet door, did not have the big square cut-out yours does. You might not have to use the angled connectors. I took my door off and laid it on the back of the Samsung so I would know where to grind.
