This past weekend I did complete my TV mod in the living room. Again, since we are seasonal campers and our trailer will not move, I had no desire to have the TV retract out of the way. If you do trailer this maybe this mod isn't for you?
I removed the TV from the lift and mounted a 2 X 2 piece of plywood to the lift assembly. Then I mounted an articulating TV mount to the plywood. From there all I needed to do was mount the bracket to the TV and attach assembly to arm. I guesstimated height since I would be able to fine tune height with the lift motor. With the articulating arm mounted to the plywood, the TV will not retract into the opening in counter top. I didn't look to see if I could find a more slimline articulating arm to use.
If you want to do this mod and do trailer, you probably do not want to leave on arm while towing. It only takes the removal of 2 screws on the mounting plate to the TV to get TV off the arm. Then the TV would need to be stored securely obviously..
I used this arm...
I was able to adjust the height so that the TV sits directly above the soundbar, and the sub I put behind the recliners. Now the TV is viewable from all angles in the living room/kitchen. My DW actually thought I went out and got a bigger TV lol.. This setup is ideal for my situation. I lowered the TV down about 6" to gain access to the back and left at that height for the rest of the install.
Sorry the picture is so dark.. I can try to get better ones and pics of the backside of TV if anyone interested. I also needed to convert the coaxial out to optical out by buying a converter off Amazon. My LG soundbar only had 3.5mm input jack and 2 optical inputs..
