Decided to jump in and try to figure this out. I removed the side panel on the left which exposed the tv mount. It is a brace that is attached to the cabinet which utilizes standard Vesa screws. I will have to make some adjustments to the cabinet and brace due to the smaller footprint of the new 32 inch tv. Very doable and glad to be rid of that Jensen tv.
I have a 2010 Chateau Citation 29BG with TV over the front cab. Had to have long arms and steady screw driver to remove the Jensen TV from the mount. Put a new Samsung 32" in but now have a space all around the TV as the Jensen was a larger overall TV. In addition, the TV sits about an inch inside the existing space and not flush with the opening.
Did you have to have some new moldings cut and stained or painted.
