The first job on our "new to us" Minnie Winnie 31C was to replace the TV. Ours has the entertainment console over the cab with the TV mounted in the right side angled toward the sofa.
Removal: I pried off the trim border from the TV opening, then pushed back the two thin, plywood "finishers" that go up each side of the TV. Once pushed back, I was able to pry them out. The finishers and trim are held by thin pins. I also had to pry out the side finish panels from the DVD player space below the TV.
I now had access to the two bolts in the "hold down" strap - removed them and wrestled the old (26") TV out of its hole - man, is that heavy!
We purchased a 26" Vizio LCD to replace the CRT. Obviously it is significantly thinner, and lighter(!) but would fit inside the opening. I purchased two very heavy "L" brackets, a sheet of 3/4 finish plywood and a simple flat screen mounting kit that was basically four buttons and four slide-in holders (Sams Club). I welded two 1/4-20 nuts to the back of the vertical arms of the "L" brackets, then fastened them to the original baseboard using three lag screws each. The plywood was cut to fit the opening, stained to match the trim work and drilled for the 1/4-20 screws. The mounting "slots" were mounted to the plywood and a rectangular hole cut to pass the cabling through.
Prior to mounting the backboard in the opening, I replaced all the side "finishers" such that the opening now resembled a shallow box. Once the "buttons" were screwed to the rear of the TV, it was a simple exercise to pass the cables through to the TV, then "hook" the TV into the "slots". The trim piece around the original opening was replaced and the job was done!
Looks good, works great and I saved about 50lb of high mounted weight! The coach rattles less and is probably good for at least 5mpg better gas mileage! ;D
