I removed both the TVs form our 98 Mountain Aire last summer. If I remember correctly, I had to remove the front plate of the cabinet completely. I didn't care because we were getting rid of these cabinets altogether.
I think I removed somewhere around 250 screws that day - many of them hidden or almost impossible to reach. Maybe exaggerating a bit, but it felt like that many...
