THANKS!! Your suggestions and comments did the trick. Especially the pictures found in the link provided by "007". (Here are some pictures
from one of them " TV TO LCD CONVERSIONS" section.) One of my side screws was discovered by feel only as it was around the corner in the driver's side cabinet. Side screws did not have to be totally removed. Only backed out enough to clear the inside tabs.
Again, thanks to a great group and a fabulous blog site. Lots of knowledge out there.
