Cabinet movement

[trlrboy]

I have a 3400RL and I'm noticing movement on the cabinet that comes down along the wall from the ceiling cabinets to the countertop. I can see that the bottom of the cabinet has moved about 1/2" toward the TV but I cannot see where this piece of cabinetry is fastened to the wall or the counter base.

I believe it is suspended from the ceiling only. Some caulk would help to keep the bottom from moving.
