Refer to procedure in Service Manual.
After left and right side panels have been removed, opening the monitor
consists of separating the front bezel and rear housing subassemblies. The
subassemblies are secured to each other by two locking tabs on the rear
housing at the bottom of the front bezel and two locking plates that secure
the top of the bezel to the rear housing (see Figure 3-7).
