Once the rear housing is removed, choose which part of the monitor to work on:
• Rear housing components. For details, see "Disassemble the rear housing."
• Main chassis. For details, see "Disassemble the main chassis."

Reassembly notes

• Route the power cable and fan harness cables in the channel on the side of the power-supply
cover.
• When closing the case, verify that no wires are crushed or pinched before securing with
screws. After tightening the screws, examine the seam between the rear housing and the
main chassis to verify that there is no bowing. Bowing indicates that something is preventing
the mating surfaces from seating properly.
