3. Remove the Main board assembly from the control panel and place on a flat

surface. Remove the top and bottom screws from the Main board assembly

using either a flat-tip screwdriver or 1/4" nut driver. Set screws aside.

4. The following steps involve separating the Main board housing. The

housing for the Main board is actually two (2) panels that fit together.

A. Place the Main board assembly on one end. Holding the housing

assembly as shown, gently apply pressure outward on the green circuit

board connectors until the panels start to separate.

B. Repeat the procedure on the other end of the assembly. Once panels

have started to separate, work the sides alternately until the 2 panels are

completely separate. Caution: Avoid handling the small contrast adjust

component at top of circuit board.

C. Place the front panel aside. Place the other panel (one with main circuit

board PCB attached) on a flat surface.
