9 Repair Procedures

1505-1018-000 08/07

9-17

9.4.6 To replace

the Inverters

The Display Unit includes two inverters (one for each backlight).

The inverters “sandwich” the mounting plate and use it as a heatsink. Follow the
procedure in Section 9.4.4 to gain access to the inverters. Replace one inverter at a
time.

1. Disconnect the backlight cable

(A)

from the inverter.

2. Remove the two Nylon screws

(B)

that hold the inverter to the backplate.

3. Slide the inverter out of the sleeve and disconnect it from the CPU harness

(C)

.

4. Reassemble in reverse order.

The “front” inverter

The “rear” inverter
