Replacing the AV1-LED Stick PCBAs

Although the AV1-LED stick PCBAs are designed to give years of
service, replacement parts are available. LED colors and replacement
part numbers are shown in Table 2 on page 18. Because the stick
PCBAs are connected in series, you must replace all three.
The stick PCBAs are held by a retaining bracket at 60 degrees to each
other. When joined with the bracket, the PCBAs connect to pins at J5,
J7, and J8 on the power PCBA. The stick PCBAs are secured to the
power PCBA with a Phillips-head screw (Figure 1 on page 8).
SHOCK HAZARD—Do not connect the light to the system while
the power is on. Failure to heed this warning may cause serious
injury or death.
To remove the AV1-LED stick PCBAs:
1. Turn off power to the system.
2. Loosen the lens locking screw and twist the lens counter-clockwise
one-quarter turn. Remove the lens from the upper housing.
3. Remove the Phillips-head screw retaining the bracket holding the
AV1-LED stick PCBAs.
