Projector is in Standby mode but cannot turn the
lasers on
The lasers do no turn on while the projector is in Standby mode.
Details
Possible causes include:
1. 48 VDC power supply down
The 48 VDC low voltage power supply (LVPS) requires control signal from the housekeeping
board. If the communication harness from the housekeeping board to the 48 VDC LVPS is
removed or not seated correctly, the LVPS does not output power.
2. Bad laser communication for the low voltage current source (LVCS), high voltage current
source (HVCS), or laser backplane (LBP7) boards due to damaged or improperly connected
harnesses.
To understand the power workflow, refer to the diagram in Projector does not turn on (on page 5).
Resolution
1. Check the 48 VDC power supply LED.
Use the LVPS status table to help determine a resolution.
LED status Output status Action
Solid green DC Output OK Indicates power to the power supplies. Proceed to
step 3.
Solid orange DC Output OK, in remote
control mode Check the communication (CN2) harness into the
power supply is fully seated and connected.
Slow blinking green Output Not Enabled There is power but the supply is not enabled.
Check the communication (CN2) harness into the
power supply is fully seated and connected.
Fast blinking red Over Voltage Too much power is coming into the power supply.
Ensure a certified electrician checks the line voltage
and supply from the wall.
Solid red Over Loaded A potential short in the output of the power supply
occurred.
Inspect the DC (secondary) harnesses are fully
seated and connected.
Inspect the boards to ensure they are
functioning.
Slow blinking red Over Temperature The power supply has over heated.
Potential air blockage. Inspect the air intake to
the power supply and clear any blockages.
Check if the projector is operating in the
specified projector temperature range.
