Touch Panel Controller Or Projector Head Problems On Startup; The Projector Leds Or The Mcpu Board Power Led Are Not On; The Mcpu Board Power Led Is Not On; Mcpu Board Power Led Behavior - Christie D4K2560 User Manual

Touch panel controller or projector head
problems on startup
Check the following to determine if the touch panel controller (TPC) or the projector head are
experiencing problems on startup.
The projector has two sets of LEDs to help distinguish how far into the start-up process it is when a
problem occurs.
For more details, see

The Projector LEDs or the MCPU board power LED are not on

Solution 1
If AC power has been applied to the projector head, verify the power source.
Solution 2
If the AC power source is good and the AC power is applied to the projector head, check the LVPS
and all the harnessing going to it inside the projector.

The MCPU board power LED is not on

If the AC power is applied to the projector head and the projector's LEDs turn on, the MCPU board
or the ABP must be replaced. Replace the MCPU board first and if the problem is not resolved,
replace the ABP.
• If replacing the MCPU board, indicate that the Power LED is non-functional.
• If replacing the ABP, indicate that power did not reach the MCPU board.

MCPU board power LED behavior

• Solid yellow—The MCPU board must be replaced. Indicate that the MCPU board failed to
initialize.
• Blinking red—The MCPU board must be replaced. Indicate that the MCPU board failed to
initiate the control FPGA.
• Blinking yellow/green—The MCPU board is running in recovery mode and needs a software
upgrade followed by a AC cycle of the projector head.

Touch panel controller does not connect

If the projector LEDs display solid yellow and the touch panel controller (TPC) has power but does
not connect, the projector head is fine. However, a problem could exist between the TPC and the
MCPU board.
• Disconnect the corded harness to the TPC and reconnect it. You may need to replace the corded
harness.
