Madrigal Imaging MP-8 - Manual (Page 98)

3) If using an IR keypad, the batteries may need replacement. Remove the
batteries from the battery compartment on the back side of the keypad.
Install new batteries as described in the section 2.3.
4) The keypad may be damaged. If the back panel C LED does not flash
when is pressed, the projector is not responding to the keypad. Try
using a different keypad.
5) If using a remote keypad (IR or wired), the keypad's protocol (A or B)
might not match the projector's IR protocol setting. Refer to section
2.3, Hardware Setup for instructions on how to check and change the
keypad's protocol setting. However, if the projector's setting is "Off",
the remote keypad will not respond. You may have to configure the
keypad for built-in operation to gain control of the projector.
Symptom: The projector will not turn on when is pressed. One or more of the
following red LEDs are lit: ERROR, LVPS, EHT, H.FAIL, V.FAIL.
Cause/Remedy: 1) An internal failure has occurred. Projector servicing may be required.
Contact your dealer or Madrigal for assistance.
Symptom: The projector's green POWER LED is lit and all other LEDs are off yet
no picture is displayed.
Cause/Remedy: 1) Contrast or brightness may be set too low. Press to activate the status
screen. If there is no display, press then increase contrast ( ) and
brightness ( ) until the crosshatch is displayed. Adjust contrast and
brightness to their proper settings.
2) The room lighting may be too bright.
3) The projector may be too far from the screen. Move the projector closer
to the screen. The maximum throw distance is 25 feet.
4) Were the lens covers accidentally left on? Remove the lens covers.
Symptom: While in use, the projector suddenly become non-responsive to keypad
commands, even when using a built-in keypad.
Cause/Remedy: 1) Although rare, it is possible that an internal software error occurred
which has put the software in a non-ending loop. This might occur if
a power spike interfered with the projector's internal processor system.
To fix this problem, leave the projector plugged in and using a small
screw driver or ball point pen, press the recessed RESET button on the
back panel. This operation will reset the projector's processor without
affecting memories or display settings.
