InFocus MaxFlight MT3000(B) - Manual (Page 74)

Computer and Monitor power flows from the wall to the command console UPS (battery backup). The
surge protect side of the UPS powers up the lower right power strip this in turn powers up the Pre-
Amp, Main Amp and cabinet fan. If the GREEN power on light does not come ON solid when UPS is
turned on then there is no power getting to the UPS from external sources.
5-7B No Computer Power
Is the monitor ON? Is the UPS ON? Is the power strip in the lower part of console ON?
If the computer is not powering up, check the drive lights. If no drive lights, check the power ON
switch at the lower left rear of CPU. If OFF, turn it ON. If UPS green ready light is not ON, try
another extension cord from a known good power source and plug UPS into this. Still no green light
when turned on, check the reset at back of UPS if out push in if power returns OK. If not, it is a bad
UPS. Plug computer and the rest of the components into the power strip. Power the strip with good
extension power if all works OK replace the UPS.
Everything powers up except the CPU, this is usually a bad internal 300 watt ATX Power Supply.
This 300-watt power supply can be purchased at any computer or electronic supply store. Do not
remove the old until the new is at hand so you can match the connectors.
NOTE! Before touching any board or other internal component in the CPU you MUST ground
yourself to the CPU cabinet (metal) to discharge any static electricity that your body has. This will
prevent you from damaging expensive circuit boards etc. Make sure that all the board /components
that require power have the proper plug installed. Replace the audio feed cable from the CD-ROM to
the audio board.
5-7C Cockpit Power
Turn cockpit power ON by pressing the toggle switch on the power strip located behind side ABS left
side. This powers up the following; cockpit ventilation fans, projector power, projector vent fan and
power strip located behind lower ABS dark panel right side under seat. Power flows from the wall to
the strip, through the signal slip ring left side pitch shaft, to the center weldment where it connects by
plug to the, roll ring then the output from there plugged into the power strip. Make sure everything is
plugged into the strip correctly and the power strip is turned ON. To test, use a meter and test at
cockpit power strip, then input plug which is the output side of the roll ring, then center weldment
connection plug which is the pitch ring output side and finally the power strip itself. If you have power
at the input of a component but not the output, then that component is defective.
5-8 Video Problems
See owners’ manual for detailed maintenance instructions and warranty information. All electrical
units use the “INFOCUS” LP-400 series projectors. Signal flows from the CPU VOODOO 3DFX
card, via cable to the pitch ring left side, to the center weldment interconnect, to and through the roll
rings, to the projector input side. Should be a VGA signal. Going into the S-Video connector on the
projector.
5-8A No Image
Check that the power plug is all the way connected on side of projector and switch right above
connector is turned ON, backlight on the front control buttons comes on if power is available. Check if
the vent fan is running. If so, check that the projector plug is plugged into the lower right power strip
below cockpit seat. If power is there but projector does not turn ON then you have a bad projector.
See warranty. If there is no power at the strip see cockpit power.
5-8B Image
If after power turn ON you still do not have test image you probably have bad projector bulb. Replace
it with one from factory or Maxflight. Replacement procedures are in owner’s manual.
