Hi..
view of your statement, I believe your problem is the projector lamp. to make sure they try to do troubleshooting on your projector.
1•Make sure the lamp has not been in use for over 2,050 hours.
The lamp automatically shuts off at 2,050 hours and the LED
blinks orange.
2•Check the projector's lamp to ensure that it is securely connected
in the lamp module. Make sure the lamp door is
installed.
Replacing the Projection Lamp
WARNING: To avoid burns,
allow the projector to cool for at
least 30 minutes before you open
the lamp module door. Never
extract the lamp module while the
projector is operating.
The lamp hour counter in the Status menu counts the number of
hours the lamp has been in use. After 2,000 hours of use, the message
"Change Lamp" temporarily appears on the screen when
the projector is turned on. Change the lamp within the next 50
hours. After 2,050 hours, the LED flashes orange and the lamp
will not light. You can order new lamp modules from your InFocus
dealer. See "Accessories" on page 42 for information.
Follow these steps to replace the projection lamp:
1 >Turn off the projector and unplug the power cord.
2 >Wait 30 minutes to allow the projector to cool thoroughly.
3 I>nvert the projector on a soft flat surface, then insert a small
screwdriver or other flat object into the tabs on the lamp module
door and gently pry the door up.
4 >Pull the lamp door up and remove it.
5 >Loosen the two non-removable screws on the outside of the
module
WARNING: Be extremely careful
when removing the lamp module.
In the unlikely event that the bulb
ruptures, small glass fragments
may be generated. The lamp
module is designed to contain
these fragments, but use caution
when removing the lamp module.
CAUTION: Never operate the
projector with the lamp door open
or removed. This disrupts the air
flow and causes the projector to
overheat

manner.

lamp module or touch the glass
bulb! The glass may shatter and

7 >Install the new lamp module, being sure to align the connectors
properly.
8 >Push the module in until it is flush with the bottom case of the
projector.
9 >Tighten the screws on the outside of the module.
10 >Replace the lamp door by inserting the hooks on the lamp
door into the slots on the projector and pressing the lamp door
into place. If the lamp door does not fit properly or bulges out,
remove the door and re-seat the lamp module.
11 >Plug in the power cord and press the Power button to turn the
projector back on.

and hold the volume - button, then press the menu button
