additional information. To contact HP, refer to the support guide included with the projector.
Warning light problems
If both red warning lights are blinking:
• Allow the projector to cool down after it turns off. If this condition occurs after you
restart the projector, an internal component has failed. Contact HP for assistance.
If the red temperature light is on or blinking:
• Allow the projector to cool down after it turns off. Be sure that nothing is near or
blocking the vents on the projector, and that the vents are free of lint and other objects.
Remove any sources of excess heat in the room. Observe temperature and altitude limits
(see “Specifications” on page 55). If the warning light turns on or blinks after you
restart the projector, contact HP for assistance.
If the red lamp light is on or blinking:
• Allow the projector to cool down after it turns off. If the warning light turns on or blinks
after you restart the projector, remove and reinstall the lamp module.
• Install a new lamp. If this occurs after you install a new lamp module, remove and
reinstall the lamp module. If a new lamp does not fix the problem, contact HP for
assistance.
