Warning Light Problems
Startup Problems
If both red warning lights are
blinking
• Allow the TV to cool down for about three minutes after it turns off. If this
condition occurs again after you restart the TV, an internal component has
failed. Contact HP for assistance (see “Contacting HP Technical Support” on
page 67).
If the red temperature light is on
(right of the blue light)
• Allow the TV to cool down for about three minutes after it turns off. Be sure
that nothing is near or blocking the vents on the TV 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 71). If
the warning light turns on after you restart the TV, contact HP for assistance
(see “Contacting HP Technical Support” on page 67).
If the red lamp light is on (left of the
blue light)
• Allow the TV to cool down for about three minutes after it turns off. If the
warning light turns on after you restart the TV, remove and reinstall the lamp
module.
• Install a new lamp module. If this occurs after you install a new lamp module,
remove and reinstall the lamp module. If a new lamp module does not fix the
problem, contact HP for assistance (see “Contacting HP Technical Support”
on page 67).
If the red lamp light is on and the
red temperature light is blinking
• If the temperature light is blinking two times repeatedly, allow the TV to cool
down for about three minutes after it turns off. Be sure that nothing is near or
blocking the vents on the TV and that the vents are free of lint and other
objects. Contact HP for assistance (see “Contacting HP Technical Support”
on page 67).
• If the temperature light is blinking three or more times repeatedly, contact HP
for assistance (see “Contacting HP Technical Support” on page 67).
If no lights or sounds turn on • Be sure that the power cable is securely connected to the TV and the other
end is plugged into an outlet with power.
• Press the power button again. Try the power button on the side of the TV. (If
the button on the TV works, but not the button on the remote control, see
“Remote Control Problems” on page 64.)
• Unplug the power cord for 15 seconds, then plug it in and press the power
button again.
• If you recently installed a new lamp module, check that the lamp cover is
correctly installed.
