5 Fixing Problems
Maintaining the Television
The television is designed to require very little maintenance. For best performance, keep the television clean, and
replace the lamp module when the television displays a warning message.
Cleaning the Television
Keep the television clean as follows:
• Keep the television in an area free from excessive dust and dirt. You cannot clean any of the television’s
internal surfaces.
• Wipe the screen and case with a soft, dry cloth. Do not use water, polish, solvent, or other substances.
• Use a vacuum cleaner to clean dust from the air vents on the back and sides of the television. Do this at least
yearly, or more often if there is visible accumulation.
Forgotten Passwords
If you have parental controls set on your television and forget your password, turn off the television. Then press the
following sequence of six buttons on the remote control:
Menu , 000, OK, power. This allows access to the Lock menu
without entering a password, but only until you turn off the television. You must create a new password before you can
change lock settings or view blocked programs.
Replacing the Lamp Module
As the television operates over time, its lamp module gradually becomes less bright and more susceptible to breakage.
You can install a new lamp module anytime to bring the television up to factory-fresh brightness. We recommend
replacing the lamp module after approximately 6000 hours of service.
HP replacement lamp: L21 14A
CAUTION: We recommend that the lamp be exchanged at or before the end of the lamp’s rated life
— 6000 hours of use — because after that, the risk of the lamp rupturing could increase.
High-temperature glass fragments from a ruptured bulb can cause injury, fire, or damage
to property.
CAUTION: Replacing the lamp module requires special considerations:
• Carefully read the complete instructions for “Replacing the Lamp Module” in this Section 5
before replacing the lamp module.
• To reduce the risk of injury, use extreme care when removing the lamp module, because
broken glass might be present.
• The lamp contains a small amount of mercury. If the lamp breaks, adequately ventilate the area
where the breakage occurred, discard any nearby food and drink, and thoroughly clean the
table surface around the television. Wash your hands after cleaning the area or handling a
broken lamp. Disposal of this lamp might be regulated because of environmental
considerations.
