5 Fixing Problems Maintaining the TV The TV is designed to require very little maintenance. For best performance, keep the TV clean and replace the lamp module when you see a warning message. Cleaning the TV You can keep the TV clean using the following recommendations. • Use the TV in an area that is free from excessive dust and dirt. You cannot clean any of the 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 TV. Do this at least yearly or more often if there is visible accumulation. Replacing the Lamp Module As the TV operates over time, the brightness of the TV lamp module gradually decreases and the lamp module becomes more susceptible to breakage. You can install a new lamp module at any time to bring the TV up to factory-fresh brightness. We recommend replacing the lamp module if a warning message displays. HP replacement lamp: L2114A WARNING! Replacing the lamp module requires special consideration: • To reduce the risk of injury, be careful 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 TV. Wash your hands after cleaning the area or handling a broken lamp. Disposal of this lamp might be regulated because of environmental considerations. For disposal or recycling information, contact your local authorities or the Electronic Industries Alliance at www.eiae.org. You can find safety information about the lamp at www.hp.com/hpinfo/globalcitizenship/environment/ productdata. • Because the lamp assembly operates at a very high temperature, turn off the TV and wait 30 minutes before removing the lamp module.
