Maintaining Your Plasma or LCD TV

  • PrintPrint
This document pertains to HP Plasma and LCD Entertainment Displays.
This document explains how to clean and maintain your HP TVs. Refer to your User's Guide for complete information on safety.
NOTE:HP TVs ship with a protective film coating to protect the case of the TV during shipment and setup. If you have not yet removed the protective film, remove the film before cleaning.

Cleaning the Plasma TV screen

Use the following steps to clean the Plasma TV screen surface:
CAUTION:A special antiglare coating is applied to the screen of your TV. Using solvents such as alcohol or abrasive material such as a paper towel, may affect the screen coating or bezel paint. Do not use liquid or aerosol cleaners. Do not expose the TV to volatile gas or fluid such as pesticide. Do not put the TV in contact with vinyl or rubber products for a long period of time. Extended contact may result in the removal of the coating or degradation of the surface. Dropping the TV or forceful impact on the screen surface may cause the TV screen to break.
  1. Unplug the power cord from the wall (AC outlet) or surge protector before cleaning the TV.
  2. Use a dry, soft cloth to remove dust from the TV screen. Gently wipe the screen and avoid pressing on the screen.

Cleaning the LCD TV screen

Use the following steps to clean the LCD TV screen surface:
CAUTION:A special antiglare coating is applied to the screen of your TV. Using solvents such as alcohol or abrasive material such as a paper towel, may affect the screen coating or bezel paint. Do not use liquid or aerosol cleaners. Do not expose the TV to volatile gas or fluid such as pesticide. Do not put the TV in contact with vinyl or rubber products for a long period of time. Extended contact may result in the removal of the coating or degradation of the surface. Dropping the TV or forceful impact on the screen surface may cause the TV screen to break.
  1. Unplug the power cord from the wall (AC outlet) or surge protector before cleaning the TV.
  2. Use a damp cloth to clean the TV screen. Gently wipe the screen and avoid pressing on the screen.

Cleaning the TV case (not the screen)

For normal cleaning lightly dampen a clean microfiber cloth with water and gently wipe across the surface to remove dust or smudges.
To remove more stubborn contaminates, such as sticker residue, use rubbing alcohol with alcohol content of 50% or higher. Put a small amount of the rubbing alcohol on a microfiber cloth (such as a tissue). Gently rub the area a few times. The residue disappears and the rubbing alcohol evaporates in a few seconds. The rubbing alcohol does not harm the TV bezel or TV panel.
CAUTION:Please use rubbing alcohol with caution and follow all instructions on the rubbing alcohol bottle.

Tips for preventing image retention on plasma displays

A plasma TV illuminates phosphor to display images, much like a conventional CRT television. Viewing stationary images for extended periods of time results in uneven aging of the phosphor, causing images to permanently appear on the screen. Permanent image retention can be avoided by taking some basic precautions. The following recommendations listed here can ensure that your plasma TV has a longer life and offers better performance:
  • Whenever possible, avoid prolonged display of stationary images, such as Web sites, computer graphics, or video games.
  • Display video images in the widescreen 16:9 aspect ratio format. Use the Aspect button on the remote control to change from 4:3 screen size (what standard television uses) to 16:9 screen size to fill the screen. This prevents potential image retention of sidebars.
  • Avoid viewing the onscreen display (OSD) menus from DVD players, VCRs, and other components for extended periods of time.
  • When watching a movie from a DVD player or VCR, do not leave the same imaged paused continuously over a long period of time.
  • Turn down the contrast and brightness of the screen. High brightness and contrast can accelerate image retention or stationary images.
