Chapter 5 Maintenance and Troubleshooting
5.1 Maintenance
Important
1. Make sure that the power cable is removed from the socket before cleaning the TV.
2. Do not use volatile solvent (such as toluene, rosin and alcohol) to clean the TV. Such
chemicals may damage the housing, screen glass and remote control, and cause paint to
peel.
Cleaning the Housing and Remote Control
1. Use the VIZIO soft cloth (included) for cleaning.
2. If the housing or remote control is seriously contaminated, use a soft cloth moistened with
diluted neutral cleaner to clean the display. Wring water out of the cloth before cleaning to
prevent water from penetrating into the housing. Wipe the display with a dry cloth after
cleaning.
Cleaning the Screen
1. Use the VIZIO soft cotton cloth (included) to gently clean the screen.
2. The screen glass is very fragile. Do not scrape it with any sharp object. Do not press or tap
the screen to avoid cracking. When the screen is seriously contaminated, use a soft cloth
moistened with diluted neutral cleaner to clean the display. Wring water out of the cloth
before cleaning to prevent water from penetrating into the housing. Wipe the display with a
dry cloth after cleaning.
