 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 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  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.
