Chapter 9 Maintenance and Troubleshooting
Cleaning the TV and Remote Control
1.Remove the power adapter cable from the TV.
2.Use a soft cloth moistened with diluted neutral cleaner to clean the TV and remote control. VlZlO recommends using an HDTV cleaning solution which can be purchased at any major retailer.
3.Wring liquid out of the cloth before cleaning to prevent water from penetrating into the housing.
4.Wipe the TV and remote control with a dry cloth after cleaning.
•Do not use volatile solvent (such as toluene, rosin and alcohol). Such chemicals may damage the housing, screen glass, and remote control, and cause labeling to peel.
•The screen glass is very fragile. Do not scrape it with any sharp object.
•Do not press or tap the screen to avoid cracking.
