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. VIZIO
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.
Important:
Do not use volatile solvents (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.
Troubleshooting Guide
If the TV fails or the performance changes dramatically, check the display in accordance with the
following instructions. Remember to check the peripherals to pinpoint the source of the failure. If the
display still fails to perform as expected, contact the VIZIO for assistance by calling 877-MYVIZIO (877-
698-4946) or e-mail us at

Make sure your AC power cable is securely connected to the back of the

Plug another electrical device into the outlet to insure the outlet is working

Try another electrical outlet elsewhere in your home. Preferably on a different
circuit.
Try another AC power cable. Any standard 3 prong, grounded, UL approved
computer power cable can provide power to your television.
