Troubleshooting Guide - Vizio VU42L FHDTV10A User Manual

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.

has video that is many times better than old TV's and so you can see interference
and deficiencies you did not know you had.
