If you see 'noise' or 'trash' on your Vizio HDTV screen, it may be due to up-converting a digital broadcast signal that is exceeded by your HDTV’s digital capabilities. If you are using an antenna, the signal strength of the channel may be low. Make sure your antenna is connected securely to the TV and move the antenna around the room or close to a window.
What causes distorted picture or unusual sound on Vizio HDTV?
Distorted picture or unusual sound on your Vizio HDTV can be caused by interference from electrical appliances, cars, motorcycles, or fluorescent lights. If you haven't mounted the TV on the wall, try moving it to another location to see if this resolves the issue.
Why does my Vizio M420NV have abnormal patterns on the picture?
If your Vizio HDTV shows abnormal patterns on the picture, check the connections of external devices connected to the HDTV. Ensure the specifications of external devices meet those of your HDTV (like resolution). If you are using an antenna, the signal strength of the channel may be low. Make sure your antenna is connected securely to the TV and move the antenna around the room or close to a window.
