Symptom
Black screen, blue screen, "no picture", "nothing", snow, fuzz.

Cause
Black screen could be related to a video problem, the TV is not powered on or plugged in or a black screen with banner issue after the banner has gone away. Do not confuse the No Signal message with the message from the receiver. Video issues could be a receiver not powered on, the TV or VCR is not tuned to the correct input or channel, bad cable, disconnected cable or incorrect cable connection.

Prevention
You can avoid video issues by ensuring all of your equipment is powered on and set to the correct video source. Properly installed quality cables will prevent future problems.
