Verify that all video cables between the DCX3501-M and the TV are firmly

If the DCX3501-M video output is connected to a home theater unit, verify that

the home theater unit is powered on and set to the appropriate input source.
If the DCX3501-M video output is connected to a TV through an HDMI
•
