13.2 Video Signal Problem No video at the output device Video level is too high or too dim. Signal quality degradation: color is fading or smeared, quality of the picture is reduced, details of the picture are lost. Remedy 1. 2. 3. 4. Confirm that your sources and output devices are powered on and connected properly. Confirm that all devices in the signal path have the proper input and/or output selected. Try to invert polarity, using the polarity switch (TP-12N, 704, 708 Only).
Problem Remedy Noise bars are "rolling" up or down in the output image or: Low frequency Hum in the output signal Hum bars (ground loop) are caused by a difference in the ground potential of any two or more devices connected to your signal path. This difference is compensated by routing that voltage difference through any available interconnection, including your video cables.
