Kramer Electronics TP-1xl user manual Video Signal, To solve the problem perform the following

13.2 Video Signal

Problem	Remedy
No video at the output	1.	Confirm that your sources and output devices are powered on and connected properly.
device	2.	Confirm that all devices in the signal path have the proper input and/or output selected.
	3.	Try to invert polarity, using the polarity switch (TP-12N, 704, 708 Only).
	4.	Use a Video Tester to examine the video path leading to/from your Twisted Pair
		Interface /Kramer Tool (see section 3.2 " Video Tester")
Video level is too high or	1.	The Twisted Pair Interfaces/Kramer Tools in this manual (except for the TP-1xlTP-6,
too dim.		TP-11N, 705, 707, 709, 711, 712) offer termination switches on each input. Verify
		that the twisted line is well matched, otherwise it results in a video level that is too
		high or too dim when looping is performed and the termination switches are not in
		proper position (see section 11.2 for more details).
	2.	Confirm that the input and output connecting cables are of high quality, properly built
		and terminated with 75 ohms.
	3.	Check level controls located on your source input device, output display, or recorder.
Signal quality degradation:	Inappropriate cables usually have excessive built-in capacitance. When long shielded
color is fading or smeared,	cables are used the capacitance grows, and the cable collects more interference from RF
quality of the picture is	sources, such as transmitters, computers and other appliances creating RF fields. At the
reduced, details of the	same time the cable also impedes the streaming of high frequency signals. As a result of
picture are lost.	this interference, and of the high frequency loss, signal quality degrades.
	To solve the problem perform the following:
	1.	Use high quality, non- shielded cables (UTP type) for the longer distances (Multi
		Twisted Cable Wire is recommended).
	2.	Use a line amplifier from the TP series (such as the TP-6) to pre-compensate for
		signal degradation. You may cascade several line amplifiers to extend the range.
		Connect the line amplifier as close as possible to the video source.
