The image flickers, goes in and out, or there is snow like affect, there are multiple reasons for this is-
sues. Check all the connections HDMI and CAT5E/CAT6 and make sure they are fully connected and
are not loose. Check to see the CAT5E/CAT6/CAT7 terminations are fully crimped. CAT5E/CAT6/CAT7
is pick¬ing interference from other cables in the wall. Shielded cables are recommended to be run in
the walls. CAT5E/CAT6/CAT7 wall plates or CAT5 terminal blocks should not be used as they can also
cause inter¬ference in the signal; it needs to be connected with cables direct. The CAT5E/CAT6/CAT7
cables should not exceed the distance they are meant to be run at. It is important to use T568B termina-
tion on the CAT5E/CAT6/CAT7 cables.
