new to forum, could use some advise.
my house has cat 5 wiring for hdmi video from a sat receivers to my tv sets. everything works good, but it get a video 'flicker' when turning on a ceiling fan, the furnace turns on, or certain electrical items are plugged in to a third household circuit. 3 circuits cause this issue, i have tried the obvious, relocating electrical cables to about a foot away, but same problem. the only thing left is that the 3 circuits causing the issues run parallel within inches of the main support steel i beam. can emi be strong enough to be inducted into the i beam? would that be amplified enough to case 'flickering'? if so, can simple grounding of the beam fix this?
thanks
