Hi, I'm trying to set up some of these. I have three sets of them and had them all working fine when they were set up with 7' Cat 5 patch cables. I then put them in their permanent locations which involved about a 75' cable run. Two of them worked fine, but the third wouldn't show a picture. I've switched receivers and transmitters and have found this one receiver that won't seem to work anymore. I also notice that there is this green LED on the inside of the housing that is constant in the working units but is flashing in the non-working receiver unit. I'm assuming this means some sort of problem. Has anyone had any experience with this or have any thoughts to a solution.
Thanks for any assistance.
Eric
