abayomi 0 Posted September 14, 2016 Hello everyone, please excuse my frustration. I have researched everything and am beyond frustrated with no answers. I have a QSee 908 DVR with 5 wired in cameras which are all hooked to our Samsung smart TV through a VGA cable. Everything views fine with the security cameras UNTIL.... I attach my shaw PVR HD digital box! When I attach the HD PVR with the HDMI cable to my samsung TV (without the coaxial cable attached).. The security cameras are fine... It's when I even touch the coaxial TV line to the coaxail in on the HD PVR is when all 5 of my security cameras go crazy with lines! If I use the source button to go to the HDMI output, the TV channels are fine but when I change the source to the VGA connection, the security cameras are going crazy! I have even tried attaching the DVR to the TV with an HDMI cable and the same thing happens. Which means I am not able to leave my HD digital PVR plugged in without unplugging my security cameras (DVR)!! So we can not use the PVR to tape or watch TV shows! Researching I was reading some about EMI interference and Ground loop issues... Not sure what is going on or if I am ever going to be able to have both plugged in with without interference on the security cameras!! I'm feeling overwhelmed! Qsee says it's a TV issue, samsung says it's a DVR/security camera issue and shaw cable says it's not anything to do with them. Can anyone offer any information? oh! I would be extremely appreciated! Time for a glass of wine to calm my nerves! Thanks so much Lisa Share this post Link to post Share on other sites
