keithy 0 Posted November 25, 2018 Hi have a qyis nvr it has worked fine for 8 months but this week the output to the tv has become jerky switches off and is full of interference. I have swapped the hdmi cable, changed tv's the picture is still the same. When viewing with the app ton smartphone the picture is fine. Anyone have any ideas ?

tomcctv 190 Posted November 25, 2018 Hi. Do you only have 3 cameras ? It also looks like a image output problem as the 4th camera not showing also shows the problem on a blank screen. Can you switch off your NVR and disconnect the hard drive .....then see how image is without. Share this post Link to post Share on other sites
