kevinkwt14 0 Posted December 5, 2018 I have installed a system but unfortunately the Display on the TV goes blank after a few hours but at the same time DVR HDD and camera are working only not able to view the camera output but when I remove the power supply and put it back on the DVR the output comes back but again after sometime it goes off again. I have being trying to contact the service support everything but no use. Share this post Link to post Share on other sites
