bkm97423 0 Posted February 28, 2017 I installed my 4 infra red cameras & they worked great. For some stupid reason I went into the menu & changed the resolution. The dvr restarted & now all I get on my monitor is a blue box saying "OUT OF RANGE 55.9KHZ/60HZ" I google searched the problem & it said remove DVR cover & push black button to reset to default settings & reboot system. Well I cant find any button anywhere & tried unplugging HD & it did NOTHING! PLEASE HELP! I'M STUCK WITH NO VIDEO FOR CAMERAS! Share this post Link to post Share on other sites
