gillabis76 0 Posted April 1, 2016 Hi Guys, Good day. I've googling for how many days now looking for a schematic diagram of cctv camera, i am trying to understand how camera works before i attempt to repair my 16 cameras, all have the same problem. WITH POWER BUT NO VIDEO i can tell that it is powering because the LED is lighting up when i cover it. can anyone pls help with this, i cant proceed without understanding fully the step by step process of the camera and if any of you guys have a tutorial or video in repairing cctv cameras, i would really appreciate it. Thanks. Gil CCTV Tech. Support Philippines Share this post Link to post Share on other sites
Securame 0 Posted April 1, 2016 Well... If 16 cameras do the same, I will take a guess; the cameras are fine, the problem is with the power supply. The fact that the led lights up does not mean that it is supplying the right voltage. Share this post Link to post Share on other sites

aibudo 0 Posted April 9, 2016 Following up with tomcctv's last comment/question. Did you replace the original DVR with a new one? Have run into this when the camera's are a different format than the DVR. Have also had an issue where the DVR fails and video is no longer processed. If the camera's are standard analog, then hook one of them up to a TV or monitor with a video (yellow) input jack and see what the response is there. If the camera's are of the HD analog type of SD/CVI/AHD or TVI, then the TV/monitor won't process the video. Give us more info as to the make/model of the camera's and DVR.
