Why are no images displayed on some or all of the channels of the Q-See QT DVR?

If no images are displayed on some or all channels of your Q-See DVR, there could be a connection problem. Check the cables and ports of the camera and DVR. It could also be a camera problem; try attaching the cameras directly to a working port on the DVR to check them. Another cause may be that the video format (NTSC/PAL) of the DVR is different from that of the cameras. If this is the case, change the DVR video format.
