[QUOTE="garyjs, post: 506527, member: 33538"] Hi - new to the forum so apologies if not following the correct approach. I had a physical fault on the video unit at my front gate and replaced the unit but somewhere in the process I seem to have disturbed some wires, or done something else that meant it didn't work. Looking for any ideas or suggestions? I have taken the system apart and indoors out of the cold and even now can't get video to work. It is a CCL-VC2-CK door entry intercom connected to a MT320C-CK colour monitor. What I think should happen- which may be wrong - is that when the call button is pressed the V+ line activates and switches the camera on. But it doesn't! That line is staying at around 4.6v and not switching up enough to activate camera. If I put 12v straight into the camera, it powers up and I can see video but it stays on (LEDS remain lit even when monitor shuts down). Could something have "blown in the monitor" if the wires were mixed up during removal/refitting? Also - in the house there were two monitors and there seems to have been some jumpers put in to short some of the pins at the rear of the monitor because it was in a two monitor configuration - could that be the issue? Any idea what the configuration should be? Once again apologies if not the right forum for this type of thing and I'd appreciate any ideas? [/QUOTE]
