hope you are also able to read and write in english, but for any support in Deutsch I would also appreciate very much, I can read well, but cannot write yet
ok, what has happens? after some time the camera started to show the picture only in Black and White format, like it switched to night mode completely, but in the same time the IR LED doesn’t work. First I checked the new firmware and reset all settings - it didn’t help. Then I opened the camera and started to inspect circuits. First I checked the IR LEDs and all of them are fine, the light sensor also in good condition. I have found on the small PCB which is responsible for the IR light the connector where should come 12 volt, but there is only 2.5V. I disconnected the incoming power, checked it and it has 12V, thus it means something consuming almost all energy in this PCB and in the same time doesn’t run the IR LEDs. When I disconnected the power I heard a „click“ in the objective, and then I started to see normal colorful video. I assume that something has happened with this small PCB and it sends to the camera signal that already night(thus camera is switching itself to BW mode), and in the same time consuming all energy but not switching the IR LEDs ON.
If you have any ideas, or at least the circuit diagram which I can use for troubleshooting what is going on there, I would much appreciate it.
Thank you all for your support in advance!
