Repairing video doorbell

[vrijebaxx]

Hi all.

I am having issues with my door bell. Recently I was moving to new apartament and during this I was transfering and rewiring the video doorbell. But unfortunately I made wrong connection. The 12 VDC was done in red square insted of green on picture.
Visually all components looks good, so I could use some help where to start with troubleshooting and repairing.
The unit is now just with light on with no response.

Nothing useful is said about the connections or logic diagram but it appears you connected 12V to an output switch rather than the input, so it is hard to imagine what is damaged, but know that damage is possible.

Yes, it looks like that.

Unfortunately I don't have any diagram (it was very hard to find even maker of this device)
