Beh,
Welcome! to the Group.
You have followed very practical approach for investigate the problematic area by connecting external supply & checked whether rest of the stage working properly or not before spending time for repair this will gives clear idea still how long you have to go.
Once you understand the fundamental working of Power supply Circuit you will troubleshoot it easily & this circuit Tracing is possible in single layer PCB; in multilayered PCB it is very difficult to Trace the Circuit without Diagram like any motherboard where components are on both the side.

Now repairing any motherboard is very difficult without Microscope a must have tool.

Thanks! for sharing your experience.

Very well explained and nicely detailed repair Beh! And a successful one in no time was time well spent! I guess that the TVD-1035 display on the Taba intercom doorbell is black & white only, although the screen looks kind of bluish in the photo? Thanks for sharing!
