If it's not the AC adapter, I have a feeling it's the "left IO board", i.e. the daughtercard on the left side which contains the DC-in. This is responsible for all power-related functions, and if two boards and not worked with the same DC-in, I'd say replacing the IO board/DC-in is the next step. Here's the iFixit guide for replacement of that board:

Actually, it's inlikely, but now that I think about it, it could also be the topcase and power button as you mention, although the power button rarely goes bad. You said the board was professionally installed...didn't they test it once they did the work on the machine?
