I am trying to fix a Plus AB.

I am sure is on the AB side, changing it solved the problem.

Apart from the usual re soldering connector, what are the weak spots ?

The Plus didn't make any sound nor any screen activity with the old AB.

Power Switch?

Sometimes the switch fails, you should test continuity on that switch.
