I agree.
I hoping, for example, that someone knows a good way to "reset"


Crying out loud!!! Find a reset or master clear pin on the micro
processor chip and jumper it to ground for few seconds... reset done.
Is it so difficult for you? You are just mouth, where is your brain and
hands? Where is the pin number? Look up the chip data sheet...


the alarm system board, which might just be the problem.

I often find problems using just my eyes and my nose.


Agreed. I see the burnt leads to the cap with my eyes; and I smelled
the burnt transformer with my nose.

I use a small flashlight or my lighted magnifying glass to look to
look for cracks or loose components on a circuit board.


I agree; the best initial diagnostic is a good set of eyes going over
every inch of the board!
