Others have spoken about the liability so I'll just speak to the sheer
irresponibility of perfoming unauthorized repairs on a peice of
life-safety equipment.

Then again, for someone who is prone to trying to repair a board rather
than replace it, my guess is you would more attentive to the money it
would cost you rather than the lives you are risking.

If a board has proper power applied and all the appropriate inputs but
does not generate appropriate responses then the board is bad.  What
more do you need to know?  Replace it.

Or would you truly be comfortable looking into the eyes of someone who
lost a loved one due to your cobble-job and telling them, "Well, it was
cheaper to do it that way, and it seemed to work okay..."

For fuck's sake, do the job right or get another job.
