if you don't know what normal operation is you're not really
troubleshooting, you're no different than a pig rooting for an acorn.
They often find the acorn but they also spend a lot of time rooting and
find nothing. 🙂

My earlier post was not intended as a "put-down" to anyone. My point is
that to troubleshoot anything, electronics or otherwise, you need to
know what "normal" operation is in order to identify a fault. Almost
anyone can troubleshoot anything if they know what "normal" is. Even
for a flat tire, "normal" is no leaks in the tube and the valve stem is
not leaking. Troubleshooting requires checking each to find the
problem. Troubleshooting an engine or computer gets a bit more involved
but you still need to know and understand "normal operation". In my
many Xerox training classes the course manual began each chapter on each
system in a machine with "Theory of Operation" that was read and tested
on before anyone went to the lab to troubleshoot equipment. Nothing
wrong with rooting as long as you don't do any damage. I've fixed a lot
of things that way but I wasn't really troubleshooting. 🙂
I started my career with Xerox working on their very first model, the
914, now in the Smithsonian museum , and ended on this one.

I worked on is also in the Smithsonian museum and my military uniforms
in the museum in my home town. I'll be in the museum soon myself.

P.S. The P.A. is set up at Mt.Vernon for the Gathering and details for
the Saturday evening event with the restaurant confirmed. Don't forget
to leave a note for the family so they know where you're at when you
come up missing in two weeks.
