Correct. Now examining PCB with magnifying glass and continuity tester to
inspect circuit line that may look broken or brownish as earlier described as
evidence of corrosion.
Common sense, patience and willingness hoping for dumb luck.
Never surrender!

@Brian we disagree.
Noted.

So the screen/kb from the unit you were working on worked fine on the other
M100? (Just making sure.)

I think this is a discussion best had off list
Regardless of whether I agree with the rules or not. Intentionally antagonising
John by posting a response that blatantly disregards the list rules on cussing,
which he has politely ask all to respect. Is also probably not the best way to

I'm sorry, I thought I was responding off-list, because John's email said
"off list" in it, and I didn't look carefully when replying.
I stand behind every word and I don't mind that it's public, but the list
didn't need to see all that, we were done with that and I do believe in

Of course I did it again, because I did nothing in the first place, or any
subsequent time.
You are in the wrong. Adjust what you consider harmful into something more
in tune with reality, and yes apologize for getting it a little wrong.
You can in fact do that. whatever weird internal list of
Thanks. Dug out another Model T and swapped screens and keyboard.They worked
flawlessly as suspected.So the LCD and keyboard side of the equation has been
eliminated.

Unfortunately that is a pretty typical solder joint for an M100 it is OK.
One thing you might want to look for is corrosion caused by flux residue
that was left behind after the manufacturing process. It looks like a
copper brown deposit but might hide a damaged track. I have worked on a few
If you look close you can just see a green trace under that block of solder so
it looks like those two pins would be electrically joined anyhow. Sometimes
this PCBs had messy solder joints from the factory. Probably the most common
issue is a poor connection from the solder not flowing out
