Yeah, I did... well, I didn't have new ones but did have spare ones from
a third 'parts' board. I desoldered a bunch, and took the best three
for Q201, 202 and 203. I did notice some of them had gotten some stress.
Maybe I should remove parts further down the line and just test that way
without a load?
Guess if NOTHING else works I could just start swapping parts between
the X and Y axes, but it's really tough to work on the monitor without a
test rig (it has to be fully disconnected, moved, and reconnected for me
to do any soldering alterations it) I was hoping that I could quickly
zero in on the problem with a scope and a VOM but here we are after
three days and I'm still scratching my head. *sigh*
