i was folow developing of case you got....i am hobbist to and from my
experience i can tell that malfunctions caused by "cold solder" are most
dificult problems to solve...especiali when there is some random states of
working and it doesnt working...and again...and again...but you cant see it
where does it happening...

even tracking signals is sometimes waste of time...even method of searching
cold solder in dark room (so you can see the sparking place)...seems
sometimes is pure luck that matters! )
