I'm attempting to locate a problem on my Dell D1025TM UltraScan
(Trinitron) monitor. I posted about it a week and a half ago. I got
the D board out and am checking for bad solder joints.

I'm not sure if these should be re-soldered or not. If so, what's the
best way to get the crud off the pads and surrounding areas? Will
acetone do it?

Is the residue rosin that has seeped out of the solder itself as a
result of thermal cycling over a period of years? I notice that all of
these solder joints are for components that get hot while the monitor is
on.

I realize there may be other cold solder joints that don't appear to
have anything wrong with them at first glance, unlike these, but these
got my attention first. I realize these may not be "cold" at all.

Appreciate any and all comments. Thanks!

FWIW, they look fine to me. I'd look elsewhere for the problem.

I wouldn't worry about the rosin unless you're in an extremely high
humidity area, and maybe not even then.
