You are not at all thick. We all have to learn somewhere. The only time you
could be considered thick is if you never asked the question. :-)
The wiki/dictionary description of dry and cold joints describes slightly
different observable effects but to all intents and purposes a dry or cold
solder joint will produce the same result. Both usually result in a breakage
of the bond between the two components that are soldered. The simple
solution is to re-solder the joint using sufficient heat to melt the old
solder. You can either remove the old solder and apply new solder, or you
can add a little flux when you heat the joint. I would prefer to remove the
old solder and replace it with new flux cored solder. If you haven't done
much of this type of work, probably the easiest way to remove old solder is
with some "solder wick" which you can purchase for pennies on eBay. Place
the wick braid on the solder to be removed and apply a hot soldering iron.
The wick will soak up the solder and if it doesn't remove it all first time,
re-apply the wick a 2nd or 3rd time.
One thing you ABSOLUTELY MUST do before you start ANY work inside your rig,
is to observe ANTI-STATIC precautions. Use a wrist strap specially made for
the job and preferably use an anti-static mat. DO NOT EVER connect yourself
directly to any anti-static ground source - you could DIE!
