Soldering.

.... allow the solder to flow......

Solid advice mark, make sure it flows, you can solder all you want and still not get a good contact. so desolder, clean, before you start.
Here are some good pictures:

You may need a de-soldering pump to get the old solder off the board before inserting the new wire.

I perfer solder wick myself ... but if you have the board out you can just heat the solder up and then whack the board on the table (c:

if the wire just came loose, then you should just be able to heat up the sauder and keep the iron touching it as you place the wire in the puddle. then remove the iron, let it cool, then let go of the wire. simple.
if you want it to look prettier, use a sauder wick. its a braided copper thingy. then re-do the whole joint.

why does everyone thing the cold heat is crap? i've got one, and find it alot easier to use than a standard iron. no worrying about burning yourself or whatever you set it on, no cord to deal with, no accidently melting your project; and its almost fool-proof. and it actually works great on electronics. i used it to fix my friends warp feed and re-do the saudering on the battery harness on mine. the joints i did look better and are alot cleaner and also hold stronger than the origional ones.

My personal opinion is that there isn't enough mass in the soldering iron to hold in heat. Maybe if I only soldered something once in a blue moon that cold heat thing might work for me, but I solder all the time. Since Saturday I've gone through a roll of solder already. There's a zen to it man ...

Isn't sauder a partial board furniture company?

The best thing thing to do is just practice. Like I first said, Soldering is an art.

Marks advice is good, but I wouldn't tin or solder the wire BEFORE sticking it through the board. You may need a de-soldering pump to get the old solder off the board before inserting the new wire. Keep the solder to a minimum, as loads of solder tends to heat up real fast and ruin components.

Yeah I forgot about the desoldering the hole bit...trouble is it comes as second nature to me so it makes a little more difficult to write down the steps but I do have to disagree with you saying about not tinning before putting through the hole, this will make for a messy joint as you will have to solder from the reverse and definitely add solder instead of tidying up on the reverse plus the lack of solder in the wire will possibly draw way too much solder into the wire and in turn often overheat the insulation and then things start to get real messy. When soldering surface mount switches and the like then yes I agree but wires going through, no always tin before.
