I just bought a soldering iron! Answered

   So im new to the soldering world as well as the small electronics and circuit world. I do know a little about restance capacitance and inductance. But I was wondering if anyone had any good ideas for me to get started off with. I have an old TV, Im not sure if I can use my soldering iron to de-solder it, that I can strip down for parts.  
   My new soldering iron is  a 20w to 40w, Im not sure what range I need though. If anyone knows any fun easy DIYs that I can do to get started please let me know!!  Thanks!

 Should be perfect for electronics soldering.  Do you have a solder sucker or soldering wick to help you desolder? And a little clip to use as a heatsink when you solder/desolder IC chips?

If you plan on gutting out an old CRT tube type TV, look up how to safely work around the capacitors and the tube that still have a lethal charge in them.  Be careful.

Thanks for the tip on the capacitors, I kinda had that in the back of my mind but wasnt sure if it would be a big deal or not. And no I do not have a sucker or a wick, do I need one? Or could I just use the iron to losen it up?  And as for the heatsink, why do I need it? And what is an "IC chip" ?

When you desolder, you want to remove that blob of old solder.  You just can't smear it away and leave a nice clean hole or component lead.  Also, if there is too much solder or you want to start over on a clean joint, you need to suck or wick away the excess solder.  With many components, if you desolder one lead, it will stick again in the hole if you don't remove the solder as you work on the other lead.

Integrated circuit chips and transistors or other complex components can be damaged by too much heat.  A little metal alligator jaw or smooth jaw clip clipped on to the lead before it runs into the component will draw away the heat and somewhat protect it from excess heat.

You will find that you might need a good pair of needlenose pliers or tweezers to help. A "third hand" jig(many instructables on this to search for) to hold the board steady, a brightly lit work area, and a wet sponge to wipe the dirty tip would be handy.  Lots of good beginner or simple LED projects to start on.  Have fun.
