Have you ever been on Craigslist or maybe a similar classifieds website? You probably answered yes just like most people who use the internet. In this case you have probably seen a lot of free or dirt cheap t.vs and other electronics, maybe even a very expensive 1080p LCD t.v, but it has something wrong with it.
Well in many cases you can fix these quite easily. I once bought a very nice LCD t.v for only $25 that would freeze when you finally got the picture working or hardly ever turn on at all, I was able to fix it just using a $10 soldering gun from Walmart. The solder joints had decayed to the point they weren't working properly, I spent maybe 2 hours learning how to solder and actually doing it.
I did some research on the t.v and found that refurbished ones were selling for almost $1000, I sold mine the next day for $700!
Sometimes these things can be kind of rare, or you can just make a 665 dollar profit on it. However, you can still find plenty of opportunities like this just waiting for someone to find. Give it a shot, look around, see what you can stir up!
Here is a quick and simple soldering guide if you are interested.
First, you need a soldering iron (around 25W for fine work and about 50-80W for connectors anc coaxial cable), 60/40 solder and a soldering iron holder. It pays to invest a bit more into a reliable good quality soldering iron with suitably fine tip for fine work. Adjustable temperature is a plus here as you can use the same iron for fine work and more robust cabling etc. Be careful not burn up anything. The soldering iron is extremely hot so DO NOT touch the metal parts of the soldering iron! Also, try not to breath the fumes from the solder. Work in a well ventilated area. Before you solder, you must tin the tip. Simply wait for the soldering iron to heat up, apply a coat of solder on the tip, and wipe it with a wet sponge. Now, to solder the components onto the board, cut the leads at the proper length. Stick the component's leads through the proper holes and bend it so that It'll stay still. Put the soldering iron tip so that it's touching the lead and the copper at the same time. Then apply the solder on the lead (not on the tip of the soldering iron). Let the joint cool by itself. PRACTICE A LOT!
A small tip: Whenever you remove insulation from a wire, apply a coat of solder to the exposed end. It will be much easier to handle after that.
