I fix a lot of electronics by replacing the caps. It is really simple. You can visually see the bad caps. You flip the board, desolder the caps, put in a new cap, resolder and your done. There are a lot of good videos on youtube you can watch to see how simple it is.
I personally would not reuse caps, but you certainly can. There are a few problems with reusing caps. The first is that what is used in electronics from the manufacturer are junk. That is why they fail. These second is that caps/fuses are so cheap, it's not worth the time/effort to pull them off a board.
While you will find a lot of caps at Radio Shack that is the last place I would look. Your best bet is to order them off
ebay. There are several sellers in China that sell quality caps for next to nothing. I can pick up 10 for 3-4 dollars (shipping included) while Radio Shack will often run about 5-8.00 for 2-4 depending on the model. Your best bet is to wait the 10 days shipping. The same goes with fuses.
While you may think you only need 2 caps, you will find that most electronics use similar caps.
I do recap a lot of LCD/Plasma TVs, but this problem, while common in pre-2007 TVs, was fixed by a lot of manufactures (Samsung had the biggest problem). I would NEVER buy a TV thinking it could be recapped. Most of the newer sets (last 6 years) had problems with the MosFets, not the caps.
Aside from TVs, I recap a lot of motherboards. Dell is notorious for having bad caps on their boards. When things are slow I'll recap a board, test it, then throw it on ebay with the processor, fan, memory, ect.. attached and they sell well.
