a dude i know, who had a computer shop, closed it, so he told me about giving to me some stuff he had there. Well, lot of crap, lot of broken stuff, but also some useful things. Some things working, some of them quite modern, some of them working but quite older (some Pentium 2 computers... and well, older computer with the typical flexible floopy disks).
So some of those things were DVD players. About... 5 or 6. Indeed one was working, i gave it to my grandma. The rest, doesn't work, some of them can't read DVDs, and others just don't turn on. So i saw 2 of them that can read USBs and SDs and also have DVB-T, so i opened them and i saw, on both of them, the typical exploded capacitor... on the power supply. So i replaced it for another and now it works :D
I made a crazy shit, instead of just welding it to the power supply board, i welded it to a random board i found somewere and then attached 2 cables between it and the old, broken capacitor contacts. Basically, I located the broken capacitor, removed it, and placed a new one of the same specs that the broken one (capacity, voltage and electrolytic).
I know this is a very common issue and very known to be solved, but... well, just for sharing something over here, i saw some people doing the same with more stuff... so I though, let's repair more broken shit I have. I also' got 3 broken LCD screens (with luck, they might have broken capacitors to be replaced :B) and lots of not-working motherboards, some of them also with exploded capacitors.
This is a very common problem that can be easily solved with just basic electronic knowledge... or maybe even without them, just identifying the broken capacitor (or capacitors), identifying the capacity of it (on F) and the voltage (theorically they can be replaced with other capacitors with more voltage), and respect the polarity (since most of these capacitors are electrolytic, and they have a + and - sides, identified on the capacitor with a vertical bar with ------- on it).
