    Connected cap inverted,could that damage the other capacitors?

    I've wrongly connected 3 capacitors with the polarity inverted on my Xbox 360,it was not turning on,and after a few tries one blew up,I touched it and it was pretty hot,the other two were not.I then went and checked the polarity and I've saw that I connected all 3 inverted.Not important now,but the reason I did that was because there was a + near a circle to connect the capacitor,and that made me thought the positive hole was near that +,but that + was for another circle,and I used this to assume that the white portion of the circle was the positive side,but it was the negative.
    So,the main point of the thread,besides obviously damaging the capacitors I connected inverted,could this in any way damage the other capacitors?After removing all 3 capacitors the xbox turn on without them,of course I will not use it like that,but at least I know it did not do any damage to board itself,but about the others capacitors I can't be sure.

    Re: Connected cap inverted,could that damage the other capacitors?

    Maybe but probably not.
    More likely to damage something 'not a capacitor' than other capacitors.

    What happens with polarized caps in backwards is the oxide layer that makes up the dielectric is stripped away. It's the dielectric that makes caps resist DC current flow. When it's gone the cap is to DC current a short circuit instead of an open.

    Easiest way to know if it's broke is to put some caps in right this time and see if it still works.
    Odds are it will be okay but there's no guarantee.

      As I said on the end of the post I tried booting it without this capacitors and it booted fine,but I also hearded that the xbox will boot without a single capacitor and will just have artifacts on the screen,so I still can't be sure some nearby capacitor was damaged by the mistake of connecting these ones in reverse.
      I guess nothing happened with the other capacitors,but I just wanted to make sure,if anyone can confirm that I then can be relieved

        I just did.
        It's not the other caps you need to worry about.

          As PCBONEZ stated, placing a polarized cap in reverse polarity creates a short circuit.

          Check components feeding your capacitor bank.... like rectifiers. A rectifier failed shorted will allow AC to enter the capacitor bank, this effectively creates another reverse polarity situation even for the correctly connected caps.

                Just what I was thinking, I opened up my friend's xbox 360 to put some artic silver 5 on it, and it has all rubycon, nichicon, and fujitsu caps in it.

                  xboxs heat kill their caps.

                    yep.
                    and especially the older xbox360s..
                    because of that dumb red ring of death "fix" where they tell you to wrap the xbox into a towel and let it sit like that for a while (turned on of course!)..

                    this may sometimes "fix" that solder problem for some time, but kills the caps...
                    1 problem "solved"... and another one added -.-

                    god... who came up with that dumb idea?!?

                              do they make towels now?
                              it wouldn't surprise me.. with THAT name, they could easily rule the towel business.

                              (edit: but definitely not with those engineers. aaah, the possible scenarios are endless... chhhhh)
