    Replacing Monitor Caps

    Recently, my ViewSonic VX2255wmb-3EU monitor started refusing to start up, the power light coming on briefly before shutting down again, after searching the internet a bit, I decided that it was probably a caps fault, so, I opened it up and what do you know, one of the caps was bulging out. I'm very new to this and so was wondering if you guys and your many experiences might help me in getting decent replacement caps, the current ones are:
    Capxon 10V 2200μF 105°C KF P737 VENT (Bulging one)
    Capxon 25V 1000μF 105°C KF P738 VENT
    Capxon 10V 1000μF 105°C KF P729 VENT
    Capxon 25V 220μF 105°C KF P736 VENT
    I've noticed Capxon have a reputation of this forum of being either bad or 'ok' so, I won't be replacing them with the same ones which is where you guys come in as there is SO many components to chose from, my simple mind gets hopelessly confused. (P.S:: Do I actually need to replace all of them as I want to risk breaking the monitor as little as possible)

    Thanks guys!

    Re: Replacing Monitor Caps

    I'd use the following. Replace all of the caps. They can fail without bulging, and even if the others haven't failed yet, they won't be far off.

    For the 2200uF 10V, http://uk.rs-online.com/web/p/alumin...itors/3150366/
    For the 1000uF 25V, http://uk.rs-online.com/web/p/alumin...itors/0571404/
    For the 1000uF 10V, http://uk.rs-online.com/web/p/alumin...itors/3150344/
    for the 220uF 25V, http://uk.rs-online.com/web/p/alumin...itors/3150552/
    I love putting bad caps and flat batteries in fire and watching them explode!!

    No wonder it doesn't work! You installed the jumper wires backwards

          Dear Sir/Madam,
          I have experience of caps replacement.
          Remember that it is good to replace all caps.
          Many bad caps have no any visible sign.
          Bigger V. and uf. have no problem.
          I only replace caps with those of Rubycon and they are wonderful!

            Attention To Friends Doing Monitor Caps Replacement:
            Replace all caps including those inside the power brick.
            Replacing the sm. caps has the risk to tear off the circuit when removing them.
            Replacement of the electrolytic caps has no any risk at all.
            Very old monitor may have dead spots soon and is unwise to do replacement.
