    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

          Re: Replacing Monitor Caps

          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.

                  HannStar Hanns-G HC194d LCD monitor repair
                  by momaka
                  Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                  Replacement caps for Samson Resolv studio monitor 65A Amp board.
                  by black6host
                  Good day!

                  I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.

                  I'm going to replace the caps and I'll be the first...

                  Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                  by momaka
                  I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                  For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                  https://www.badcaps.net/filedata/fetch?id=3591772

                  It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                  Wise Wing F199 19'' LCD monitor - recapped
                  by momaka
                  Looking through my repair pictures and notes, it's been a long time since I posted anything in the LCD monitors section. So here goes that.

                  I'm dedicating this thread to one of the very first LCD monitors I repaired (if not the first one), which was more than 10 years ago now. The monitor is a Wise Wing, model F199. It's a 19” CFL-backlit LCD. I got it for free off of Craigslist in 2009 from a guy, who said he bought it for cheap from Wallmart and the monitor worked only for a little less than 2 years before quitting.

                  When I saw the Craigslist post, I wasn't...

                  Westinghouse L2210NW LCD monitor - bad caps repair
                  by momaka
                  Here's another LCD monitor repair: Westinghouse L2210NW.
                  Quick specs: 22” CCFL backlit LCD, 1680x1050 max resolution (16:10 aspect ratio)

                  I got it with a bunch of desktops PCs from a repair shop that was trying to free up space a few years ago. It seemed like a cheap monitor, so I didn't really care that much at first when I picked it up (and indeed it is, picture-wise.) But hey, free is free, so I can't complain. Moreover, it looked clean and the screen didn't have any significant scratches or blemishes.

                  Pictures of the monitor outside/case after a brief...
