    Another need some help buying replacement caps for my viewsonic lcd.

    Well I dug out this broken viewsonic monitor that would have the power led blink on and off infinitely. So I opened it up and low and behold, about 6 capacitors are bulging.

    Anyways, I need help finding thier replacements.

    All are CapXon branded, which I am assuming are "CrapXon"

    2x 470uf 25v KF105c C650
    1x 470uf 10v KF105c
    2x 1000uf 10v KF105c C652
    4x 470uf 16v KF105c C702
    1x 22uf 50v KF105c C702

    1x 100uf 400V (this one according to some of the research I've done probably does not need to be replaced since it's on AC and not bulging)

    I actually browsed through digikey and came up with some panasonic FC replacements but I am not sure about the ESR ratings and ripples, so I am hoping you guys can point me to the right direction and which specific caps I have to purchase. Thanks!

      fc close and would be fine but i stock fm for a wider range of apps and less parts to stock.
      rubycon zl would be fine too and iirc are availible in the badcaps store.

          Does the ESR and Ripple ratings matter much?

              Yes, see PCBONEZ talk about it here

                  Is that a VE710B? If so, I just recapped one just like that and I can give you the exact list of capacitors you'll need and where to get them.

                      No it's a VX1935wm. I went ahead and purchased some Panasonic FC ones that were the same specs but with the highest ripple rating they had.

                      I assuming this will be fine no?

                          On paper, CapXon KF has better specs than Panasonic FC. Chemicon KZE and Rubycon ZL would have been a better choice (Rubycon ZL is also available from the badcaps.net store here).
                          I'm sure FC would work fine, though.

                                  Yikes, I thought Capxon caps are the crap of the crappiest, so in my mind buying good panasonics would be leagues better.

                                  Should I just go ahead and recap with the FC's since I've already ordered them and they did ship this morning. Cost me $8 and change but I would rather not have to buy replacement ones again since the monitor is not worth much.

                                  Man I hope the FC will be ok, at least for another 2-3 years since this is just a little side project I dug up because the monitor was given to me for free broken a year ago for fixing someone's computer.

                                      Yes, recap with FC.

                                      Before I knew better I recapped two LCDs comlpetely with UCC LXZ, and I didn't hear the customer complain so far, so you should be alright with FC. But if it doesn't work, then order the correct series.

                                          Good to know, thanks I will update once I hopefully get the monitor running.

                                              Hello guys,

                                              I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

                                              I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

                                              Hello,

                                              Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

                                              So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

                                              I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...

                                              Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

                                              First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
                                              When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

                                              I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...
