    finding correct caps

    Hi people. I have another bad PSU this time it seems like some of the caps are bad. It's a LG monitor.

    I'm still learning so I need to ask a this.

    There's 6 caps all near each other 4 are Suscon 16v 680uf 105 and 2 are Panasonic caps I think.

    I'm still not sure if I need to find an exact replacement or not, obviously they have to be the correct v,uf, temp range but do I need to source exact replacements.

    The suscon are
    16v
    105c
    1000uf
    size 10w x 20h

    The Panasonic (if they are)
    16v
    105c
    1000uf
    size 10w x 20h
    these have an (M) and also pet on the side which I beleave stands for polyester?.

    I'm unsure about the 2 with pet on the side, is it super important or not.

    Hope someone can help.

    Re: finding correct caps

    The Panasonic caps are definitely not polyester. Both the Suscon and the Panasonic parts are electrolytic caps. I'm guessing the "M" might be the Matsushita logo. Beyond that, we need to know the series of the parts. For example, "FC" and "FM" are common Panasonic series. Knowing this information is necessary to know certain critical characteristics so as to recommend similar parts. I'm not familiar with Suscon, except I'm pretty sure they are not respected here on BadCaps.

      Re: finding correct caps

      PET =Polyethylene terephthalate the substance the plastic coating is made out of.
      Bit surprised if the panasonic caps are bad - can you do a picture.
      I would replace all with panasonic FR FM and FC in that order best- less good. but you
      need to get the physical size correct.

        Thanks for the reply's, yes PET =Polyethylene yes that's the one. So there's nothing special about these really. I also notice someone mentioning suscon as being rubbish.

        Here's some pictures hopefully they will help, the size of both are Hight 20mm Width 10mm

        The first 2 pics front and back there are 4 of these
        The 3-4 pic front and back there are 2 of these.

          Ok, so they're not Panasonic.

          They're

          * Su'Scon SG :

          * Samwha WB: (page 32, WB is discontinued... Samwha recommends to use MK series instead)

          Replace with capacitors with >= ripple , <= impedance .. basically Panasonic FR, FM, FC like selldoor said would be good.

                mariushm posted much of this, but "translating" ...

                Su'scon: Probably the SG series; made in the 33rd week of 2008; M = +/-20% tolerance

                Samwha: WB is probably the series; M = +/-20% tolerance; W8A is the date/lot code; PET does seem to mean polyester, possibly referring to the sleeve (major brands switched from PVC to polyester sleeves in their RoHS-compliant parts, so PVC may in some way be politically-environmentally incorrect)

                  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:

                  Identifying caps on an old Zoom 9000
                  by Paxman_Swede
                  Hello!

                  I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                  The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                  I have studied the board and...

                  EVGA e-GeForce 7600 GS AGP 256MD2 [256-A8-N542-T2] with bad caps - fixed
                  by momaka
                  I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)

                  So, here is the...

                  Cyberpower 1500AVR UPS repair
                  by quickname
                  I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.

                  Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.

                  I decided to verify that the batteries were...

                  LG 47LB5DF blown power supply board
                  by cmlewis89
                  Hi folks,

                  I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...
