    Bad caps in two digital photoframes

    Hi all,
    I have gone round and round with two companies trying to get parts for two digital photoframes with bad caps. It appears both units have the same caps, yet since they oozed out, I can't find any identification on them. I have uploaded a pic in hopes someone may be able to tell me what they are.
    Cheers and thanks,
    Kim

      those are crystals, the brown shit is glue!

          stj,
          Pretty quick response, thanks. Any idea why these are in a photoframe? I can't find a schematic and they both will not power on, with solid power supplies. If that is glue, then it oozed out all over the placed in the other unit.

              Those are crystals thatare required by the microprocessor ic, they are glued in place so when people drop and bang the frame around the crystals that have fine wire leads don't break off the board.
              Whats the model number?

                  one crystal is probably 32.768KHz for the date/time tracking, the other is probably 24MHz for the cpu
                  and they are probably fine, you just need to scrape all the glue off the board.

                  possible schem.

                      The glue that's on your board is well known here to go conductive over time and mess up circuits. I suggest removing as much of it as possible and then cleaning the board with IPA. If that doesn't bring back the board, then we will go in further and try to see what is wrong. But with the brown glue in there, there's no telling if that's the problem or not (in many power supplies, it is, hence the suggestion to remove it.)

                          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:

                          Heathkit IO-4205 Power Supply Caps
                          by eryjus
                          Hello,

                          First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                          I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                          I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                          ...

                          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...

                          Help with switching power supply caps
                          by captain150
                          I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                          I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

                          Gigabyte GA-6OXT :: caps question
                          by Foetuss
                          Good evening

                          I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                          Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                          But I was also suprised about the bigger boys, which are 330µF 25V.
                          Could it be they used 25V caps because they were cheaper / available at that time?...
