    What do these capacitors do.. ?

    Hello
    Please can someone shed some light to what these 3 capacitors actually do.
    C5502, C5503 and C5504.
    I am waiting for new ones to be delivered plus the fuse.
    I am expecting the fuse to arrive first so would like to know if I can try the laptop after ive replaced the fuses without the capacitors.
    Or even does the laptop need these capacitors to work ?
    See attached

    Cheers

      Filter caps.
      Are they tested bad or what?

          yes motherboard had a short to ground, apparently all three capacitors and fuse needed replacing, repairer couldn't return them as he lost them?? , I have ordered new.

          What would happen if I turn on without capacitors soldered onto board?

          Cheers

              A funny fuse story – Lumix LX100 II
              by corrize
              Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
              I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
              The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
              There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
              And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

              After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
              by dragon3x
              Hi, I have some 32 bits computer motherboards that need repair, as they fail to
              power on.

              Here are some examples :

              (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
              switching supply area).
              (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
              than 6.3 V.)

              1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
              I replaced capacitors with aluminum-polymer.
              3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...

              Samsung UE46ES8000 Blown fuse but no other signs of short
              by jesterace
              Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...

              Help replacing fuse on my Mimaki CJV300-160 vinyl printer
              by jshhh
              Hi guys,

              I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.

              How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.

              Anybody know how to remove this type of fuse?

              (The fuse is toward the bottom of the image labeled F2)...

              Argon SA1 audio amplifier power-supply - fuse blown after fixing the short?
              by Babbar
              I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.

              Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....
