    Honda. 31570-VP7-A01

    Hi guys

    Got a Honda. 31570-VP7-A01 mother board here with a K0CA 7A fuse.
    I cant find this fuse.
    Question is what can I replace it with.. I know it AC 7 AMP fuse but what does K0 stand for?

        ok so I replace fuse check for short no short. plug in and boom the fuse blown again. so i checked again finding nothing, no issue no shorts no other blown component and since there is no short I can't inject volt.
        so what me next move?

          show more of the board.
          you probably have a large transistor or driver chip with something shorted on it's output.

                check the ceramic capacitors and large 3pin parts for shorts.
                hopefully it wont be that big driver chip with the heatsink tab under it!
                what is this anyway, a 3phase motor driver?

                  it for the docking station for a lawn morrow.
                  I found the issue, Like I said there nothing wrong with the board no shorts it blow because of incorrect volt.
                  250v was incorrect it meant to be 120 volt.

                    that would do it

                          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...

                          Samsung UN65NU6900FXZA Stand-by light on but voltages on PS indicate TV should be on
                          by DXseekerMO
                          Hello everyone!

                          Tonight I picked up a Samsung UN65NU6900FXZA with a curious issue.

                          Symptoms:

                          1) Plug TV in to AC outlet, stand-by light illuminates briefly and goes out.
                          2) TV does not appear to turn on
                          3) Backlights do not illuminate, voltages associated with backlights on Power Supply are not present
                          4) "Power on" terminal on Power Supply has 3.26v
                          5) "A13V" terminals have 12.9v
                          6) Stand-by test jumper on Power Supply has 12.9V
                          7) Optical audio jack on Main Board illuminates
                          8) With stand-by...

                          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....
