    I would remove those two power MOSFETs from the PFC section and test them, if the relay comes on ,it will blow the main fuse again.
    So you do not have 160Vdc Voltage at C1201?
    Did you download the service manual?

    well the board came in, and i replaced it and everything is fine now...they havent picked it up yet but i imagine they will let me keep the dead board...idk how ill finish fixing and testing it though, since it seems the psu was split across the 2 boards...

      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)...

      Replacing resistor fuse in Sony DV charger
      by corrize
      Hello, I have 2 old chargers for Sony DV, and I found the same resistor fuse dead. Fuse is a crossing component : 0,47 Ohms (0,125W deduced because the lenght is 3mm). But I can’t find the same for buy.
      So, I want to replace by another like 0 Ohms, 1 Ohms 0,125W,

      It is the same please ? I guess it’s the same, the only change should be the time to burn ? Thanks...

      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 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...

      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....
