    Gateway FPD1830 Inverter

    Seems like there's a few variations of the FPD1830. This one shows a green power LED but nothing else. Power supply caps all look good and tested okay for ESR.

    The inverter is an Ambit K11I010.00. It had four 100 uF, 25V caps with questionable ESR, so they were replaced (Panasonic FM). It also has a blown SMD fuse, 3.5mm x 1.5mm, marked "FT". The MOSFETs all have pins 1-3 and 5-8 shorted together by the PC board. Just running them in parallel pairs for capacity?

    What does the "FT" fuse code decipher to? There are conflicting versions on the web, but obviously it's not a 500mA. Doubtful it would be slow blow, either. Littelfuse has a "T" code for 5A.
    Maybe this would be a suitable replacement?

      Re: Gateway FPD1830 Inverter

      To confirm: a pdf that I found on surface mount fuses shows FT is a 24 volt 5 amp fuse. I'd buy a few to have on hand. Whatever blew this fuse will blow it again.

      By the way, due to the far away pic, I can only assume that F1 (the FT fuse) is on the input of this board. I'd do a resistance check from each side of the fuse to that board's ground. There may be a direct short.

              Yep. Those 4 Sanyo caps were a major problem with that model inverter. Because of their compact size , they dried out, shorted and probably in your case caused the fuse to blow. I believe the "F" in FT stands for Fast blow. The 1206 case style should work fine.

                  These are 24VDC, 5A, 1206 package.

                      Just repaired the same model Gateway monitor by replacing the four Sanyo 100uf 25v caps on the inverter with two 220uf 25v Rubycon's and the fuse labeled "F1" that is right next to one of the caps.

                      Symptoms were; Power would stay on and blank screen.

                          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...

                          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....

                          Vizio E55-E1 bad backlights or bad inverter?
                          by x_orange90_x
                          I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.

                          I don't know how exactly to test the inverter itself. Is it...
