    K0305
    K0236
    K0313

    maybe one of you can tell me what it is if there is a equivalent or otherwise where i can get these parts!

            Are they shorted out?

              Intel D865PERL - no Vcore after replacing MOSFETs and MOSFET drivers
              by kotel studios
              Hi,

              Finally got time to fix this board up.
              At first it didn't give any POST codes. Turns out it was an unsupported Celeron D cpu. After dropping in an Celery 2.6gHz the CPU came out of reset with clock signal, but still no post codes. For a while it did work when I applied pressure to the ADP3168 chip, but on next reboot the MOSFETs started to burn. Then I left it as is for months.

              Now I came back prepared. Replaced the bad MOSFETs and the ADPxx18k drivers. Now I don't get any MOSFETs blowing up issues anymore. But sadly, the Vcore is missing. The whole VRM isn't...

              Harman Kardon sub TS11 (ds15 amplifer) blows fuse and mosfets
              by BlackScreen_22
              Hi, I'll start by saying that I'm not an expert and I've reached a point where I don't know what to try/do anymore...
              Starting from the beginning: I opened this subwoofer for the first time with a very strong smell of burnt electrical components, I realize that on the amplifier board there is a hole between V+ OUT and GND about the size of a finger, the damaged components were the shorted mosfets, two damaged zener diodes and two capacitors. I bought everything, I fixed the hole by cutting the pcb and putting a piece of a perforated board.
              I had no problems connecting mosfets and capacitors,...

              Gainward Phantom GTX 980 - mosfets w/ integrated driver NCP5369
              by flerre
              Hi!

              Managed to get a Gainward Phantom GTX 980 in an auction for a bin with components.
              No video out so I started fault finding and found a blown fuse for 3 mosfets. Started checking for shorts and found what I think is a short through all of those 3 mosfets; 0.1 ohms between "VIN" input and "VSWH" output. All mosfets in this gpu are the same ones (NCP5369) with integrated drivers and when I tried measuring the other ones through these ports they were somewhere in the kilo-ohms range.

              So, could I safely assume all of these 3 mosfets are...

              Euphonic Audio iAmp 300 repair
              by NickInBrooklyn
              Hi, i’m trying to repair my Bass amplifier. I shorted cable blew the outputs. I tried and failed a long time ago to replace them and then let it sit for years and now I am working on it again. I think I’ve succeeded this time but I have to replace a circuit protection fuse first before I know . The power supply board in the amp is putting out 76 V and about 16 V. The 16 V seems to be going through a 12 V regulator to power the chips on the amplifier board. The 76 V for the Mosfets is currently blocked by the aforementioned mentioned blown fuse.

              The amplifier board has three ics-...

              Polk Audio RTi100 Plate Amplifier won't power on and intermittently honks and buzzes
              by MrCommunistGen
              My childhood best friend was killed about 9 years ago. His parents are finally letting go of his things, and they offered me his Polk RTi100 tower speakers. The Polk RTi100 towers are one of a handful of designs from the early 2000s that is a full range 3-way tower with a built-in self-powered subwoofer. This is accomplished with a plate amp integrated into the speaker input panel.

              I think they used them for a while, but they've been sitting for at least a few years now. After about 40 hours of driving to their house and back (both they and I have moved in the last 9 years) I got...
