    looking for a source for a Diode for P65VT60 SC card

    Hello,
    I am attempting to repair the SC card in a P65VT60.
    I have found the transistors on ebay, but there is an elusive diode on the board that is shorted out that I can't find without waiting 5 weeks for a CHina delivery.
    The diode is:
    RFUH20T3S diode D401 on the board.
    I believe it is
    D16401
    panasonic part # B0FBCN000012

    even though I have looked extensively, I am open to suggestions.
    It's used in a handful of other panasonics.
    thanks,
    dave in NJ

    Have you tested it out of circuit ? The 2 forward legs are tied together and will read as a short.

      thanks for the suggestion, on the 6 transistors and this diode, there was a short on all three combos of legs.
      1 to 2, 2 to 3 and 3 to 1, all shorts

          thanks, yes, I can buy it from ROHM but the shipping takes 5 weeks!

            While on the board, the diode will test as a short. That's because the igbt's are shorted. Remove them first and your diode should be fine.

                Marian Trace Alpha sound card repair help
                by Christos Tsiligiannis
                Hello to the forum.

                My name is Christos, I am new to the forum here and i am posting from Greece.

                So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

                To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

                So i tried asking for a schematic from the company and they would not give me one. Instead they...

                Graphics Card mounting frame
                by Kemer
                Hello, I removed the graphics card from my laptop and I want to heat it in the oven. What I want to ask is, is it okay to heat the card without removing the metal mounting frame on it?

                As you can see in the photo, there is a plastic (black) gasket between the metal frame and the card. It sticks the frame tightly to the card.

                I previously removed the metal frame while heating it, but it is quite difficult to separate it from the surface it is attached to. If there is no problem, I do not want to remove it.

                What worries me right now is the possibility that...

                EVGA Nu Audio Sound Card - Not Working
                by FZG
                I have an EVGA Nu Audio sound card that is not working properly and I need some help diagnosing the fault (preferably by someone who owns this card and is willing to take some measurements).

                The card sort of powers up (LED lights are coming on and the relais is clicking, some voltages are present) but it is not detected in Windows. I tried installing in two different PCs and tried several driver versions but the card was never detected anyway. So I thought this is probably not a driver / software-issue and then disassembled the card to take some measurements.

                I found...

                Gigabyte Aorus 1080ti - card not initialising
                by benwaterson
                Hi there.

                Have searched various forums but haven't come across the exact issue I am having.

                Bought the 1080ti with a fault (randomly shutting down, black screen , fans full speed etc). Previous owner had replaced thermal pads but many were too thick on inspection.

                I tested the card in windows, all loaded up ok. Put some load on the card and it crashed. GPU was reporting 92 degrees C at the time.

                Switched the stock cooler out for an AIO water cooler from my 1080 FE, booted the card back up - temps were much better and allowed some load to be applied...
