I have a x-sus board that has 2 shorted IGBT transistors 30G124. I also want to replace the driver IC and this part has the marking FXB20-73711. Any idea where I can find this part?

by osrexHello, this is my first post and im just a beginner, so be easy on me guy. thanks
i have a LED chandeilier that switches colors from white to cool white to warm when toggling the switch, it has 24 LED arms, each arm is 30 CM length.
i have no datasheet at all for the LED lights, all i have is its length.
long story short, testing the chandelier on the ground, and it works fine for 1 - 2 - 6 hours, no problem.
as soon as i fix the chandelier to the ceiling and bury the driver inside the hub,... -

by charifNeed Audio Driver for Thomson P14C4BK128 (Windows 10/11)
Hi everyone,
I'm looking for help finding the correct audio driver for my Thomson P14C4BK128 laptop.
The sound is not working properly, and I believe the audio driver is missing or not installed correctly.
Here are the details:- Model: Thomson P14C4BK128
- Operating System: Windows 10 64-bit
If anyone has a working link to the driver or knows where I can download it, I'd really appreciate it.
Thanks in advance for your help!-

by bohabohaHello all am trying to reinstall my AMCAP Microscope on windows 10 but it is not working anymore. But the cam and the drivers are present in the Device Manager but there it saysWindows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) the drivers is : gl usb2.0 uvc camera device driver and i also get this mesage: Windows found driver software for your device but encouβntered an error.
but it is quite strange because it did work on this same OS for one week ago and even for sometimes ago on that same but now nix.
any help?-

I have two power amplifiers, both having their IGBT blown on the PSU.
The original mounted IGBT where marked with IRGB20B60PD1PbF and the gate driver is a IR2156STRPBF.
I looked at mouser and digikey and could not find any available IRGB20B60PD1PbF and somehow ended up using a Bourns BIDW20N60T.
I replaced the gate driver, the gate resistor and both IGBT. But as soon power is turned on, both IGBT shorts out completely (gate, emitter, collector) and the fuse on the AC line gets killed.
So I though i missed a capacitor or diode. I removed... - Loading...
