My Sparkle (SPI) PC power supply has broken. Originally, there was totally no power output. The 5V-standby was not there. I have replaced a few bulged capacitors but not helping.
I was trying to do more troubleshooting but burned more components. Some got burned so badly that the markings were gone. And also, the markings of a few transistors were gone because the component surface was worn out somehow.
If you happened to have disassembled the same PSU model, please help to provide the markings of some of these components.

I am trying to convert a HP EliteBook 840 G7 notebook from a non-touch to a touchscreen. I purchased a complete touch LCD assembly with a screen/back cover/bezel/video cable and swapped it out with the original non-touch LCD assembly.

Hello,
I have a question that's driving me a bit nuts recently.
Is the touch board on Surface Pro 4/5 somehow married to the motherboard? I have a few Surfaces that, after the touch board change, lost all touch functionality.
- I tried flashing the bios (simple ME clean from a known good bios, previous bios didn't have an intergrated hub enabled), reinstalling firmware, reinstalling windows and even new touch boards.
- In one instance, after I tried to troubleshoot by using a known good screen + touch pcb combo on a Surface that lost touch, the touch board... -
Hi everyone,
Following a short circuit on the controller board of my heat pump, I'm looking to replace the components shown in the photos. All I know is that they are diodes (but I'm not sure what type), and I haven't been able to find their equivalents.
The one on the left says: 15A 5BA
The one on the right says: DTZ S47 or DTZ 547
Does anyone know how to identify them?
Thank you very much for your help!
FYI, the card is a siemens RVS21.831 -
