Hello everyone,

maybe someone can help me and tell me if:
- it is really necessary to program the IC, or is the "default configuration" sufficient?
- if the default config has to be adapted:
-- where can I get the necessary parameters/firmware?
-- if the default config has to be adapted: can it only be done with PowIRCenter?​

Hello, it seems to be the IR35201. I had to supply up to 0.5A@8V to get it visibly/noticeably warm, but after removing it the short circuit is gone.. I have a tl866II+ for programming, but is the firmware available for download somewhere? Is there anything else to consider when replacing it?

PS: Merry Christmas to you all!

Thanks, the desktop power supply has been ordered and will probably arrive either tomorrow or next week.
What current limit should I set? 0.5A@12V should be enough, right? Does it matter which pin of the inductor I use for the voltage injection? Would it be correct to do it the way I measured the voltage drop? Or should I wire my desktop power supply with connector pins?
Since I don't have a rosin atomizer yet or thermal camera, I will use isopropanol for hotspot detection.​

Sorry for all the stupid questions, but I don't want to make the situation worse. This is the...

Hi and thanks for your reply.

Lisa Sue provided a [URL="https://www.badcaps.net/node/3162775"]boardview file[/URL], and all 12+ pins are interconnected if I see it correctly.
So I tried to measure the voltage drop in diode mode, starting with connector and going step by step to next components.
Between +12V and the first three caps, there is a voltage drop of 0.024V, which appears to be fine for me. But from 12V to the first coil there is a voltage drop of 0V and I'm not sure if this is normal (probably yes, it's just a coiled wire)?

I was testing the board only, without PSU connection, with no GPU/RAM or CPU installed....

Thank you very much, I really appreciate it!

Hello folks,

unfortunately my Gigabyte Z390 Aorus Master died last weekend.
The PSU's short circuit protection triggers when the ATX12V_2x4 connectors are plugged in, all 8x2 pins have a voltage drop of 0V in diode mode and the multimeter beeps on every pin when I probe to ground.
Can anyone help me diagnose this?

Many thanks in advance!

Hi folks,

another newbie is looking for schematics/board view for this motherboard. Would be very grateful if someone had something.

Hi,
my name is Evgenij, I was born in 1983, living in Germany and from time to time I try to repair some electronic devices.
Hope to learn some things here and get some help on my attempts. to repair some electronics.
