Okay I got the idea but while Im trying to understand this idea :) Im a bit confused about the easiest way to find for example that filter capacitor. Because I cant see anything on thermal camera so which is the easiest way to find it my friend?

I put one side to L7210 1st pad which is CPUCORE_SW1 and other side of my multimeter to F7000 second pad which belongs to PPBUS_G3H line and read on the same mode of my multimeter (resistance Ohm mode) and got 0.003 ohm and on buzzer mode of multimeter I get signal when I put the multimeter...

I got this one if I did it right my friend.

I got 002,4 on both sides of F7000 on ohm scale if I got you right. Im going to add the video of it. https://www.veed.io/view/25757746-5638-4353-9ec5-8c13c7dc6e6f?sharingWidget=true And I got 002.3 ohm on L7210 which is on CPUCORE_SW1 line. I read it with the same method on the video

PPBUS_G3H around 0,017V on RB641 3V3_G3H_RTC around 0.034V on CB400
