First time working on a switch and I just have some questions about my fix. I’ve been looking at the Board diagram and it looks like I’m reading shorts by both 3 phase buck regulators. I also have shorts by the USB Type-C Power Delivery chip which I believe will go away after I replace the Video chip? Also a few by the DC0 511 chip. I’m just wondering if this will be fixed if I replace the video chip and maybe another chip? Or is this a lost cause?
My best guess from what you have described is a shorted P13USB I would remove that IC then re-check shorts. I know it connects to the M9T236 power IC.
