Hi! A few weeks ago i came back to home and found that switch was not turning on. Tried to connect into dock, directly into charger, hard & soft reset but nothing worked.
Now after inspecting with a DMM in diode mode i’ve stumbled upon lots of what seems to be shorted caps. I know some of tiniest form factor caps can have very low resistance to ground, but there’s a lot of them, in addition to a bigger ones. They’re placed just under Tegra and DRAM.
I’ve also checked the rest of chips that common fails (Pi3USB, M92T36…), no shorts at all and voltages were OK.
USB C draws about 0.46 amps.
In addition, some voltages were measured through test pads.
