Q2300 is not shorted, it passes current from vbatt to vcc_main and when there is a short on vcc_main, it heats up due to current overload.
what you need to do is bypass Q2300 by jumping from C2333 to C2303.
This will then allow a lot of current to bypass Q2300 and all that power will heat up the real short on VCC_main and make it easier to find.

Any heat on U2000? (PMIC)

gulzaib07 · 02-18-2018, 18:02

no there is no heat on power ic

P.g_sparkles100 · 03-24-2019, 10:01

I realized after the jumping of c2300 and c2303, the pmic becomes hot. I think it's wasted and has to be changed or it's just a diversion?
