PPBUS is missing
PP3V42_G3H is missing
SMC_BC_ACOK is missing
R7005 near ISL is dead. Should I change R7005 and ISL?

ISL will not work properly with missing R7005. Change the resistor first, verify there are no shorts and then make sure you have proper voltage on pin 2 and 3 of U7000 before replacing, unless of course U7000 is causing a short in which case you should just replace that as well.

Changed R7005 and U7000.
R7021/22/51/52 are fine.

What changed: PP3V42_G3H is present this time. Still no green light, PPBUS or ACOK.
ISL also gets pretty hot.
