Hi master, this resistor R7005 keeps blowing up. What could be the issue?

Missing Greenlight on the charger. The customer said its been water damaged. I cleaned up some corrosion but first need to fix the green light.

I manage to fix the short... Post details here. Only missing green light now on the charger

I removed C7090 and without the cap it shows now = 0.430
replaced with another cap on C7090, and not it shows = 0.399 and now I have a green light on the charger with my DC Supply but not normal charger.

PPBUS_G3H is now 8.1v only

you must work on isl6259 . ex : is there an adapter voltage behind the q7130?

I changed the SMC and now I have Greenlight/orangelight on the charger with 8.5v... It was not the ISL6259... Usually, 8.1v on PPBUS_G3H is an SMC failure from experience. So will check all other voltages now. and post them here...
