Have a 820-2915 with soda damage. Replaced everything affected by the spill but still no fan spin.

Checked power rails and pp5v_sus is pulsing up to 0.135V then 0v. Replaced Q7840 and D2400 but same results. Checked and have no shorts. Drawing steady 0.15amps on power supply

What to try next?

Does it work now?
It requires to connect bench power supply through 85W cable, when no charger available...

Yes but pink lines through screen... should be fixed after GPU replacement.

cable on bench power supply is suppose to be 85 watt but board only draws 0.15 amps on it. Power up no problem on standard apple 85 watt ac adapter
