Next thing we do is to solder a new C6990. Once done, run diode mode measurement of D6905 Pin 3 again. The measured value is normal.
Plug in AC adapter and measure the voltage of D6905 Pin 3, L6995 and L7030. All going well.
Measure the voltage of U3100 main power supply Pin H11 VBUS and logic board power supply group by group. All going well.
