[SOLVED]820-2533 no green/orange light

[aurel476]

Board looks very clean no green light and orange light

PP3V42_G3H present

PPBUS_G3H 0V resistance to gnd 0,5 mohms

check U7000 area 17/18 27/28 fine

real charger 85w good know, tried magsafe board good know

Voltage on DCIN pin of U7000? ACOK present?

 

[aurel476]

DCIN pin of U7000 0.8V, acok 0V

 

[dukefawks]

DCIN pin should be adapter voltage. Check D7005 and check for short on DCIN pin to GND.

 

[aurel476]

pin 2 of U7000 no short on dcin pin to gnd 40mohms and more, D7005 fine

 

[dukefawks]

Voltages on D7005 then? This is coming straight from the adapter to D7005 and to U7000, so there is not much that could be wrong.

exactly pin 2 16.5 and pin 1 0.6V replace D7005 works solved thanks,

with multimeter in diode mode, old D7005 seem work yet.
