820-3332 Intermittent power/green light

My bad ACIN: zero volts
ACOK also missing but 3v42 is 3.42 volts

 

[JohnB8812]

R7010 and R7011 are definitely blown both measure way below what they should.

Resistors don't blow and get lower in resistance. Measure some voltages around there, also DCIN on U7000

 

[JohnB8812]

DCIN: on U7000 is 18 volts. DCIN on Pin 1 of R7010 is 18 volts AC in is zero anywhere I measure

 

[JohnB8812]

Pins 10-12 measure 3.42 volts

 

[JohnB8812]

SMC_RESET_L also 3.3

 

[JohnB8812]

Ok so R7010 measures normal I went back and remeasured to make sure. R7011 only measures 2.9 ohms which is not correct. Continuity from R7011 to ISL.

 

[JohnB8812]

Replaced ISL and that resistor and it looks to be good to go. I'll call this good for now
