820-00138 No Audio

[Revive]

No PRAM chime, no output device detected, no corrosion. Theres a dent around the audio jack but thats probably a symptom of a frustrated consumer unlikely the cause.
I don't have the BoardView for 820-00138 but 820-3662 is close so thats what I'm going by.

R6200: 3.3V
L6200: 5V

Any idea where to go from here?

Voltage on C6212 and C6217? How big is this dent?

 

[Revive]

No Title

C6212 P1: 3.3V, P2: 0V
C6217 P1: 4.5V, P2: 0V

Dent is pretty small

There should of course be voltage on those 2 caps. Should not be hard to figure this one out.
