I understand. Those were with cable disconnected. Thank you

Device arrived with minimal liquid damage to mic board. After hardware replacement device has no internal audio but headphones work. Diode mode j6100 pin #32 SPKRAMP_INT_L produces 0.002 pin #33 SPKRAMP_RESET_L produces 0.002. guest account no change checked sound in settings output recognizes...

R6203 climbs to "0.012v" and then back to 0v. 33 ohms.

I have this same board and issue. u6200 and u 6300 have been replaced to rule out and all hda data lines seem ok. Should i start a new thread or continue here?

3215 replaced again. USB port"A" back to 20v USB port "B" shows 5v, 20v then restarts and repeats.

Scroll up--maybe I have been unclear? My goal was to give as much history as possible. Copy/paste from above: I searched forum and read posts. Learned that step one is make both usb c ports the same. Diode mode of LDO rails showed a short on PP3v3_UPC_XA_LDO. Replaced only this CD3215 NOW BOTH...

"Why change a CD3215 that is getting 20v" Because before changing U7000, I had 20v on BOTH ports. Then I changed U7000 and now the usbc ports have changed. Now one is 20v lowA and the other is restarting. This means something happened with ELECTRICAL damage. I can not trust chips that I know...
