I have an 820-00923-A that is showing the battery charging icon in a loop. All 4 ports are pulling 19.7 volts. I've replaced the battery with a new one and still the same result. Tried SMC reset multiple times. The same thing will also happen with or without the battery plugged in (including without the battery sense flex plugged in as well), except it will loop once then turn off, until you press the power button then it will do one battery icon charging loop then turn off again. No signs of liquid damage. Did a quick check on diode mode readings on some of the LDOs on the CD3215s and all diode mode readings seemed similar, around .470ish. Checked SCL and SDA lines on battery sense flex connector and they both showed 3.4 volts in a looping fashion in accordance with the battery charging icon showing on the screen.
Any help would be appreciated on this.
