No power up, 15V 0.18A power draw, shorts near M92, MAX77620 and BQ - Fixed

I had an issue yesterday where a switch v2 wouldn’t turn on. It was drawing 0.18A at at 15V and I found a short below the M92, shorts around the MAX77620 and the BQ chip, as well as an open line below the P13 chip. Removing the LCD FPC cleared all of these.

The problem ended up being a short in the LCD FPC connector so I decided to make this post to help anyone in the future.



Update. The open circuit near the PI3 was caused by an unrelated issue. It connects to pad under the soc that was not making contact with the soc. Reflow fixed that.
