I was asked by a friend to fix their switch.It won’t power on and I see no signs of life. After watching a few NorthridgeFix videos I’ve done some diagnosing.

The capacitors in red around the max77812 are shorted.

There is also a capacitor in blue around the BQ chip that has a voltage drop of 1 volt.

I believe my next step should be replacing the MAX77812 chip but I wanted to see if anyone had any other suggestions first.

I would take the two red marked caps out and check on which side the short is. SoC or Max ic.

Likely not actually shorted.

I’d search the forum instead of watching videos :slight_smile:

That all being said. It does look like someone has been to rough with their probes
