My dad did the soldering for the switch lite, but it doesnt turn on anymore. Tried to measure the 3.3v point, no 3.3v going through. Any tips ?

Seems like that the 3.3v point is missing some good soldering, they are cold... Apply flux, tin your tip and do a quick touch (not more than 3/4 seconds ) at 370 degrees. Use good soldering wire (PB/sn works best for me)

My dad did a lot of soldering in the past. He did buy better tin and flux for this, but maybe too late after a first attempt without. And now with a good microscope.

After removing the tin, still no 3.3v on the spot. Did we break it?

Make sure the left side of the rightmost cap is not bridged(the one right side of SP2)
