I lost the 3.3v

I have more than 3.3V on my OLED switch board. Does anyone have any ideas where this is coming from?

Thanks in advance.
Here's a link to a picture of the motherboard.

How much more and how are you measuring it?

when I measure with a multimeter it indicates 0v

Hi
no one has any ideas

The max IC next to the 3.3v caps is the source for the 3.3 line. If it is missing that IC is probably damaged (assuming the other lines are ok and present)

Measuring your board in diode mode and comparing to the boardview can also help narrow down the issue (when measuring in diode mode the red lead is on ground, black lead on the point your measuring)
