Switch SD Card doesn't get recognised

Hey folks,

My V1 switch doesn’t detect SD cards.

Sometimes I get error Code 2016-0641, sometimes the switch just turns to Black screen when inserting the sd.

I checked the voltages as on the image

I sometimes have 3,3 volts (I think it’s missing when switch goes into sleep Mode?) . 1,8 volts is missing completelly.

Is there any fix?

I already replaced the 3 leg component, should I replace the other or the MAX IC as well?
