Capacitor value in 2ds motherboard

Hello,

I received a 2ds for repair with the syntoms that it wont turn on. Ive tested the screen and it appears to be good. Furter inspection i noticed that there is a component missing in the motherboard, has seen in the figure below:

It is labeled has C91 and it seems similar with other capacitors near the area but i don't have a way to measure it.

Does anyone have a schematic or knows the value of this capacitor?

Regards

Miguel
