Missing cap on RF board ?

[polo]

Hi,
I've bought an X9D plus SE "as is"in a non fonctionnal state and a few missing part,
mostly because a got a non SE and wanted to try the hall gimbal.

RF board seems dead, no apparent cause, until I realise that a couple of capacitor seems missing :

when I try to use it, the speaker make a little "pop" when I plug the battery, then nothing.

first, what do you think ?
second, I would like to try to solder some capacitor to see if it bring it back, but I have absolutely no idea of the value ?
in a last resort, I still have a roll of 1210 10µF I could try
