DDJ ERGO

Hey guys, might be posting in wrong subforum, but:

I have been dumb enough to spill pineapple juice on my DDJ Ergo, and now the main fader as well as the right volume controller do not function anymore. Do you guys have any suggestions on how or if it is possible to solve this? Or do I just need to go to a shop and have it repaired. Any input is welcome. Cheers!
