We probably need more words than that, and ideally some pics of the tear-down so we can try and see where the damage is. When you say 'no signal' do you mean no control signal, or no VTX, or both ?!

Something has been shorted. Think of seawater as a liquid conductor. Immersion connects every soldered electrical connection in contact with every other electrical conductor. I’d never fly that drone again.
