Whilst pulling a servo out of the receiver I accidentally managed to pull all the other plugs out too!

After spending time tracing all the wires back and refitting I turned the transmitter back on to check the controls.
All controls seem to have gone haywire and I seem to be back to two stick track control for some reason

Any ideas what's gone wrong?
Many thanks
Chris
P.s. Is there an easy how to guide for reprogramming right stick control that I haven't found in the search yet?.I never set the controls up myself
