I accidentally dropped my Kanger Tech Cupti a few weeks ago, however it was working for a few hours after the fall, however when I tried to use it the next day it has been switching between a number of different faults. Sometimes it will say 'tm' when I put the battery back in, sometimes the screen will keep switching from facing me to facing away, and other times the wattage will just run down to 7W and then just turn off.
I have tried changing the battery and the CLOCC but it's still not working. Is there a way of resetting?
I would appreciate any advice as i'm struggling without it! Thank you in advance
