Hello. I am wondering is there any chance to change LED display which shows battery state and speed of moving? When e-bike is turned on, diodes are not turned on. E bike not working. Where i can find new one? Can i change it for non original LED display?

modelName: CTB 28" Da, E-Bike, Nexus-7G, 36V/10Ah
model: KLE012-01 (or its 013, I'm not sure)

Thank you in advance,
Branko Stancevic
