Trying to cypher you post isn't easy, all it tells us is the bikes electric system isn't working for one reason or another.

The bike uses a TS sensor system so the issue may likely be there with in the TS Bottom bracket/sensor, if they go wrong then replacement unit is needed and a dealer is needed to order a new one.
Though other answers would be useful.

Does the LED display light up at all ?
Does the battery charge ?
Have you got a cheap digital voltage meter to tell us the battery voltage ?
Also how and when did the bike stop working ?
Did you ride it in the rain or leave it out in the rain ?
Has it fallen over, been dropped or had an accident ?
