I have problem with my TX no 6528.

Friday I was riding my Rustler and everything was OK. Yesterday I wanted to use it and there were problem - when I turned on car it turned on, but when I turned on my TX nothing happened (LED light was off). I have tried lots to turn on and off etc and still nothing happened. Strange is that bluetooth module is working - I can conenct with my phone and change settings, but I can't change those setting which is needed TX turned on.

What can I do in that situation? Is there any solution to do it in home?

Batteries in TX are OK - Himoto TX works fine.
