Check the switch, it may be worn.
Open the TX and check connections with a multimeter.


EDIT: Try to stop moving the switch when the led lights up, not complete to end
position. If the TX is starting ......

At first glance, it looks like a power supply problem to me. Double check your battery first, and make sure it's not tanking under load.

finally, after 2 evenings are managed to fix it. of course was not a simple switch defective or low battery :whistle: . I had to replace the voltage regulator that power of the processor and one mosfet . not finding what exact I have put one a little bigger. so this time you do not break so easily. ;)
