Good evening.
I have this joystick on the bench with the following situation:
It works normally on cable, however, when connecting by battery, the led just flashes without synchronization, and when pressing the synchronize button, nothing happens (no lights).
I did the basic tests:
*no short on the primary regulators.
* I replaced the Q9.
*nothing heats up.
*sync button works fine on test.
Any tips?
