sjgd 600 fbl system, aileron & elevator servo not moving

[keong]

HI all,,i would like to check what happened to my system, i stopped flying this heli for a year currently on a sjgd600, this morning i trying to re-start everything it doesnt move

1. i turn on the tx and switch on the RX - It dont bind ( i thought must be too long nv fly, lost bind ) - pitch not moving , throttle not moving, all servos dont move

2. i rebind again, got it binded. Pitch , tail, throttle servos moving BUT when i move aileron and elevator, it has no respose.

3. when i tilt my heli all movement...it function as normal

my issue is when i move my transmitter aileron + elvator, it has no response from the heli

What has happened to my system ? perhaps some experienced these before can help to guide me thru it.

thank you so much...
