Okay so I accidentally left it on last night.
I heard it beeping in the middle of the night indicating low battery..but I continued sleeping.
I woke up and saw its screen flickering and struggling to stay on.

So I put it to charge.
Now it works ( partially) ...I can access menu etc. Everything seems normal except..
1) the receiver does not respond to it ..( the receiver binds and changes from flickering to constant light) receiver does not respond to any throttle . servos don't work either..

2) usually when I switch it on...it beeps if the throttle is not in zero position... Now even if the throttle is full when turning on...it doesn't beep to warn that throttle is non-zero...it simply turns on...
So have I fried something in it??

Also is there no way to' factory reset' it..??..
... Any help appreciated ...tnx.
P.s its warranty expired last month..so...😂

Wow...looks the the transmitter had already reset all the settings....
I changed the modes to what they were b4......and now its working fine.
