FlySky FS-i6x

[ege elçin]

Guys, i had a perfectly working flysky fs-i6x until today. When I turned on the controller today, there was a glitching buzzer noise, and the commands that I sent to the plane was extremely delayed, and they were infrequent, i bought new batteries, updated the controller, and opened the inside of it, which looked okey. If you know a solution for this, please help me

Hard to say with that description but I'd start with the cheap stuff. Hook up some other servos to the receiver to see if that helps. Then try another receiver.
