Default Futaba 3PM-FS TX & R133F RX Query

[h=2]Futaba 3PM-FS TX & R133F RX Query[/h]
My steering channel(1) suddenly stopped working, I have swapped my throttle and steering servos around on the Receiver and both servos function correctly. I have also tried the steering servos on channel 3 and it seems to respond fine.

Any ideas why my steering channel might have stopped working, thinking I might need to purchase a replacement receiver??

Dual rate/steering rate @ 100%? That thumb switch is easily bumped. Ask me how I know.

If it's not the steering rate being turned down all the way, than I got no other ideas.

Does the steering trim move the servo at all?

The trim does move the wheels slightly, if I set the trim to 100 LFU I'm able to turn the wheels slightly each way. I get a high pitched frequency noise from the front servo when trying to turn the wheels, I'm using Hi-TEC HSC-5998TG servos.

The throttle servos is responsive and almost silent, soon as I use the steering channel I get a high pitched noise and not much movement from the servos arm??
