Flysky GR3E channel 1 not working??

[fstnd]

Hello, anyone ever had this problem? With "not working", I mean there is completely no signal. But only on channel 1. Channel 2,3, rest works

I drew a circle around channel 1 plug

No sir can't say that I have. Had that happen with any reciver. Has it gotten wet by chance? Is it new or older? Did you try a different servo to make sure it's the reciver?

It came like this from factory...
I tried 3 servo's. All of them worked on channel 2 but not 1
