The signal range on the ch.2 (pitch) of my turnigy 9x was dramatically reduce from about 1000-1800 to 1600-1800. While other channels remain at about 1000-1800. Does anybody know what could possibly cause this?
assuming you can solder well, then just resoler the joints between the pcb and the pot,
just add a little solder to a clean soldering iron, then heat the joint at the place where the leg and the pcb meet, heat it until the solder melts, then add a little more solder to the top of the leg, remove the iron, and dont move until the solder is cold or you could make another dry joint,
good luck , its easy
ok, I resoldered the joint, but now the voltage doesn't change at all, always 4.99V between top and middle joint. Dead pot?
If pressure on the pot fixed it, and not it is completely dead then I would suggest that the legs of the pot were bad,
maybe you overheated it and killed it ,
you should measure the resistance change of the pot between the middle and any outer leg, that shoudl change as you move it, if it doesnt then i would change it,
