today i recieved the tx from quadcopters
in menu> function settings> display when ever i move the throttle and rudder stick no movement in the bargraph
ail and ele are good
is this the problem of transmitter or anything
please help me i'm a newbie to this hobby and this is my first transmitter

Problems may be
1) Bad firmware.
2) Bad Pot inside.
3) detached wire connection between pot and board.
did you check using Rx connecting to servo?

Well as praveen said there can be any of the above 3 problems
I think you should contact your seller ASAP and don't try to repair it on your own

Try flashing the radio with ER9x firmware or ship it back to quadcopters.Flashing the firmware might solve the issue but it may void the warranty .

 @prveen,harsh17 for your input
no i dont,actually i dint have any servos with me rightnow
