Hi,
Please tell which battery you are using. Also, on switching your Tx on is it displaying "switch error" ?

hi utkarshg13
  iam using duracell AA batteries ....no display and no sound when i turned on...

what will be the problem......?

You might have a bad connection in the transmitter or it may be defective.

Are they new and did you check the voltage? Does it has any port for adapter to plug?

@ramarao it seems there is some faulty/broken connection of power supply in your Tx. Might be the supply wire connection is broken inside.
When did you ordered this and from where?

Agree with Kiran. Are the batteries new. Try to check the voltage with a multimeter. Flysky FS TH9X does not works below 9V(although sometimes it shows false readings.)

Also, do not switch ON the Tx without antenna module mounted.

Also check the cell holder.sometimes the connection might be broken.

@kiran rc and utkarshg13

iam also same thinking there is problem in tx power supply.

batteries fully charged and working fine in my transmitter

same batteries i placed  in this new transmitter

my friend ordered from Quadkopters.com he recieved on thursday..

i send message to satyagupta sir .. waiting for his rply...

Just do one thing more, the 8 cell holder in the battery compartment. Pull it out place all batteries in it and then check with a multimeter.

my suggestion do not do anything, wait for satyas  revert..... you may get a replacement too much of feddling can void replacement warranty.

I hope steps suggested has solved the problem

Problem solved ... Thank you Satyagupta for your help . Today I' ve learn some new things about troubleshooting these kind of problems...

what was the issue......
Curious to know!!!!

So the cable that goes from the back cover case to the main board was un plugged. We test couple of TX by opening and checking the pots hence guys might have forgotten to plug the cable back.

Yes cable unplugged
