I have a DX3R Pro that I bought from Amain that would not turn on after being used for about 2 months. Emailed them and they told me to contact the service dealer which is all fine, No issue with that.the problem that I have is by the time I send the controller back and pay to send it over and back to the USA it almost defeats the purpose in geatting it repaired.My fault for trying to save a few dollars. A mate tested the controller and found the on/off switch is faulty. can this be bought through a service agent.

Find someone there that is used to working on electronics. Many switches can be carefully taken apart and cleaned. If it was mine and the switch itself was beyond any kind of repair, I would be looking to an electronics store for a suitable replacement. Not worth all that time and money to send back to the US from Austrailia.

spray a little bit of wd40 in side the switch mine did the same thing
