Dear Friends I burned my Turnigy 9x Transmitter by putting its polarity in reverse order black smoke came from it.  I opened and saw a SMD capacitor was burnt.  I tried to replace that capacitor and switched on.  But transmitter is not switching on.  Anybody who can fix my issue please leave their contact number of call me at 9844380830

The voltage regulator will also be burned. Try replacing that too.

Are you sure that was a capacitor?, may be that is a diode for reverse polarity protection.

Edit: Got Schematic and confirmed that was a capacitor.
So now check all 3 voltage regulators.

Thanks Akhil,
May I know how to replace that small spare

At First, If you have multimeter then you should check whether that the regulators giving output

For replacing parts you can use normal 25 or less watts soldering irons or smd station.

If you can parcel that to me then I can fix that to you, or find some one have better experience near by.

I to have a fly sky ct6b and I had also reversed the poles and now it is gone , please help me I don't now little bit about this thing , my number is 9559084030

check out this video.

Hey there thank for the video but I looked around a local repairing shop and he is saying that its ic had gone and the cost for repair will be 700 and time can be around 10days

When I opened it , i didn't saw anything burned but according to AKHIL sir a voltage regulator "CJ78M05" is a faulty one, when I looked at that I saw a minute crack there- anybody with same problem tell me what did you do

Sir can i know the shop where u sanded to get ur transmitter repaired. And did u get ur transmitter repaired

I repaired my TX on my own .... It will be more helpfull if you can send the pics...
