Burned fat shark 5.8 GHZ Tx 100 mw
I accidently burned my Fat Shark 5.8 GHz TX 100 mw while Trying to provide 12 V to my new FPV Camera,
Anyone has Idea where and how to adjust it?

It looks like the first cap of an LC low pass filter blew up. I can't read the numbers on the two what seems to be ST linear regulators. If they are linear regulators, chances are they survived. In case it's a switching regulator, you most likely would have to replace that one too.
If you "just" mixed up pos and neg wires, chances are pretty high you get a way by replacing the capacitor alone.

Hi, I burned My TX by connecting the out put red wire 5v from TX to 12 VCamera and then Connecting 12 V red wire from 3S Battery to my camera and I totally forget to cut the 5 v wire to the camera!! the result is a Smelly White Magic Smoke!...
the Burned /regulator has code ( 470 7m).
Am not Into Electronic Field and Part but i could replace them if you Help me to find these burned parts.
Thanks In advance

You could buy one of those (well, a similar rated one that should do) here:
Note, I asume it's size is 4.3 mm W x 7.3 mm L x 4mm H, if not, you could use those sites to search for a matching one. Unsoldering the blew up one is not that simple for the unexperienced. You thus may try to locate someone with experience doing SMD repairs. The other thing is that replacing this capacitor is not guarnateed to bring your trasmitter back to life, but IMHO chances are at least in tact it would.

Hi, I contacted customers Service from Fat shark, and they asked me to remove the Burned / regulator and I did. My Tx back To life again and it is working Just fine,
Since I am using 12 V camera so no need for that regulator/diode....etc.
Thanks Fat shark- Gregory French
And thanks for Your Help Markus!
