Does the VTX have a flashing led when powered like the FC? i have connected a battery a couple times without the antenna on and hope i have’nt fried the VTX

Thanks

What VTX are you using and what FC? Usually they have an LED to show if the VTX has power, and another LED/Display to let you know that channel it is on

Yea it’s burnt out I’ve had a good look the leds only light up when powered up then go out, they then flicker when you press a certain spot, I’ve ordered a new one lol
