After a bad crash. I notice 2 wires and a capacitor loose. I tried soldering all wires. But when I connect the battery it beeps but later it puffed smoked. I notice I have a soldered the reverse polarity of the capacitor. So bought a new one and replaced it. When I connect the battery there is only a beeping sound and no led lights (even underneath). But if you connect the USB to a PC/Laptop that is the time it only works. Do you think the FC is fried and needs to be replaced. Is there a way to check the LED board? Thanks for the help.
