Yuneec Typhoon G Q500 4k does not work

[Dusiek]

Hi!
I have a problem to turn on and bind my Q500 4k drone. I got my drone from friend of mine , It was in not working condition. I opened the shell to check all connections. Everything seems ok. When I turn my drone on the light on main board starts to blink red/blue, but after while turns to steady red. The receiver led is blinking orange all the time. No other lights or sound from the drone. Thank all for any help or suggestions.

What color is the rear main LED (Below the battery door) blinking?

None leds are on except the one on main board and receiver.

Sounds like the main flight board is fried. Does your Q500 use a standard Q500 battery or has it been converted to an aftermarket battery?

I use standard battery. I also think that the main board is bad. Thanks for your help.
