Hello
We should begin with the controller:
Do you have no picture at all or is there an error message in the bottom right of the screen?
If you have no picture, then please open the top of the controller and check if the power supply unit is still working properly.
If all 4 red LEDs are flashing on the power supply unit, then everything is ok.
If the two LEDS next to the green plug are not flashing, then check the locking device in the black holder.
If the locking device burns though after being replaced, then it’s quite certain that the power supply unit of the controller is dead.
