are you saying that the power supply will not output any voltage unless the led power cable is connected ?
Yes most models will not output any power if not connected, now there is a way to manipulate the Main board into thinking the strips is connected. But from my past history i have always found that if the main board and power supply are coming on and you have an image with no back light then 95% of the time you have a faulty LED strip or LEd.
