controller board powers off when backlight disconnected

I'm using a RTD2660 lvds lcd controller with a B101UAN02 LCD. the LCD works fine but after removing the led backlight from the panel the controller board will power up the lcd for a second or not at all. if i reconnect the backlight it all works again.

I believe i might be activating some sort of safety mechanism built into the firmware so i'm looking for either a firmware, help modifying the firmware or a hardware workaround to trick the controller into believing it is powering the backlight. I am not sure if it is the controller or the lcd board that is automatically powering off.

has anyone else encountered this problem before?
