Display won't turn on. Power works

Hello!

I have this apple display which doesn't work. The magsafe works, the USB works, the speakers works, and the computer recognises the screen, in the screen settings. However there is no display in the screen. I've disassembled the display, and no fuses seems broken on either power supply or the logic board. Could someone gie me a hint towards which of the two to replace? Could this maybe be a cable?

最有帮助的答案

Take a flashlight and with the system & display all hooked up and running see if you can see the faint image of your desktop by placing the flashlight on the glass at a sharp angle. If you do your backlight logic needs repair. The LED driver logic chip has a tendency to burnout on these displays.
