I tried everything and it is still not working.. does it mean that it is an hardware problem? is there something else that I can do?



Sure sounds like a hardware issue then. Can you verify the power gets to the LED controller board?

I have the same problem (also coffee spill), and there was more damaged than the backlit. It was completely dead. Meanwhile I changed an IC on the logic board, so now everything seems to run except the backlit and the battery-charging.

I tried the software resets from Richdave, and pluged in another display. No change.

So where can i start now to fix the issue?
