Hello.

I once turned off my backlight and now it wont turn on again.
Even after reinstalling the ATK packages.

We may suggest you to reinstall the OS and try again. Please back up your data to an external storage device , then using system restore function to system default. If there is still no work , please take your product to our local service center for comprehensive inspection and help you to fix the problem. Sorry for the trouble.
