powers on work but the screen is black

Hallo,

black screen of my Samsung Galaxy Note 3 SM-N900.

I can enter recovery mode and download mode and the screen is work normally, and when charging, the screen display green battery charging, so the screen is not broken and well connected.

but when turning on my note 3, the screen remain black even I hear start up sounds and touch sound and see the LED lights.

I did booting, wipe data factory reset and wipe cache and flashing.. but still note work!!

what is the reason that the screen work in download and recovery mode.. and not work when I power on the device!

any suggestions?

thanks in advance
