Hello everybody.

So I have a European version of S5, 900F. When I turn on the phone, everything works but LCD does not come on. I have tested LCD in another phone and LCD works. Touchpanel works normally. I can use MHL adapter and put display to TV and works normally. For some reason the LCD just remains black?? Any help is greatly appreciated

I´m also fairly new to hardware repairing, but I study the field and I´m greatly interested about it
