TESTED with another LCD and backlight works ok. cable is ok as well! So problem must be from old LCD!

Any solution anyone?

LCD Backlight

I've solved many phones with similar problem. Just look 2 contacts behind the LCD for the loght. 1) Resolder that 2) An Inductor near it can be fault. resolder it.
