Good afternoon,
I have the same problem. Not yet probe with the change of that coil.
A query, how much is the value of the coil? And in case the coil is not the problem, what is the IC of the backlight?
Thanks for your help, and sorry for my very bad english

Sorry but I do not have the phone with me anymore, so I am not able to tell you the value of the coil. I just took it from a dead phone and it worked just fine ...

Thanks also
Now I have another problem. The cellphone only charges usb mode and never ac mode. It is not the charger or the cable, nor the USB connector, nor the battery. The problem is somewhere on the motherboard
