Iphone 5c no display


I have one iphone 5c with no display, no backlight. It's not a water damage. Customer give to me with no display for change screen. I change but same problem (lcd is ok on another 5c), i test many screen. I restore many times but same. In recovery mode, i see the logo. When i restore, no display on iphone 5c, restore and activation is ok. I restore on two pc (only motherboard, battery, and connector) but same. I wait one week with motherboard only and restore done, same problem.


I think it's hardware problem, have you got solution please or schematic.

Thanks in advance.

I have the exact same problem although I have the schematics for the 5 5s and 5c ive tested the backlight filters all three show continuity..i tested the backlight diode also called the backlight ic ( wrong lable its a diode ) only thing I haven't tried is the coil which they don't usually go bad ...when they do the diode should be bad also...and or the filters...im stumped !!!

Thanks for your answer.

But to me it is enigma that the original lcd does not work (works on its original iphone) and a replacement lcd works flawlessly on the iphone which needs lcd to be replaced. And this happens on two devices.

Where is the catch?
