苹果 iPhone 5c 于2013年9月10日发布。该设备的维修与以前的型号相似，需要螺丝刀和撬机工具。提供GSM或CDMA / 8,16,32 GB /白色，粉红色，黄色，蓝色和绿色。
Inverter cable or graphics card issue. Guessing your graphics card was working with the old screen and you installed the flatband cable correctly the cable may have been damaged as pin layout on cable is identical for iPhone 5 to se (and the display frame is different so as yours fit this is certunot a Problem of wrong display type).
Try and disconnect the cable and rotating/ flipping the cable upside down before reinsert.
