According to repairing experience, the problem of white
screen is very likely to be caused by CPU, EEPROM
chip and Nand Flash Memory. In addition, the customer
has straightened the iPhone. We can conclude the empty
solder or welding joints drop on CPU may cause the
problem. Therefore, we should reweld the CPU.

disconnects. Besides, the other circuit is not stable either,
