iPhone 7 No LCD/No Backlight, but home button reacts
I have a liquid damaged Iphone 7. I replaced one of the LCD connectors since some pins was burned .
The liquid seemed to be on the lcd flex, and connectors, and not all over the motherboard. Therefore i have not preformed any ultrasonic cleaning yet.
There is no picture on the LCD and backlight is dead, but the phone vibrates when i touch the home button. I have tried to ghost type the lock code, but the touch screen seemed unresponsive (no vibration after failed attempts).
Does someone have any experience where to begin fault finding, or known components that fails after similar damages ?
