The phone screen alternates between flickering in a light magenta shade and displaying vertical lines. Phone is completely usable, just now with shades of color tossed in the mix. Sounds to me like a damaged LCD cable, but I haven’t taken it apart yet. I’ve worked with electronics repair, just not iPhones. Point me to a guide?
You may need a new screen or take the screen off and examine the connection cables of the ribbons and mother board. If the brass teeth are not perfectly aligned GENTLY drag a razor blade tip along then to realign them and CAReFULLY reconnect them
This could just be down to dirty contacts, you can try gently cleaning the contacts with a toothbrush whilst checking if any of the contact pins are bent or not aligned, you have to be very careful not to damage any of the pins.
Took phone into Telstra and even they were dumb ass dumbfounded finally gave me new phone but I want to fix the other
