Chosen Solution
Hello, I just replace my iphone 6 plus screen. Following the step by step YouTube video after I turned on my phone, I find that the right side of the screen is darker than the left side especially on the top right. I attached a photo on how it looks. I’ve disassemble and assemble the screen before with my old screen but it never happens before. Can someone help me to see is it the screen issue or I did something wrong? Thanks a lot for your help.
Test the old display, to rule that out
If a new screen does not solve your problem, then you probably have a damaged backlight circuit. This may have happened by mis-aligning the FPC connector and causing a short through the circuit. Specifically, check FL2025/FL2026 or the backlight driver IC (U1502).
