My phone took water damage and half of the screen is dim even with a new lcd. How can I fix this and if complicated who should I send it to?
First things first, use the teardown to complete a water damage repair on your phone. Once you are done with this, you will need toreplace your screen. Keep in mind you will need to transfer your home button and front camera assembly to the new screen. Be careful with the home button as you will LOSE touch ID if this gets broken. Good luck! (Here is the part: iPhone 6 Plus Screen)
Your iPhone has two lines for the backlight. If you had water damage, one of the lines is probably down causing half of the screen to be darker. You will need board repair. Probably a backlight filter. There probably won’t be a whole lot of shops willing to work on it, because of the water damage.
