3. Contact Apple Care center near you

Do you still see the lines on the phone screen? Well. You’re certainly dealing with a hardware problem. The best thing to do in this case is to contact Apple Care technicians and give them the device to fix. But, if you want to try some DIY options, check out the fixes below.

NOTE: Most DIY options will void your warranty.

4. Fix bad connectors

Check the connection between the logic board and flex cables. Replace damaged connectors and the flex ribbon (if it’s bent over 90 degrees). Clear away dust or debris using a brush and isopropyl alcohol.

When you reconnect the flex cables to the motherboard, make sure the connectors align properly and the ribbon doesn’t bend.

5. Reduce the static charge

Static electricity is another cause for the lines on your iPhone. It occurs when you repair the screen and forget to ground your body. So, your body’s static electricity ends up affecting the iPhone’s circuitry.

To solve the problem, you’ll need to reduce the static charge by wearing a body static remover or touching the ground while doing the repairs. It could take a day or two for the lines to disappear completely.

6. Replace the IC Connector

Lastly, the lines on your iPhone screen after a replacement could be the result of a damaged IC chip. Inspect the upper left and right corners of your display for any signs of damage.

Make sure you get the replacement parts from a reputable dealer.
