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.
Can you fix an iPhone screen if it has lines?
Yes, you can. Simply, try the software fixes mentioned above and let the certified Apple technicians handle the hardware malfunctions.
How much does it cost to fix lines on iPhone screen?
The cost depends on the cause of the problem and the solution that helps you to fix it. If it’s a software issue that you can troubleshoot on your own, then your cost would be zero.
Also, if you’re dealing with a hardware complication and you have a valid warranty, the technicians at Apple care can do the repairs at no cost.
For those without valid warranties, the average cost stands at $220. It could be as low as $29 or as high as $330 at Apple as well as third-party technicians.
