Your iPhone screen is turning red and you don’t know what to do. Generally, iPhone screen distortions happen when a display cable isn’t making a clean connection to your iPhone’s logic board. In this article, I’ll show you what to do when your iPhone screen flashes red and show you how to fix the problem for good.
Is My iPhone Broken? Do I Need A New Screen?
At this point, it’s too early to tell whether or not your iPhone is broken. Many times, an iPhone isn’t broken, but has been dropped or jostled in a way that has loosened a low-voltage differential signaling (LVDS) cable from the logic board. Even the tiniest imperfection with an LVDS cable can cause an iPhone screen to flash red. So while your iPhone may look fine, there could be an underlying issue with the hardware.
What To Do When An iPhone Screen Flashes Red
First, we need to rule out any possibility of a software glitch. To do so, we’ll try turning your iPhone off an back on again. Press and hold the power button until the red power icon and slide to power off appears on the screen on your iPhone. Then, swipe the red power icon from left to right. Wait about 30 seconds before turning your iPhone back on, just to make sure it has the chance to fully shut down.
If you turned your iPhone back on and the screen still flashes red, your iPhone probably has a hardware problem. Before exploring your repair options, there are a couple of tricks you can try which may fix the problem.
Hardware Troubleshooting Trick #1
Our first hardware troubleshooting trick for when an iPhone screen flashes red is to press down on your iPhone’s screen where the display cables connect to the logic board. If the display cables are only slightly dislodged, there’s a chance that pressing down on the screen of your iPhone will put them back into place.
Use your thumb to press down directly on the screen where the logic board connects to the display cables. If you’re unsure where to press, use the image above as a guide.
A quick word of warning: be careful not to press down too hard on the screen of your iPhone because it could cause the screen to crack.
Hardware Troubleshooting Trick #2
Our second hardware troubleshooting trick is to hit the back of your iPhone. It may sound silly, but if a display cable is slightly out of place, hitting the back of your iPhone can get the cables back where they need to be.
Make a small fist and hit the back of your iPhone. Make sure you don’t hit your iPhone too hard, as you could damage its internal components.
Both of these tricks are fairly non-invasive, so we recommend that you give them both a try before exploring your repair options.
If you’ve made it this far and your iPhone screen is still flashing red, you probably need to get your iPhone repaired. Fortunately, if your iPhone screen flashes red, or if the screen looks fuzzy, it can be repaired.
