How to Fix iPhone 13 No Graphics Issue: Step-by-Step Solution

Is your iPhone 13 showing a black screen even when it’s on? You may be facing the iPhone 13's no graphics issue. The problem is very common among iPhone users, and there may be a million reasons behind it. In this blog, we will guide you step by step to resolve this problem.

If your iPhone 13 display isn’t working, has no image, or you need help with backlight issues, this is for you. We will explain the graphics IC issue on the logic board. We’ll also learn about how iPhone motherboard repair can help. This iPhone 13 screen repair guide is clear and easy to follow, even for non-techies.

Why Is My iPhone 13 Screen Not Showing Graphics?

The iPhone can work in the background. You might hear sounds and feel vibrations, but the screen stays black. This term means "no display, but the phone is working." Here are some usual causes:

• Faulty Display Connection: The display flex cable may be loose or damaged.
• Broken Backlight: The backlight circuit might be the problem. This would explain why the screen is either dark or has a faint light.
• Damaged Graphics IC: The graphics IC, or GPU, renders graphics. Damage here triggers the iPhone 13 GPU issue.
• Water or Drop Damage: A fall or liquid damage may cause issues with the logic board's graphics IC.
• Software Crash: On occasion, iOS bugs may also cause a black screen.

Now, let us go through each of these to check and fix them.

10 Steps to Fix iPhone 13 No Graphics Issue

Step 1: Check for Basic Functionality

You have to check if the iPhone 13 is switching on before starting any sort of repair. This will help you decide whether it is an issue with the screen or the phone.

• Via any method, call your iPhone. If it rings or vibrates, someone has turned it on.
• Press the power button and listen to the lock sound, along with the charging sound.
• Connect it to a compatible computer. If it is visible in iTunes or Finder, it is working, whereas the screen is not showing.

Your phone has the iPhone no-image problem. There’s no image on the active screen.

Step 2: Force restart the iPhone 13

A force restart might fix display issues if the screen is black when turned on. This step forces the system to reset without deleting data.

• Quickly press and release the Up Volume.
• Quickly press and release the down volume.
• Press and hold the Side button until the Apple logo appears.

Doing this may resolve the display not working on the iPhone 13 because of a system crash. Go on with the next steps if it has not resolved the issue.

Step 3: Use a Flashlight to Check the Backlight

In case it starts but displays a completely dark screen, the backlight may be at fault. Testing this at home will be easy with a flashlight.

• Ensure that you power on the phone, even if the screen looks black.
• Point a flashlight at a slant directly onto the screen to check for a faint image.
• Check for dim icons or the Apple logo. If you see a faint glow with shapes on the screen, the display is on, but the backlight isn't.
• This test checks if the iPhone 13 needs backlight repair. It does not check for a full display replacement.

Step 4: Inspect the Screen for Physical Damage

Sometimes the problem may not be inside the phone but inside the screen itself. Check for physical damage. This can help you decide if the display needs replacement.

• Check for cracks or black spots.
• Examine the display flex cable.
• Inspect the screen connector pins.
• Check for burn marks or smells.
• Gently press the screen.

If the screen is cracked or damaged, the best solution is to replace the display. This is the very first step in any iPhone 13 screen repair guide.

Step 5: Test with a New Display

If your screen is blank, test it with a working display. This will help you check if the problem is with the screen or the motherboard.

• Turn off the iPhone.
• Disconnect the old display.
• Connect a new or working screen:
• Turn on the phone.
• Check Touch and Brightness

If the new screen works, you have, in all probability, a defective display. If the new display does not work, then there is a deeper problem, like the logic board graphics IC.

Step 6: Check the Display Connector on the Logic Board

If the new display isn't working, the issue might be with the connector on the motherboard. A dirty or damaged connector can block the signal to the screen.

• Use a magnifying glass for the inspection of any bent or missing pins.
• Clean it up with isopropyl alcohol and a soft brush.

If the connector remains damaged, it could cause the iPhone 13 to have no graphics. You may need to get help from an expert for soldering a new connector.

Step 7: Identify Graphics IC Problems

If the screen or connectors don’t show an image on the iPhone 13, the problem might be with the graphics IC or GPU chip. This chip controls what appears on the screen. Common symptoms of graphics IC failure are as follows:

• The screen goes black after the Apple logo appears.
• The screen has been replaced, but the image still does not appear.
• The device works on the computer but shows no graphics.

To fix this issue, technicians must repair at the motherboard level.

Step 8: Perform iPhone Motherboard Repair

Now, this one is not meant for amateurs. An expert iPhone repairer skilled in micro-soldering can be very helpful here. What happens next is:

• Someone removes the logic board from the iPhone.
• The microscope displays the graphics IC chip located underneath it.
• A hot air rework station lifts away the heat and the chips.
• Someone replaces the chip with a new one.
• It then gets soldered back onto the logic board.

This is the real fix for the iPhone 13 GPU issue. If you have success, you will once again have your phone show pictures.

Step 9: Fix iPhone 13 No Backlight Solution

If the flashlight test shows a faint image on the screen, the backlight system is likely damaged. To fix this system, first diagnose the issue. Then, repair the backlight circuit on the logic board. The technician should:

• Check the backlight diode, filters, and capacitors.
• Test the backlight coil and IC by using a multimeter.
• Replace damaged parts by making use of a hot-air gun and a soldering iron.

After the repair, your screen will light up as it should. This is how you fix the iPhone 13's no-backlight issue.

Step 10: Test and Reassemble the iPhone

Always test the phone after repairing the GPU, backlight, or display. Do this before you reassemble it. Once you finish the repair, test the iPhone before reassembling it.

• Turn on the iPhone.
• Touchscreen Test
• Check Face ID and the front camera.
• Adjust Brightness Levels
• Reassemble the iPhone.

Align and screw the device back together with precision. Your iPhone 13 screen repair is now complete.

Conclusion
