In this guide, we’ll explore a detailed step-by-step process for fixing an unresponsive touch screen issue on a 1st Gen iPad Pro. If you’ve encountered this problem, don’t worry; we have a solution that involves diagnosing the issue and making the necessary repairs. Let’s dive into the troubleshooting and repair process.

Power On the iPad Pro

The first thing to try when your iPad’s screen isn’t responding is a simple restart. Hold down the power button until the “Slide to power off” slider appears. Slide it to turn off the device and then turn it back on. If the screen doesn’t response and can’t turn off then follow the next step.

Disconnect the Display

In some cases, a disconnected or damaged display could be the culprit. To check this, you may need to open up your iPad. If you’re not comfortable with this, it’s best to seek professional help. Remove the battery screw on the motherboard and insert a pry piece to isolate the battery from the motherboard to prevent any circuit damage.

Install a Known-Good Display

If after disconnecting and reconnecting the display, the touchscreen is still unresponsive, it’s safe to say that the issue is not with the display. Instead, it could be a motherboard fault.

Inspect Touch Connectors

Check the touch connectors to ensure they are not deformed or damaged. If they appear to be in good condition, proceed to the next step.

Measure Resistance Values

Using a multimeter, measure the resistance values of pin 2, pin 4, and pin 6. The normal value should be around 144 ohms. If these values are significantly different, you might have identified the issue.

Examine the Inductor

Inspect the inductor that connects these pins to the chip. Measure the resistance value of this inductor. If it’s abnormal, the inductor might be damaged, which can happen due to improper operation, such as installing the display with the battery still connected.

Replace the Damaged Inductor

To fix the issue, you’ll need to replace the damaged inductor. Follow these steps carefully.

Test the Screen

Reassemble your iPad and test the touchscreen. If both the touch and 3D Touch functions work properly, congratulations, you’ve successfully fixed the unresponsive touchscreen issue on your iPad Pro.
