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.<\/p>\n\n\n\n

Power On the iPad Pro<\/strong> <\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Disconnect the Display<\/strong> <\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Install a Known-Good Display<\/strong><\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Inspect Touch Connectors<\/strong><\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Measure Resistance Values<\/strong> <\/h2>\n\n\n\n
\"iPad<\/figure>\n\n\n\n

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.<\/p>\n\n\n\n

Examine the Inductor<\/strong> <\/h2>\n\n\n\n
\n
\n
\"\"<\/figure>\n<\/div>\n\n\n\n
\n
\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

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.<\/p>\n\n\n\n

Replace the Damaged Inductor<\/strong> <\/h2>\n\n\n\n

To fix the issue, you’ll need to replace the damaged inductor. Follow these steps carefully.<\/p>\n\n\n\n

Apply a middle-temperature solder paste and continue heating with the Hot Air Gun to lower the melting point of the bonding pad.<\/p>\n<\/div>\n\n\n\n

  • Remove any remaining solder with a solder wick.<\/li>\n\n\n\n
  • Source a replacement inductor from an abandoned board and solder it with the Hot Air Gun at 330\u00b0C and airflow 2.<\/li>\n\n\n\n
  • Clean the area with a PCB cleaner.<\/li>\n\n\n\n
  • Measure the resistance values again to ensure they are normal.<\/li>\n<\/ul>\n<\/div>\n\n\n\n

    Test the Screen<\/strong> <\/h2>\n\n\n\n

    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.<\/p>\n\n\n\n
