iPad touch screen is a serious issue nowadays. Parts that don’t initially work as intended are often deemed “defective” right away, when in reality some simple troubleshooting often solves the issue. Taking the time to run some simple troubleshooting during a repair can save you time, money and the hassle of returning a working part back to your supplier. If you’re having issues during an iPad repair, such as a discolored iPad LCD, and you can’t figure out what’s going on, take a look below. You might find the answers you need! If you have yet to embark on repairing an iPad, iPad Screen Repair is a great place to start!

 

Tip 1: replacement iPad digitizer not working properly.

  If the iPad digitizer is not working properly you may have a defective part, but further troubleshooting is needed to confirm. The issues you need to know:

1. Dead spots on the touchscreen: A good way to test the touchscreen is to download a drawing app and draw on every inch of the touchscreen to ensure that there aren’t any dead spots.

2. The phantom touch syndrome · a ghost in the iPad: This is just as common as dead spots on the touchscreen, but is harder to spot in testing. The best way to test is to turn off the auto screen lock feature in settings and let the iPad stay on the home screen. Watch the iPad for 2-3 minutes or let it sit off to the side for 15-20 minutes while starting another repair. You’ll know if the iPad has “phantom touch syndrome”, it will magically open apps on its own. Or the iPad will mysteriously swipe to another page on the home screen. Yeah, it’s freaky!

If the iPad you are troubleshooting shows any or both of the issues listed above, follow these steps:

1. Hold down the power button & the home button for 15 seconds until you see the Apple logo. This is rarely the solution for a digitizer problem, but it is always a good first step in troubleshooting the iPad.

2. First check to make sure the digitizer ribbon cable is fully inserted & that no dust particles are in the ZIF (Zero Insertion Force) connector. Use a can of compressed air to remove dust particles, and then reinsert the ribbon cable into the connector. Make sure the cable is inserted all the way. The white line on the ribbon cable should line up with the edge of the logic board connector. Then you can lock the small black tabs in the down position. Re-assemble the iPad & test again.

3. If steps 1 & 2 have not fixed the issue you may have a defective part. Disassemble the iPad and replace the iPad digitizer with a new part. Then test again. If you have the same problems with the replacement digitizer, then you may have a damaged connector on the logic board.

 

Tips 2: LCD on iPad is very dark.

  If after the repair the iPad screen is dim then you will want to follow these steps to reset the LCD backlight.

  1. Make sure the iPad has a charge – First you will need to make sure the iPad has a charge. Connect the iPad to a computer to see the charge level in iTunes. Once you have confirmed that the iPad is powered on you can proceed to the next step.

2. Do a hard reset – Hold down the power button & the home button for 15 seconds until you see the Apple logo. This is a simple step, but one that many overlook. This can solve many software and hardware issues and should be the first step in troubleshooting the iPad.

3. Re-seat the LCD cable – If step 2 does not solve the iPad backlight issue, you will need to first power down the iPad. Then disassemble the iPad and reinsert the LCD ribbon cable into the logic board connector. Repeat steps 1 & 2.

4. Replace iPad LCD – After completing the previous steps and confirming that the iPad does show up in iTunes when plugged in, then you should troubleshoot by replacing the iPad LCD. If a new LCD does not fix the issue, you most likely have a damaged iPad logic board.

 

Tips 3: discoloration of iPad LCD

  If the iPad LCD exhibits strange colors, vertical/horizontal streaks, or other abnormal display issues, follow the steps below to troubleshoot the iPad.

  1. Do a hard reset – Hold down the power button & the home button for 15 seconds until you see the Apple logo. Again, this may not fix the issue, but it is always a good first step in troubleshooting the iPad. If problem persists, move on to step 2.

2. Re-seat the LCD cable – First, disassemble the iPad and then re-seat the LCD ribbon cable into the logic board connector. This will often fix the issue if the LCD cable was jolted loose from a sudden jolt to the iPad.

3. Replace the LCD cable – Replacing the entire LCD panel on an iPad is a costly repair so make sure that the LCD cable is not the problem. Note: This step only applies to the iPad 2.

4. Replace the LCD panel – If the previous steps do not solve the issue, you will need to test with a working iPad LCD. This step should fix most all LCD discoloration issues. A discolored iPad LCD is rarely associated with a damaged logic board.
