General Troubleshooting Steps
Confirm you have the right part for your device.
Many parts are very similar, but parts are specific to a device and models. Use our handy guides Find my model# > to look up your model number and then review against the new part. Also you can compare the new part to your original part to see if they are the same.
- Go back over your work. For each step, reseat/reconnect all cables and connections you touched or might have disrupted to make sure they are securely connected. The cables are super-sensitive to being just a little out of place. If the problem is with the display, then check those cables carefully. Cables are fragile so be careful to not bend or pull.
Inspect and clean the connectors gently and carefully attempt to reattach the cables.
Dirt and dust is common during a repair and will disrupt the contacts and cause display issues. Clean the connectors on the logic board and the screen. For cleaning, we recommend using 95% or higher alcohol on a q-tip. You can also use a pressurized air to blow out or if not available a soft bristled brush (like a clean tooth brush).
- Review more troubleshooting below for specific issues and tips.
Last, try reinstalling your old part and see if it works.
If works, contact our customer service team if you purchased from RepairPartsPlus. If it doesn't work or if you have a new problem that you didn't have before the repair, unfortunately you may have accidental damage. This isn't covered by parts warranty, but there are still ways to fix using online resources like Reddit. Experts such as repair shops or online services can also help fix it.
LCD display not working / won't turn on
If that doesn't fix it, it may be the battery was not disconnected properly. Always always disconnect the battery before disconnecting any other cable. With ALL the original hardware/connectors attached, disconnect the battery from the board. Slide a guitar pick between the connection to ensure no power travels from battery to logic board during repair. After all the new connectors are in place, reconnect the battery as the last step before putting everything back together. This can work to get the iPad to accept the new parts.
Start by performing a soft reset on your device. A soft reset will clear your device of any temporary data that is blocking your new part from working.
Touch Screen Not Working
Note: If pins are missing on the digitizer connector plug on the motherboard, we recommend having a local repair shop or an online repair service fix it for you as it requires micro-soldering.
Try all of the following to correct:
- Hard resetting iPad: Confirm iPad is on first. Then hold the Power button and the Home button simultaneously until you see an apple logo appear. (ignore the slide to power off)
- Check all connections, especially the connector leading to the glass digitizer.
Reseat the digitizer cable to make sure it is fully inserted and not pinched. Ensure that it is fully seated within the connector clamps, and the white line on the ribbon cable lines up with the edge of the logic board connector. Lock down all the tabs to secure the cable in place. If the cable shifts during reassembly, it will cause touch issues.
Ensure that when you reapply the glass that you are NOT pinching that cable between the digitizer and the housing, if it is folded or kinked it will give this type of error. This is usually the issue if the touch works well BEFORE reassembling the touch digitizer with the LCD and closing up iPad. The cable to the new glass needs to be tucked in the same fashion it was removed. If this cable overlaps itself, you will see this this issue.
- If this doesn't resolve, then you may have a short-circuit caused when installing the touch screen to the LCD. This is common on iPad Air/iPad 5 and Mini. On inside of glass panel, review the conductive adhesive tape (usually gold) along the four sides. COVER ALL of the gold tape on all 4 sides with black electrical tape or Kapton tape.
iPad Home Button Not Working
* IMPORTANT: Only the original iPad's home button is capable of using Touch Id function. Installing a new home button (included with some screens) will restore all standard functions, but NOT Touch Id fingerprint features. To get Touch Id, you will need to transfer home button from your original screen.
If home button not working after repair or during use, try this to get it to work before you open device. Helps if home button is stuck, jammed, lagging or unresponsive or broken - How to fix a home button issue on an iPad >
Transfering home buttonTransfering the home button from original to new screen is the most challenging part of a repair. Take your time on this.
1. Make sure you have all the components correct in the home button assembly. Here are typical components and position: Glass, spacer, home button, soft gasket then holding bracket. You can transfer or purchase home button components from the original screen including the gasket or spacer and bracket. Use adhesive to secure bracket which holds home button. If transferring gasket, apply a little heat to loosen so you don't tear.
2. Make sure you're also using the plastic spacer ring. It positions the button at the proper depth and helps prevent the edges of the button from catching under the glass. These are delicate so be careful or they can tear. A new gasket may also help to hold button better.
3. Home button not holding. You may need to use combination of adhesive and glue. Clean the bracket and the glass where the home button bracket sits with isopropyl alcohol. Apply adhesive strips on the bracket to secure it. Some repair professionals use multi-purpose B7000 liquid glue (available here or a local store like Walmart) on the left and right hand side edges of the bracket. And let the glue set for 24 hours. Here is an expert video that gives some good tips for any iPad (note: primer is not commonly used) - Transfer Home Button
4. If home button will not click or doesn't lay flat, remove the digitizer, and check for any debris such as broken glass chards near the home button. This is quite common.
New home button
1. If replacing the home button during a repair, and it doesn't work, make sure the home button is on straight. If the home button is crooked won't make contact with both pins. To correct, you may need to take off home button and straighten it.
2. If working with a new home button and having trouble. You may want to go back and transfer the home button assembly from the old screen to the new one.

iPad Mini Home Button Not WorkingIf your home button will not click at all, remove the digitizer, and check for any debris near your home button. The iPad Mini home button does not have any bracket mount to hold button in. All of the home button pressure comes from the metal housing frame of your device. If the glass digitizer is not flush after repair, the home button will not receive the pressure needed to make the button work.
If you can hear a click, but you get no response from the device, double check the digitizer flex cable for any signs of nicks or crimps (excessive folding). The home button flex cable on an iPad Mini is part of the digitizer flex cable of this device. If either cable has been damaged, you will need to replace the iPad Mini digitizer before home button will work.
If the cables look intact, and you can feel the “click” feature, there may be damage on the motherboard of the iPad. You may need to get help from online forums or take to a professional.
Adhesive Not Holding / Screen Won't Stay Down - Popping UpIf the digitizer seems to be popping out of the body near the bottom after screen replacement, it may be the flex cable ribbon is pushing it up.
This can happen if the glass digitizer flex ribbon is bent in the wrong direction when the digitizer is installed. It will cause a lifting pressure on the screen.It's really common when replacing iPad screens, and especially the iPad Mini. When properly installed, the digitizer should lay flat without needing to force the bottom to stay shut. The Digitizer Ribbon will effectively make a sort of sideways W shape. The digitizer should rest flat without having to be held in place. Review a video instructions to see how the ribbon should go.
If the glass digitizer is not laying flat in the corner and is bowing up, then may mean the frame has been bent from a drop. If you press on the glass corner, it can crack. You will need to adjust the aluminim frame to make the glass digitizer fit. Find more on this by searching online.Find more tips on using and securing adhesive here >
