Apple iPhone 5C and 5S Battery Troubleshooting:

The Apple iPhone 5C and 5S Battery is your main, mobile power source for your device. The iPhone battery is located under your main screen. If your uncertain if your issue is with your battery, plug your device directly into your computer. If everything works while plugged into your PC, but your device turns off right after you unplug it, then you need a new battery. If your device has to be recharged more often then usual, or will not charge at all, then this is the part you need.

1. Try a different power cable on your device. You may have a USB cable that has gone bad at the same time as your battery. This is a fairly common occurrence. If this does not work…
2. Remove your battery, and plug your iPhone straight into your computer. If your device does not power on at all, then you may have a bad charge port. Try replacing the charge port flex cable. If a new port does not resolve the issue…
3. Reattempt the repair from the beginning. Double check all your connections during the installation to see if something may have come loose or was damaged during the original repair. If this still does not resolve the issue…
4. You may have a defective or broken battery.

Apple iPhone 5S Back Camera Troubleshooting:

The Apple iPhone 5S Back Camera is your default camera located on the back of your device under the main screen. If you are experiencing problems such as a fuzzy image or lines through your pictures, you may need to replace your lens instead of your camera. If your pictures look distorted while viewing on your device, but after sending them through an email or download are clear, your screen has gone bad not the camera. If you are having any other problem with your camera, then this is the part you need.

1. If your device is not acknowledging your new camera (your app is blank), you will want to try a soft reset before you reopen your device. A soft reset will clear your devices' cache memory for your old camera, and recalibrate to allow your new camera to work.
2. Also, check the alignment of your camera. If your camera is off-center, then your back housing will block your camera, and give the impression of your camera not working.
3. If your pictures look fuzzy, there may be a protective film over the new camera. Open your device again, and remove this film. With your device open, double-check your camera and camera lens for any sign of debris or scratches. These types of scuffs and dirt can also blur your camera.
4. If your pictures look distorted while viewing on your device, but after downloading them to your computer they are clear, then your LCD screen has gone bad, not the camera. You will need to replace your LCD to resolve this problem.
5. If after this troubleshooting your camera still will not work, you may have a defective or broken camera.

Apple iPhone 5S Buttons (Set of Mute, Power, Volume) Troubleshooting:

The Apple iPhone 5S Buttons (Set of Mute, Power, Volume) is a set of 3 separate parts. These parts independently control your volume rocker, mute or vibrate switch, and the lock or power button. Normally, issues with these parts are due to broken interior flex cables that can also be replaced. These external buttons should only need replacement if the original part has been lost due to damage.

1. Reattempt the repair from the beginning. Double check all the flex cables connected to these external buttons to make certain they were not damaged during the initial fall of your device, or during installation.
2. If all the cables look intact make certain all your cables fit properly. If everything fits, your cables look intact, but your device still will not function properly, this is a sign of something worse then a simply cosmetic issue. We suggest mailing in your device for diagnostic testing.
3. If your buttons won't fit then you have a defective button set.

Apple iPhone 5S Charge Port Flex Cable (Includes Headphone and Mic) Troubleshooting:

The Apple iPhone 5S Charge Port Flex Cable (Includes Headphone and Mic) is composed of three separate parts located at the bottom of your device under the screen. In addition to your main charging dock, this cable also controls your head phone jack and your main microphone. This flex cable also contains a chip that allows your USB cables to sync on your device. If you are getting error messages when you try to connect to iTunes, or charge your device, then you may need to replace this cable as well.

1. Start with checking all three parts of this flex cable. If you are experiencing issues or non-functioning of only one of these three components, then you may simply have a bad flex cable.
2. If your device will not power on after repair, you may have a bad battery in addition to a defective charge port. Remove the battery and see if you can plug straight into a charger to get life. If you do, then you need a new battery.
3. If all three parts don't work, reattempt the repair from scratch. After removing the good part, check and see if your original cable is still functioning as it was prior to the repair. If neither cable will work now, we suggest contacting a member of our support team for further information.
4. If none of the troubleshooting works, you may have a defective or broken part.

Apple iPhone 5S Ear Speaker Troubleshooting:

The Apple iPhone 5S Ear Speaker is your main hearing piece when using your device in normal phone mode. The ear speaker is not the same as your external speakers for playing music. The ear speaker also does not control the sound when using your phone in speaker phone mode. If you place your phone to your ear to answer a call, and you have no sound, then this is the part you need.

1. Make sure your ear speaker is fully covered by the protective plate on your iPhone 5S. The ear speaker on this phone only fully functions once this shield is on. This shield aids to direct the sound outward to your ear instead of inward at the internal components of your device (they don't listen well anyway). If this piece is missing, or nor on correctly, you will need to open your device, and tack it down before your new ear speaker will work again.
2. Check the springs (the copper prongs) on your ear speaker. They are designed to maintain a constant connection on your device, and if one of these prongs is not long enough, you will need to stretch it back into place before your new speaker will work.
3. If your hear a buzzing noise while taking a call, your new speaker simply is not tight in its fitting. Open your device, make certain your ear speaker is aligned correct, and tighten all the screws that hold this part in place. Your speaker now should work normally.
4. If your ear speaker is tight, all the prongs are touching, and the cover plate intact, then you may have a defective or broken part.

Apple iPhone 5S Front Camera and Proximity Sensor Troubleshooting:

The Apple iPhone 5S Front Camera and Proximity Sensor is composed of 2 different parts. The proximity sensor is soldered to the front camera, and the 2 parts cannot be replaced independently. If you are having issues with blurry pictures, you may have a scratch on your fron screen, and may not need to replace the front camera. If your screen will not turn off when you place the phone against your face, then you need to replace the proximity sensor using this complete part.

1. If your new part has reversed the calibration of your proximity sensor (screen turns on when placed to your ear), then it is usually a simply matter of recalibrating your device. Perform a soft reset on your device, and this should fix the problem.
2. The same is true if your front camera will not work, but your proximity sensor will. If your app is not working at all, then again, a soft reset should fix the issue. If the app is working, but there is no image, check the alignment of your camera. If your camera is off-center, then the frame will block your camera, and give the impression of your camera not working.
3. If your pictures look fuzzy, there may be a protective film over the new camera. Open your device again, and remove this film. With your device open, double-check your camera and camera lens for any sign of debris or scratches. These types of scuffs and dirt can also blur your camera.
4. If your pictures look distorted while viewing on your device, but after downloading them to your computer they are clear, then your LCD screen has gone bad, not the camera. You will need to replace your LCD to resolve this problem.
5. If after this troubleshooting, your part still will not work, you may have a defective or broken part.

Apple iPhone 5S Home Button Flex Cable Troubleshooting:

The Apple iPhone 5S Home Button Flex Cable controls your main click feature when attempting to go to your main "home" page. This part is only the internal flex cable, and does not have any control over the finger print reader. If you have all ready activated the finger print scanner on your device, you will need to remove this feature before replacing this flex cable. Once replaced, your finger print feature will not be able to be activated again. If you click your home button, and nothing happens, then this is the part you need.

1. If you all ready activated your finger print reader feature on your device, this new flex cable will not fix your phone. Each home button reader is specifically calibrated to your device. Your best solution will be to undo your repair, place your old flex cable back in your device, and deactivate the finger print feature before reattempting this repair.
2. If your new home button will not work, reattempt the repair from the beginning. Make sure the plug side of this cable is fully attached. It will sometimes come loose when placing your screen back down, and this is block your home button from working.
3. Double check your new cable for any signs of crimps (folding) or rips. This cable can easily be severed during repair. Also, any crimps will create fractures in the thin metal inside the cable. Once this metal is cracked (folded) power will no longer flow through the cable.
4. If none of the troubleshooting works, then you may have a defective or damaged part.

Apple iPhone 5S Power Button Flex Cable (Includes Mute and Volume) Troubleshooting:

The Apple iPhone 5S Power Button Flex Cable (Includes Mute and Volume) controls most of the primary functions of our iPhone 5S. This cable is located at the very back of your device under all the other components, and then laces through to the front of your device. If you are having issues with any of these three parts: power button, mute switch, or volume keys, then this entire cable will need to be replaced.

1. If only one part is not working, one of the connection points may simply have some loose while sealing up your device. Start with reattempting the repair from the beginning, and see if any of the contact points are loose.
2. If none of the contact points are loose, but you still don't have full functionality, double check your power cable for any signs of crimps or rips. Crimps (or excessive folding) can cause a break in the metal that is inside the flex cable. If this metal is folded too much, then your device will not be able to get power or any other signal through this part.
3. If none of the troubleshooting works, then you may have a defective or broken part.

Apple iPhone 5S Screen Replacement (Digitizer and LCD) Troubleshooting:

The Apple iPhone 5S Screen Replacement (Digitizer and LCD) controls both your touch function and your main image display. If your top glass is broken, your touch function is unresponsive, or you have no image display, then this is the part you need. This screen comes with both your top digitizer and your lower LCD fused together for easy assembly. This version of the iPhone 5S screen does not include any additional components such as home button assembly, front camera or ear speaker.

1. If you have an all white or all black display, start by performing a soft reset on your device. Blank and white screens are usually a sign of the internal software not wanting accept the new parts. A soft reset will clear your device of any temporary data that is blocking your new part from working.
2. Check to see if your screen's back light is on. If there is no back light in addition to no display, your new LCD is not plugged in correctly. Reattempt the repair, and make certain your new part is fully installed.
3. If your digitizer will not respond to touch at all, reattempt the repair, and make certain your cable was not crimped (folded too much). Crimping causes micro fractures in the thin metal inside a flex cable. Once this metal is cracked, power and other impulses cannot flow through the device.
4. If only a select grid of icons will not work such as the top third, or left side, you may have a cable that is miss aligned. Open your device, and make certain all the connectors on the flex cable match up. If this plug is off center, you will see problems such as this called "blocking". Blocking can also happen if either your digitizer cable, or your motherboard plug have missing or bent pins. These pins will need to be put back in place before your device will work again.
5. If you see blotches on your display, this is a sign that too much pressure has been applied to the LCD at some time. Open your device again, and make certain there is no residual glass from your original broken screen. After clearing your screen, disable your phones "Sleep mode", and leave your device on a charger for 24 hours. The heat from a constant charge can cause the crystals inside your device to move back into place.
6. If the troubleshooting does not work, or if your screen has lines down your display, then you may have a defective or broken part.

Apple iPhone 5S SIM Card Tray Troubleshooting:

The Apple iPhone 5S SIM Card Tray is an easy replacement if you have a SIM Card Removal Tool. We include both with your order of this part! Our SIM trays do not include any serial numbers like the original tray does. Your IMEI number can always be found under your settings section of your iPhone 5S.

1. If your device will not connect to your service provider, your SIM Card may have worn out, or become demagnetized. Contact your service provider, and get a new SIM Card to see if this will fix the problem. You should not need to change phone numbers to get a new SIM card.
2. If a new SIM card does not fix the problem, the your SIM card reader may be damaged. This part is attached to your motherboard on the iPhone 5. If this part is not working, then it is highly unlikely it can be repaired. Your best solution will be to get a new device.
3. If none of the troubleshooting works, then you may have a damaged or defective part.

Apple iPhone 5S Speaker Dock Troubleshooting:

The Apple iPhone 5S Speaker Dock is your main external audio control on your device. This part operates your external sounds such as ringtones and music. The ringer speaker also operates your devices audio when placing a call using the loud speaker feature. This part does not control your audio when placing your phone to your ear. Your ringer speaker can normally be found toward the lower part of your device underneath the main screen.

1. If your new speaker will not work at all, reattempt the repair from the beginning. On the back of the speaker, there are 2 prongs that make a connection inside your device. If even one of these 2 prongs is not lined up for a full connection, then the entire speaker will not work. This also applies if you are hearing a buzzing sound, or just have a very faint sound as well.
2. While your double checking the 2 prongs on the speaker, also check that your motherboard has not lost it's contact points. If either of these 2 points came loose during the same event that lead to your speaker needing replacement, then no speaker will fix this problem.
3. Also check that your speaker still has a magnetic charge. You can easily do this by placing something on top of the metal area of the new speaker (something metal). If there is no magnetic response, then your new speaker lost it's charge in transit, and will not work.
4. If none of the troubleshooting works, then you may have a damaged or defective part.

Apple iPhone 5S Vibrator Flex Cable Troubleshooting:

The Apple iPhone 5S Vibrator Flex Cable controls your main shake function when receiving phone calls, text messages, or playing games. Unlike other vibrators, the iPhone 5S vibrator is attached to a flex cable that plugs into your main motherboard. No soldering is required. This part is found in the upper left hand corner of your device.

1. If the new vibrator is not working at all, open your device, and reattempt the repair. Most vibrators have only 2 prongs to make a connection. If these prongs are not aligned correctly, then your new part will not work. In addition, make certain your new part is fully plugged into the main board.
2. If your new vibrator is not as strong as it should be, or your hear a buzzing instead of feeling a buzzing, your new vibrator is likely loose inside your device. Open your device, and make certain it is snug in it's fitting. If needed, use some type of adhesive to hold it in place.
3. If none of the troubleshooting works, then you may have a defective or damaged part.

Apple iPhone 5S WiFi Antenna Flex Cable Troubleshooting:

The Apple iPhone 5S WiFi Antenna Flex Cable is your main internet signal receiver on your device. This part is located under your main screen, back camera, and a few protective shields on the iPhone 5S. If you are experiencing problems connecting to a WiFi signal, or have a weak wireless signal, then this is the part you need. The WiFi antenna does not control your connection to your cellular network. If you are having network access issues, take your device to your phone service provider for more information.

1. If you are unable to receive any signal at all, try restoring your device back to factory default settings. Apple devices tend to remember the last part that was installed, and getting a new part to work is simply a matter of recalibrating the device.
2. If you have a weak signal, this is usually due to a loose screw on your device. Open your device again, and make certain every screw is tight. Most of the screws in this device are specifically placed to help boost your reception of both wireless and cellular signals. One loose screw can make for a weak connection.
3. If none of these troubleshooting steps work, you may have a defective or broken part.
