iPhone 4 repair prices

Due to the design of the iPhone, it's most vulnerable part is the display. If the the ribbon cable that connects the display to the logic board is damaged, the whole display assembly has to be replaced. If the display is damaged, it doesn't display any images or the touch panel doesn't function or there is no backlight.

Strong mechanical forces can damage the glass backplate of the iPhone. In this case, replacing the back case becomes necessary.

If the device discharges abnormally fast or doesn't work without plugging it in into the charger, it's necessary to replace the battery.

If the device fails to charge properly or only charges in a certain position, it's necessary to replace the dock ribbon cable.

If the power button doesn't work at all, or only rarely, it's ribbon cable has to be replaced.

If the home button can't sense our finger and the home function doesn't work, the ribbon cable has to be replaced.

If the home button can't sense our finger and the home function doesn't work, the button and it's ribbon cable have to be replaced.

If the audio quality during a call is bad and distorted, this is caused by the earpiece speaker, which needs to be replaced.

A frequent issue with the iPhone 4 camera is visible purple haze on the pictures, which is caused by contamination on the lens. Significant mechanical forces can damage the back camera and sometimes even disable it. In this case, only replacing the camera module helps solve the problem.

The lens cover safire glass is susceptible to breaking because of dropping damage. If the camera module works properly and only the lens cover is damaged, it can be replaced separetly.

If the sound from the earpiece speaker is intermittent or the display doesn't turn off when we hold it near our face, then the sensor cable has to be replaced.

If the touch display gets damaged, the front camera can go unoperational as well. In this case, the front camera, which is located on the sensor cable, has to be replaced.

If sound and ringtone quality is distorted, this is caused by the speaker, which has to be replaced to solve the issue.

If the volume buttons on the side of the phone get damaged, they could fail to function or could create false inputs. In these cases, the ribbon cable has to be replaced.

Dropping the iPhone can damage the stainless steal metal frame or even break it, which can affect cellular reception and other connections as well.

If some iOS functions don't work properly, the system slows down, discharges faster, doesn't connect to the internet - all these can be caused by software problems. Updating to the latest iOS can usually solve these (for technical reasons, going back to previous iPad software versions is not possible).

Before updating to the latest iOS version, we backup your data and then we restore it to the updated device. This is only possible if your device is still functional or turns on after repairs. If the user requires it, we can save some data types to external storage.

Ultrasonic cleaning is required after liquid damage to avoid the corrosion of the logic board and therefore irreversible damage. We clean out the connectors and we resolder them, if necessary. Usually the battery also has to be replaced after liquid damage.

The charge regulator chip is faulty if the device discharges too fast and the battery runs out of charge in a few hours, or if the iPhone doesn't charge while plugged in and won't turn on after running out of charge. This can be caused by bad quality charge adapters or cables.

If the touch screen freezes up regularly or starts to generate false inputs automatically, or doesn't sense touch in some areas, the logic board touch controller has to be replaced. This fault could develop because of mechanical or liquid damage.

The proper functioning of the whole iPhone depends on the power regulator chip, which controls the power and charging systems, the display backlight and giving power to the CPU and GPU. Because of the variety of issues that could be caused by the failure of the power regulator chip - for example the iPad can't be turned on, it gets abnormally warm or the touch screen doesn't work - it has to be properly diagnosed before repair.

The backlight controller usually develops a fault because of overloading after liquid damage. Damage to the logic board during inexperienced repair could cause issues as well.

If the iPhone doesn't see any Wi-Fi network, or the Wi-Fi signal is extremely weak or if it refuses to connect to any network, or if the Wi-Fi and/or Bluetooth options go grey in the Settings app, the Wi-Fi chip on the logic board could be faulty.

If the sound coming out of the speakers is broken up, distorted or if it the volume is too low - and software issues have been ruled out, the audio chip could be faulty. Like all logic board repairs, replacing the audio chip has to be done extremely carefully.

The logic board connectors are very sensitive, so badly trained repair personnel, liquid damage or dropping damage can impair them. Repairing them requires serious preparedness and experience, so it's important to take our device to the appropriate repair center.

The battery logic board connector is very sensitive, so badly trained repair personnel, liquid damage or dropping damage can impair it. Repairing it requires serious preparedness and experience, so it's important to take our device to the appropriate repair center.

A badly inserted SIM card or a bad quality SIM adapter can cause problems, which result in the iPhone not or not always recognising the SIM card. In these cases the SIM controller on the logic board has to be repaired.

The cellular antenna cable usually gets torn during untrained and inexperienced repairs. We replace the broken antenna with a new one.

If the battery in the iPhone wasn't replaced in a proper repair center, the gluing of the battery is often not done correctly and the battery is not fixed inside the device. This could cause the iPhone to randomly power off. We fix the battery in place with the original manufacturing glue.

The interior antenna cable usually gets torn during untrained and inexperienced repairs. We replace the broken antenna with a new one.

We replace the lost or damaged SIM slot with a brand new one, which has the same colour as the case of the iPhone.
