When we pressed the Home button, the device will not turn on.
Before digging into the device, try to turn the device off and wait for 10 seconds, then try turning the device back on. If this does not work try again several times. If the device still will not turn on, try to charge the battery, it could be the device may just be dead. If the device still does not turn on, check the charging/power cable for any physical damage, attachment or orientation.If there is any physical damage, the charging cable needs to be replaced since it is not providing sufficient voltage to the battery, consequently affecting the device power supply.
If the device does not turn on, it might be due to a drained and bad battery. The contents of the battery may have also caused the battery to swell and in turn, causes the battery to drain quickly or not even charge. In this case, the battery will need to be replaced.

If the display screen is not connected the user will need to solder the wires back together. If the screen has stopped working all together, the screen needs to be completely replaced.
Cracked Display Screen
If the screen of the device is cracked it is more than likely that it is only the glass screen and not the actual touch screen display. Because of this the user will not need to replace the touchscreen display. However, the glass is not able to be replaced since it is attached to the body of the device.

Problems related to the motherboard might be a power failure or a component failure. The first action the user should take will be resetting the device back to the original factory settings. If this does not work then the user will need to open the device and check the motherboard for any sign of physical damage such as; burning, broken connectors, or dirty chips. If so, unnecessary peripherals such as SD card and Sim card need to be removed to check the dis-functional device. If the physical damages are able to be cleaned then that should be done; however, if not the motherboard might need to be replaced. If one of the peripherals is not working the entire motherboard will still need to be replaced since it can damage other components.
