Why is there no display?

5 possible reasons you have screen issues and the LCD is not working at all on your device

1. System needs reboot

It could happen because of the device’s software crashing. First, try to reboot your phone by holding the power button and home button together for at least 10 secs.

2. You need a screen replacement

A reason why your phone is unresponsive could be because the screen got damaged from dropping or pressure. In this case, we can make the screen work properly again simply by replacing the screen.

 

3. Battery replacement

Your issue could be due to the device's dead battery. If you come to our store, we can fix it by replacing it.

 

4. Charging connector replacement

It could happen because of the device’s damaged charging port. In this case, we can fix it by replacing a charging connector to the device.

 

5. Mainboard damage

The other reason could be due to mainboard damage.

Q: What is the mainboard?

A: The mainboard (motherboard) is the core part of the hardware and controls all functions of the phone. Every part of the phone with a function is connected to this mainboard.

 

Q: How can the mainboard gets damaged?

A: The mainboard can get damaged from shocks (drops), dropping into water or even from pressure. Also, mainboard damage can also be caused by charging with a poor quality charger/cable. Damage to the mainboard can arise even if there is no physical damage.

 

Q: What happens when the mainboard is damaged?

A: As the mainboard is the core part of the device, once it’s damaged, it can make functions play up. The functions affected depend on the location of the damage.

 

Q: How do I know if the screen’s freezing is due to screen damage or mainboard damage?

A: There is no way to physically find out if the mainboard got damaged or not unless you test the device with a new screen and see if it’s working properly with a new screen or not. With this issue, we can help you through a quick inspection and can tell you if it will be solved by replacing a screen or not.

 

Q: What should I do if it is a mainboard damage?

A: If it’s a mainboard issue, don’t worry because we can fix this issue at Happytel. Most screen freezing caused by the mainboard are related to the mainboard’s 2 touch ICs and our head office technicians can repair this by micro soldiering. Our success rate for this procedure is 85%.
