does that mean that the motherboard also have some problems? Im trying to buy a motherboard for my Note 4 because it has failed. I found a cheap cracked Note 4 for t-mobile for cheap because its cracked. It says that the screen Turns on you can hear notifications and the phone recieves calls but the screen does not light up or work to navigate or answer. Can I buy this for the motherboard ONLY and use it on mines?
