Is my Galaxy Note 4 dead? Black screen – won't charge or turn on. Since it appears to be dead, I can't get it to do a soft reset, hard/factory reset. Tried removing the battery and waiting, discharging the phone by holding in the power button, and even bought a brand-new battery which I fully charged overnight in an external charger and there is no response. The little charging light at the top left corner never comes on. Even tried doing all this with the SD card and SIM card removed. I also tried charging from a USB port on my computer and did receive a connection tone from the computer but the phone still did not charge and does not show in Explorer. Is there any hope and can it be repaired, or does it pay? I love the phone. Many thanks in advance.
