9 galaxy note 20 ultra Black screen
Hi all
I have a galaxy note 20 ultra, which I have just replaced the screen, been working fine for a couple of days and picked it up this evening noticed it was not on, I tried to turn it on, but there’s no response totally black screen, I have checked and it is a charge, but still no response from the power button. I’ll try to do a force restart but again no response, so I completely dismantled can remove the motherboard cleaned and checked all connectors were firmly in place, but still no life.
Any help would be appreciated.
