Samsung Galaxy pro tab black screen

[Android Central Question]

I have a problem with my Samsung Galaxy pro tab sm-t900. First it wasnt changing and rebooting. We replaced the battery replaced the charging port and got a new charger. After we put the battery in and turned it on. You could hear sounds but no screen display black. Any help would be appreciated

How confident are you that you did not unwittingly do the work badly or incompletely? Confident enough that you don’t think that diagnosis by a qualified repairer would be worthwhile?

Can you get in safe mode? Who did battery replacement?
