How do you removed the battery? Sometimes you can get an pry damage with batterys change

Do you have backlight? Try to see if you can see anything on the screen with some light

Hi, Try first replace the charging cord if not ok try a another battery

Hi, If its just when you plug the charger try to check simple things. Do you have another charger? If yes try it... After that maybe some problem with the battery (That problem happen all the times or just some times?) Start check the simple things first. Best of luck

Hi, Add you put the screews on the right place? That usually happens when the screen is replaced because some people change the screews and damage the streets under it. Sorry about my English.
