Hi!I

After replacing the complete appliance front but the unit turns on but nothing appears on the screen, what may have happened?

Nathan The Neko - May 12, 2019

Check if the screen ribbon cable is firmly attached to the motherboard. If it is you may have a faulty motherboard replaced or a faulty screen
