Display not working, no startup sound after screen & frame replacement
I just replaced the screen & frame on my xperia Z3.
The screen doesn't turn on & there is no startup sound.
When i press power it vibrates once but the screen doesn't turn on, after a while a white notification led starts blinking periodically, once a nofitication sound even went off (it was set to no sound on messages & mails),
When I connect it to pc via usb cable it sees it but cannot Access it... it asks to set to mtp which i cannot do since the screen is off/dead.
Doublechecked all the connections... to no avail...
