Phone not working (Nothing can be seen)

Dear Community,

after a time I tried to use my old Lumia 1520 again. At first it didn´t work at all, so I bought a new battery and assembled it. Nevertheless the phone did not work. When I tryed to switch it on, nothing could be seen at the screen. The only reaction was a flashing of the three lower buttons. Though I can acess the storage and reset it via PC, nothing is working. In my opinion the mainboard is damaged. Any help concerning a new mainboard or other troubleshooting suggestions would be grateful.

Thanks for the quick response. In my opinion there could be also the mainboard/screen connecction be damaged as sound ( locking, charging) are working. I´ll try your solution.

@count_omega ,Count Omega, Just a thought. Perhaps disassemble the phone and clean all connections(Qtip dampened 90%+ Isopropyl Alcohol) and then reset the connections to be sure of good contact and wires not pinched/broken. While phone is apart use a magnifier to inspect board/components/connectors not(loose,damage,burnt)/solder joints(cracked,etc.) and check that battery is indeed charged. Below is a disassembly link. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
