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.

Does it make sense to remove the chips shielding following the instruction? At the whole phone I couldnt recognize any damages.
