Phone does not activate the screen any more at all

Hi, my FP2 Screen showed wired collors and then went off for good. Even during loading no screen activation took place. I ordered a new screen but its still the same. Only the load indicator is working, switching from red to yellow after a short time. For the screen is now brand new and i cleaned the contacts, are there other common errors lead to such behaviour? My fear is that the main controller might be damaged.
Addition: 1.) The phone reacts on power on button with common vibrations.
2.) My computer shows the contact to FP2, even the files can’t be accessed for I can’t use the screen to accept sharing. (Are there ways to cantact file system without using screen?)


You might try to access the files after starting #dic:recoverymode (while connected via USB data cable to PC).
