I used my RaspPi as a automatic testclient. After a while, the OS crashed and it's not bootable anymore. But thats not the main problem.
I need the Raspberry somewhere else. I changed the location and tried to start it, but every screen I use doesnt work, it's just in the Standby modus.
I also tried to use both connections, DVI and VGA, still the same problem. Then I tried it on my old screen, there it works. I don't know why, I tried every option in my screen settings, I also tried the manual way to choose an input.
Does someone know a solution?
