yo i think this subject has been coming up really often but for a few hours i got a problem with my x1. when i boot it theres nothing but a blackscreen. before the x1 worked pretty good, no problems at all. today i turned my x1 off and unplugged the HDMI cable into my ps3. everything worked, but later on when i tried to boot my xbox there was a blackscreen. i literally tried everything i could find on the internet. its not working on other TVs either. so the problem has to be the xbox. i really tried everything out. i unplugged it from the power. first only for a few minutes, then for like 2h, i tried rebooting tricks like for example pressing the power button for 10 sec. etc etc etc. i have no idea what else i could do. but i don think that the xbox breaks when u turn it off and unplug the HDMI cable into a ps3....

ill appreciate any kind of help... thanks
