My monitor will not display anything

Try to unplug it, wait for 10 seconds, and then plug it back in from both ends. Let me know if it works.

@robertj30180 time to open it up and to look at the boards. Check for any obviously damaged components. Could be as simple as a failed component on the power or the video board. Until you look at it and check it out, it'll all be just a guess.

Since iFixit does not yet have a specific guide for this, use something like this video

Once you have it opened up take a good look at teh boards. Post some well focused pictures of those with your question. That way we can see what you see Ajout d'images à une question existante

While you work on your monitor, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
