Assumming that you've already replugged in the cables to ensure there are no connection issues...then first, borrow a known "good" monitor and hook it up to your current computer to make sure it's not an issue with your machine.. If the borrowed monitor works, then the Envision may be dead.. But it's still worth taking one more step...
Next, take the Envision to a different known "good" computer and plug it in.. If it doesn't work on the second computer, your culprit is clear.
Hope this helps.
My computer monitor(Envision EN9250)just stopped working on me. It won't turn on and I've used different cords so that's not the problem. What may be wrong with it and how do I go about getting it fixed? Thanks
