I'm in the same boat as well as of this morning. The monitor screen just stays black, not even a "no signal" notification on any of the inputs. Reading around on the internet, a lot of people have had the same problem with this monitor. Looks like I'm going to have to get myself another one [thought not the same model]. I'm not going to wait weeks for it to come back from the repair centre. Of course it would die on New Years' Day when I have no chance of getting a new one until next week!
