I own a 3 year old Asus MX279H. So far working perfectly but the other day I saw the screen like flickering (was googling).
I tried changing the cable to the second HDMI, with other HDMI cable and on the VGA input. Everything was the same.
The next day I couldn't turn it on. Well, in fact I could but I could only see the led which was white (turned on) but if I try to select some inputs on the screen I can't see anything either. So no signal at all on the screen.
The power cable is an Asus one so I can't test it with another monitor but as long it has the led turned on I think is ok. What I tried was the other extension of the power cable (the one you need to connect to wall).
Also tried connection other laptops and it didn't work.
Need to say that the PC works without problems on another monitor that I've got (and using now).
So my question here is if I can fix this by myself.
