How can I tell if my emachines monitor is the problem or if it's the cord. The monitor (which is about1 1/2-2 years old) all of a sudden quit working so I bought a new power cord (in the meantime I used an older monitor) which worked for about a day but now has quit working also. For a while I was getting nothing from the monitor, but now if I plug the cord in (by the way, the monitor is now in an upside down position) and wait a couple of seconds the blue light comes on. Then it sounds like the monitor switches off and the blue light goes out. Any help will be appreciated! Thanks!
