Question about Dell E176FP 17" LCD Monitor
As soon as display is powered up, some sort of test patterns keep cycling and the buttons do not seem to have any effect except the power button. After about ten minutes, the pattern stops cycling and remains locked on a triple blue gradient pattern. At this point, even the power switch has no effect. The colors are radient so I don't believe it is a power supply problem. This occurs regardless of disconnecting from the computer.
This could be a computer or monitor problem. The reason that display shows up is because the monitor is not getting a power good signal from the computer. If a monitor doesn't get a power good signal it goes into test mode. It could be the monitor has a fault that is not allowing it to detect the computer, or the video card or computer itself isn't functioning properly. If you can, hook the monitor to a computer that you know is working properly. This will tell for sure if it is the monitor or not, and eliminate that possiblity. Then you will know if it is the monitor or computer. If the computer is the problem you'll need more help troubleshooting it.
