Dell E176FP Monitor is in ''forever'' self-diagnostic loop. It runs a checkerboard pattern, then a multi-colored squares pattern, then some sort of vertical colored bars pattern, and I think horizontal colored bars pattern, and then a full screen two-part blue that looks like a wave of slightly different shades, etc.. and seems to be running through some preset screen patterns. The problem is.. you can't turn the power off while it is doing this! It does it whether connected to the computer or not.. all you need to do is plug it in.. you can turn it off temporarily if you move it, then plug it in.. the patterns come up, then you can turn it off..ONCE. If you turn it back on again, the patterns come up again, and then you CAN'T turn it off!.. except by pulling the plug. What's up? Is it ''toast''? Need a new one? It's useless at this point. It never stops running those patterns! HELP!
See if the set has some sort of reset button. If none do a hard reset on monitor to hopefully clear the cobwebs in monitor electronics and see what happens.

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.

well that could be because the screen is going bad. you might want to get another one or take it in to get it fixed, no more than 100 to fix your screen.
