Verify that you have turned the monitor power switch on. 4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works). 5. If the power light on the monitor is not on, try a different power cord. 6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced. 7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced.

Does this VX900M version use the wallwart power supply or built-in power supply? Does it do the same when used it with another PC? No signal means it is not getting the video signals from your PC. Wenned to verify if it is PC or monitor problem first.

There are two version of this monitor, one has built-in power supply, another one uses 12vdc adapter.
Adapter:
http://lcdpayless.com/productpage.php?productId=4629

The adapter is REGULATED 12vdc 6a power supply that can handle the load up to 6a, if when is has load on it and the voltage drops down to 2.5vdc, teh it is that the power supply is bad or you have shorted circuits in the monitor. You can test the power supply using 12v car lamp such as #1157 bulb to test your power supply under load.
Caps in the power supply do go bad as you can see in my pictures here:

opening the case will most likely void your warranty.

Monitors don't have replaceable fuses. If its not powering on, then chances are something inside the monitor died(usually because of cheap chinese capacitors) and you will have to try to RMA the monitor with viewsonic, or replace it.

Check all fusible links (such as 0 ohm resistors) and the voltage regulator as well as the rectifier.
You may also have a shorted capacitor, check all electrolytic caps.
