Re: looking for power cord
That isn't a 'power cord' but rather an adaptor since it supplies DC power from an AC source.
Since you did not include the brand name and model of the monitor, you won't get much help here.
I suggest you find that information and then go directly to the manufacturer's website to look for a replacement.

Many appliances use one of the 4 or 5 most popular cordsets. If you do not have the old cord - you'll have to look at the power connector to determine if it needs a 2 or 3 conductor cord for a line voltage (120V and up) cord and then sketch the opening.
If yours has a small jack - like the types that use an AC adapter to power it up - you'll need to know the voltage, AC or DC, amps or wattage and the connector configuration. This can be as easy as the inside and outside diameters of the plug that is needed - it is almost always expressed in millimeters like this: "5.5mm x 4.0mm", this info may not be readily available - you might need to shop or google:
"power supply adapter (or cord) for <brand> <model> TV".
How do the DC filter caps look? no bulging/leaking tops?
You need to verify the DC output of the 5vd and the 12~18 for the inverter, you will plug the power into the wall outlet and turn off the monitor using the power switch, check the DC voltage (The power supplies will be runing the minute the monitor is plug into the outlet and you do not want the inverter circuits to be running so you can check the DC with the inverter off and on to see if the DC ouput is steady. Please post back what you see.
First place to look will be the power supply section, look for blown fuse, bad caps with bulging top. Take some DC voltage reading on the DC side of the power supply for 5vdc and 12~18vdc. Post the picture will help. See example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
You cannot use a VGA cord to power a monitor. That is the cord that connects the monitor to the computer and is not the power cord. Almost all monitors use the exact same 3 prong power cord. Any computer shop will have a used one on hand.
I had the same problem. In the menu, the image button was grey, and could not be hi-lighted, and the screen stayed blue. I was using the AC power cord. I plugged in the DC power cord instead, and it "woke" the unit up. I switched back to the AC power and it works fine. If you don't hve the DC cord that came with the TV, try andy 12 volt dc output cord with a positive tip.
You will need at least a 4 amp rated regulated 12 Volt power supply. These are commercialy available from most electronics parts suppliers. They come on a circuit board. You can mount it in your own case and use the original Viewsonic wire end. If you do a google search for 12 volt reglated power supplies you should find many of these.
However, with a second-hand Sprint AC adapter with 3A, 12v adapter, the screen blinks on and off intermittently. Obviously there is some difference here between a class 2 adapter and a power supply box.
This monitor requires a power supply with a POSITIVE tip polarity. Monitor requires 12 Volt DC @ 3.3 Amps output. Make sure voltage is 12 Volts DC [absolute requirement]
Power Supply can have greater than 3.3 Amp capacity. More amp capacity increases price, so I wouldn't go for more than 5 Amps [minimum 3300 milliAmps, 5000 milliAmps will be more than adequate].
Put a surge protector on your computer and monitor to extend their life....better yet, a power conditioning battery backup system, that can supply constant voltage, to compensate line voltage when A/C, furnace, or other major appliance kicks on.
