    i moved my monitor off of the desk so I could rearrange my desk, I moved it back, plugged it in and now I get a out of range message with a horizontal and vertical (with numbers) below it. (on a alienware running windows xp)
    I hooked it up to my mac to see if it was the computer and the same thing. I hooked up my old monitor and it works fine.
    SO I know it's the monitor but how could it just go out like that? The darn thing is only 6 months old.

There are many areas of the LCD monitor that can cause very much the same effect that you see. Most of the time there are capacitors that go defective.

The caps can be tested with an ESR meter. This is a time consuming job. The caps are mostly surface mount types, and will require the proper tools to change them.

Normaly the service centers will change the defective boards rather than try to service them. There is no component level service support for any of these monitors.

In the end, it would be cheaper for you to replace the monitor rather than to fix it.

I RMA'd this probablem as well. They asked the usual questions -- try it alone, check the connections, are you using VGA or DVI... blah blah. Eventually they could give me an RMA.

They have customer support via phone on Sundays in the US, which is nice. Total time from calling to RMA was about 20 minutes.

Monitor going black after a few seconds can be caused by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.

You need to isolate the problem to see if there's a problem with the monitor or with the sound card of the computer.

To isolate this problem, please try the steps below:

1. Make sure that the monitor is properly connected to the computer.
2. Check the volume of the monitor and the volume properties of the computer.
3. Try to connect your monitor into a known working computer.

dantheman009,
IF you had replace all related caps, usually 5 to 7pcs and still it is not come back to life, you look into the high output transistor area like lotto 50 said. You might also want to check out the ccfl tube is short or not by link them to a good board and try. or you got spare money to order a ccfl tester from china brand.
Check out the manufacturing date from the back of the monitor to determine is worth to repair or not. If morethan 7 years, you can consider buying a new one. The panel will degrade after 7 years and release out toxi gas.
Good luck.

ViewSonic VA1930wm Screen stays on for about 2 seconds, and then goes off. 1) If no computer is connected you get a "no signal" message which stays for about 1 seconds and then goes off; blue...


Very typical of View Sonic. Sounds like a back backlight or inverter. I would go to www.viewsonic.com and open up a RMA. Most view sonic screens have a 3 year warranty. They will repair at no cost ..(if it is within that period) There is a date code on the back of the screen that will help you validate the above information.

My viewsonic monitor goes black after booting up


Does it do the same with other PC?
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed VIEWSONIC monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
