I have a va703b monitor that when turned on immediately displays NO SIGNAL then the green light turns to orange and the screen goes black. What's the problem?
That is usually a sign of a video problem, but first you should try to use your current monitor on another computer to see if it works there and/or try to use a different monitor on your computer. If your current monitor does not work on another computer and a different monitor DOES work on YOUR computer, then your monitor is broken and needs to be replaced (I will be utterly shocked if it's the monitor though).
Anyhow, going on the assumption that it's a video issue, Turn off the computer and unplug it from the wall and unplug the monitor from the computer. Now open up the computer tower. There are two things that you can try that won't require you to buy new hardware.
1.) Remove the video card (if you have one) and blow out all of the dust in the computer and off the video card. Look the video card over for any blown capacitors or any melted silicone (it will be obvious what you're looking for IF it's there). Put the video card back in, close the computer and plug it back into the wall and plug the monitor back into the computer and try to start the computer.
2.) You can remove the video card, blow all the dust out, and remove the CMOS battery (It looks like a shiny nickel that is sitting in your motherboard) for a minute or so. HOWEVER, if you do this, your BIOS will go back to it's default setup, which is fine if you never changed anything. Put the Video card back in, put the CMOS battery back in, close the computer, plug the computer back into the wall and the monitor back into the computer.
-------------- If you removed the CMOS battery AND you now have video, you're going to have to go into BIOS (setup) and change the date to the current date and time. (when your computer starts up, you'll see on the screen something like "PRESS DELETE TO ENTER SETUP" at that point press the delete key, or whatever key it says to press and you'll enter BIOS)
If you're still not having any luck, then your best bet is going to be to change out the video card with a compatible video card that you know is in working condition and if that works, then that means you will need to purchase a new video card because your current one is broken.
