SOURCE: PC starts fine, then the montor blinks and no display. light stays green

This is most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps. Try this as it is a common problem I find a lot. Good Luck.

Hi...there,
It's seems you got a defective DVI card. Try using a VGA cable instead. Have nice day!

The light turning to orange means the monitor is not getting a signal from the computer. Check your monitor cable at both ends and make sure it is in very tight and secure at the computer end as well. Also check to see if the computer stays on when the light goes to orange on the monitor. The power cord for the computer might be loose.

Please read below and look at the pictures of failed VIEWSONIC nd othe monitor before try to DIY repair.
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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Black screen at startup


It sounds like the graphics card or on board graphics is causing the issue, as the external monitor is not working either. Hopefully its a graphics card which can be replaced easily, or there is an expansion slot for a graphics card to be added.
One thing you could try is resetting the CMOS by removing the battery from the motherboard and leaving for ten minutes. Replace the battery and try booting.

Go to Control Panel, (top right View Small Icons). Then look for Power Options. On this page, you'll have the option to leave the monitor on. You should also check "Advanced Power Options". Don't be afraid of the word, "Advanced." It only means "customizeable"

If your mouse isn't waking your monitor, try the keyboard's space bar. I found it works better than the mouse at waking a sleeping computer

Light on monitor is green when turned on, but then turns orange with nothing on the screen. I can hear the computer running though.


your monitor is not recieving a video signal from your pc. check your connection to pc, then check things like bad memory card, etc. sometimes just shut pc on and off a few times clears this up.

Black screen


How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.
