Look for bad caps: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VA721/
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, 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.

If the power light is off, have you checked the power cable, or the fuse in the plug?
If thats all ok, maybe time for a new monitor if not under warantee.
It may cost more than the monitor is worth to try getting it repaired

The VA720 I have has 4 screws from the back: 1 at each bottom corner and 2 in the middle lower at the base. Remove screws and carefully pry the front and back halves apart. They snap together. Usually working the bottom apart first is easiest.

SOURCE: Viewsonic VP2030b LCD monitor - No power

There should be one fuse in the power supply inside. You can check and replace that if its dead. now if its not dead and you got power to that point you do need to rule out any capcitors at that time but if the fuse is gone it will not hurt to check the rest of the supply for the fault.

Please rate and accept the answer if it did help.

ViewSonic VA720 monitor will not turn on just a blinking light.


You will need to disconnect the VGA cord that is connecting the monitor to the hard drive. Once you have that disconnected, try attaching another cord to determine if the cord is the issue. If you dont have another cord to test, then you will have to purchase another one from your local computer parts store and attach to determine if that is the issue you are having.

If the cord does not work, then you will have to take your monitor into a repair shop as there maybe an issue with the receiving port on the monitor.

I hope this was helpful and thanks for asking the experts.

What voltage do i need for my ViewSonic VA720


Monitors and PCs (amongst other things) use a fairly standard power cable. You should not need to worry about the specifics as there is generally no transformer needed for a monitor.
