    jordyn298, do you see anything on the black screen? May need to point bright flashlight at screen (1 inch) and look very closely for faint image on the lcd panel. Tell me what you see or don't see. Is unit in or out of warranty? May need to ask Viewsonic if "cash+old unit" swapout is option for you. Is your pc functioning ok with substitute monitor? Are you playing "high speed graphics intensive" games" 12fixlouie

Look for bad caps with leaking/bulgting topd first, worst case will be the lamp assemblies.
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 (they should be replaced in a set), 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 VIEWSONIC 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.

Is it hooked up with HDMI cable?

If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.

Dell Inspirion Laptop Screen Randomly Flickers, Then Blacks Out


not to get to concerned just yet, a few tips, when you press on the top of the laptop case by the screen area in the back of the laptop do you notice the screen flickering off? and when you let go dose it come back on? if so this can be a faulty wire or bad inverter, they are actually both very simple to fix and relatively cheap fixes.
