It probably has dying power supply due to bad DC filter caps, see pictures of fails VIEWSONIC due to bad caps at my Photobucket.com.

Vx1932wm-led background lighting goes out


That is a very common symptom of a failure in the power supply board. This model uses the same power supply board that the VA1930 model uses. Here is a link to repair information that shows what capacitors to replace on the power board to repair it.

The screen goes black, if i turn it off and back on the screen will come back, sometimes for a while, sometimes not


Check DC filter caps for leaking/bulging top in the power supply.
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 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.

I have a Vx1932wm that goes to black. If I turn it off and then back on I can see the my log on scree for a sec then it goes black again. Plug in a new VS monitor and it works without any problems. Any...


The problem can either be bad caps in the power supply, or bad parts in the backlight inverter circuits, worst case will be bad lamps. See example of failed VIEWSONIC due to bad caps: http://s807.photobucket.com/home/budm/allalbums
