I am assuming this is an lcd. Usally when a screen goes dark the back lights are not lighting. This can be caused by

  1. Back light failure (not Likely)
  2. Inverter failing. (most common reason)
The inverter board supplies the voltage to the back lights, it also supplies the video signal to the LCD tab welds.

If the monitor is a CRT, first, attempt to degauss it. if that fails then the cost of repair would exceed the replacement cost.

At start up my viewsonic va1912wb display blinks several times then i can see the picture but it is dark almost unreadable. Today it went darker than yesterday. HELP!


If it is dark due to brightness adjustment, get that adjusted. Usually when you adjust the brightness by pressing the menu button, the menu screen would not be dark. If everything is dark dark dark and you can only see some display but in very pitch darkness, then your monitor is a goner, backlit for the monitor is dead, and your monitor will need to be replaced. You can fix the backlit tubing, however it is risky, and expensive, and would cost less if you bought a replacement.

The Screen is Dark and Cannot be Bright by the Brightness Keys. It Flickers when it first comes on but goes Dark. Can see it if you shine a Flashlight on the Screen. Also the Lid Switch if you Press that...


Assuming all of the connections are secure this is most likely due to a failing LCD inverter which is basically the backlight of the screen. If it's less than a year old cash in on the manufacturer's warranty. If it's not you might as well buy a new one. Hope this helps.
