My viewsonic Va1912wb flashes horizontal lines when you turn it on and i know it is not in pal and it is not the refresh trate help me please


Hi There and Welcome to Fixya.

Horizontal or vertical lines flashing/running across the screen poses serious display issues with any LCD/CRT monitors. It only boils down to 2 possible causes :
  • Corrupted video driver
  • Hardware issue
To help you determine which of the above, here's what you need to do.
  • Ensure that the computer is turned OFF
  • Disconnect ALL USB devices except the keyboard
  • Turn the computer on and immediately hit "DEL" (in some systems, it's the "F2") key repeatedly until you reach a different screen. (not the usual Windows screen)
  • Welcome to the BIOS screen
  • From here, spend 30min to 1 hour observing if the lines are present in this mode
If you still see the horizontal lines, then there's a need for the monitor to be serviced by a certified/trained technician. The link below will direct you to their support page for repair/replacement options, depending on your warranty status :

ViewSonic Support

Otherwise, the problem can be resolved by re-installing the operating system.

I hope this helps, Thanks for using Fixya.

Contrast bar comes on constantly and cannot get rid of it. says 1 for exit and 2 for brightness but nothing ever works to exit the bar.


It can be the EPROM is corrupted or it has unstable DC due to bad filter caps like this here: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VX924/

Look for bad caps at the power supply and the logic board.

I have a VA1912wb ViewSonic monitor. Lately, when I power on the computer, the monitor is black, I press the buttons on the monitor, it takes 5-10min to power up.


The viewsonic monitor is a good unit.
If the unit takes more than 30 seconds to power up, you have a problem with the power supply and will have to be repaired.
