Viewsonic VA1912WB.

I get a brief flash of my BIOS boot screen and then the monitor goes blank

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.

Viewsonic LCD?
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 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.

Half way through pc posting screen goes blank Viewsonic VA1912W LCD Monitor


Common failures in this monitor is the 470uF caps in the inverter section (close to the inverter transformers), but you should replace all the caps in the 5vdc and the 12vdc as a whole set. See example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Veiwsonic VA1912WB flashes then goes blank


Hello,

You have a very common problem that happens to many LCD monitors after 2-3 years of use. Your monitor has blown the power supply that controls the backlight bulbs. Go to our web site at: www.ccl-la.com/badcaps.htm and look at the pictures of what blown capacitors look like. Open the back of your monitor and replace any of the parts that look like the ones in the pictures and you should be back going again. Be sure to usehigh temp (105c) replacements. Resolder them in with the side polarity stripe going the same direction and the old one came out. The values of the bad parts will be marked on the sides of the ones you take out, they can be ordered online from us or several other places, the one from Radio Shack are not suitable for use in the high heat inside on the monitor and will soon blow again.

I hope this helps, if so please rate my solution.

If you have more questions just ask.

No display on Viewsonic VA1912wb


Your monitor sounds like it has gone bad. Cost for a repair is not worth it, a new one would be cheaper. Prices have gone down a lot in three years

ViewSonic VA912b monitor fading out during boot


It is probably the power supply, or the inverters.

Similar problem with solution, though it requires you to know something about electronics.

Viewsonic va1912wb monitor goes blank for few seconds and comes back and this happens very often


Your power/inverter board needs to be overhauled.
Your capacitors on the board are probably burned out.
If you open it up and send me a picture , I may be able to tell you if they are or aren't.
There is also a chance a transistor has gone bad on the board.
I repair many viewsonic boards on ebay
