Question about ViewSonic VA1912wb Monitor

1 Answer

Screen Display stays on after several times of turning off and on

My Screen Display on the VA1912wb Viewsonic is having issues to start-up. When I leave work and come back the next day I have to spend around 10-15 minutes pressing the power button on and off until the screen display fully stays on. I was wondering if it could be a possible setting that might fix this or a power supply issue. Thanks for your response.

Hello,

The most common cause of this is a failure of the filter capacitors on the power supply board. If you can do a little soldering then the repair is easy to do. You will need to replace the bad capacitors and then the unit should be as good as new again. Here is a link to additional information on which capacitors you will need to replace.

SOURCE: Viewsonic VX900 turns on for second then shuts off

I had to replace a fuse(F1) on the inverterboard of my VX900 to get it back to life as fuzzytek sugested.

It was replaced by a normal "flat" fuse (for cars). Had no clue about the value, so I tried with 0,5A first. It blew right away. Next value I had was 2A, and it worked! (It might be too small, and it might be too big, but I think it is better to usa a "large" fuse rather than no fuse at all. :)

Some pictures from my installation:

Really if this happens then you may want to contact viewsonic to see if it still in warrant. Reminder that most of their monitors have a 3 year warrany from the date of purchase. So make sure that you have your proof of sales/receipt/POP/invoice or what ever you want to call it ready. This model is old so they will ask for it if its a first time repair.

SOURCE: 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.

SOURCE: Viewsonic VG2021m Image Vanishes on Start Up

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a few seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

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.

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.

Viewsonic VA1912WB error says analog signal


I had a Gateway 19" TFT that did the same thing.
Does the power light stay on? If so, you more than likely have "dry" solder joints at the inverters. Take it apart & shoot a little solder on the inverter solder joints. Good as new now. The solder joints dry out because of the high heat generated. This is a very common problem.
