Question about ViewSonic VA1930WM LCD Monitor

1 Answer

Screen Blinks image on & then goes black.

I turn the monitor on & the image comes on says analog and then the image goes out. Every time you turn power on & off the image comes up for maybe 1 sec. and then goes black.
What really has me confused is it saying analog. Could it be I have the wrong plug? the cord from tower is plugged into D-SUB 16 pin.
there is another receiving port marked DVI (Assuming this is Digital Video In) & it is 24 pin.
Please help

Does it do the same with other PC? I assume you are using VGA DB-15HD cable, not the Digiltal DVI.cable. It can be failed component inside the monitor but you need to narrow down the problem first. If you are going to DIY repair, please read below and also look through the failed VIEWSONIC monitors so you will know what to look for inside.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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.

The Screen comes on for 1 second then goes black but you can still faintly see the image on the screen


It can be as simple as bad DC filter caps (leaking/bulging tops), that will be the first thing to look for, it can be more serious problem in the inverter circuits or bad CCFL assemblies.

The monitor turns on and the computer image comes on for about a second then screen goes black again. The image that does come on is perfect.


I'm having the exact problem. I just got the new monitor & I replaced my 18". When I plug it in it flickers, when it does come on it's clear & clean; but after a few minutes it goes black. I tried to switch it to Digital & Analog, but I don't know how to fix it. I know it works, it was just plugged into my brother's computer. Is something wrong with the settings on my computer? If so, how do I fix it? I have both monitors hooked up on my computer desk right now, it's a bit crowded! PLEASE HELP ME!!!

A 20" monitor gets a black screen when turned on


sounds like you might have a back lighting issue? take a flash light and shine it on the monitor when it is black and look to see if the image is there but not lit up, if this is the case then you might need to change the light balist in the monitor of even the back lights themselfs..
if the picture is fuzzy for a long period of time then you have a controler card issue there is a controler card in the monitor that changes the image coming in from HDMI, VGA, DVI into the binary that the vertical and horizontal drivers use to show you the image onthe screen... hope this info helps. good luck

SyncMaster 932B blinks, then screen goes black


Check all the connections and if they are all right and tight then the monitor is probably shot. The good news is that it can be repaired. It's usually around $50.00 to $80.00 to fix. Good luck!

Monitor goes black after running for a few minutes. Brand new 22 inch sceen.I prees the button to turn it on and it says Analog and goes black again. I have to shut down the computor to get it to come back...


Sounds like the computer is shutting it down and the monitor is fine. Check for viruses then check your settings in device manager for the screen saver and power down (screen off) options.

Toshiba satellite a135 monitor goes black


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I have a shap lcd computer monitor and when i plug it into my computer and turn the power on, the little green power light comes on, screens back. and after 5-10 seconds the light turns orange and blinks...


It could be your monitor is fine. It simply goes to a cycle when its turned on and does not detect any signal coming from your CPU, it simply goes on standby mode (hence the darker image and orange/blinking light.) have you checked the computer (CPU) part?
