Viewsonic VX2640W was running with the screensaver on,then suddenly went solid white. Turned off for thirty minutes then back on with same result. Unplugged from computer and turned on. Still turn

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

How to remove the back of the Viewsonic


We don't have a guide for that exact model but check our wen site at:, we have repair guides for several Viewsonic models that are very close to that model. If you do find bad capacitors be sure to use LOW ESR replacements that are also high temp, they will be marks 105c. We recommend Nichicon caps. When replacing the caps be sure to insert the new ones with the polarity stripe going the same way as the old caps come out. If you need parts we carry them in stock, email us a list and we will get right back to you.

I hope this helps, If so please rate our solution.

It's an issue with the power supply, most likely the Capacitors (one or more) may be shot. Open it up if it is out of warrenty, look at the capacitors (they look like cans), if they are bulging at the top or even sides they are bad. This is a common problem with this monitor. Crappy Caps used in manufacturing. Replace all the caps with same rated caps and you should be good. Do your research on how to desolder the old ones off and proper installation of the new ones.

ViewSonic LCD Monitor Went Blank

It is probably a bad INVERTER and / or backlight fluorescent bulb.

Drivers cannot be does not recognize monitor

I think after your crash you are missing the drivers for your graphics card and not the display. Check what kind of graphics device you have and see if you can find the drivers for that.

Screen goes white after 12 seconds

Per the first hit on Google for 'viewsonic fades white',;jsessionid=A68BB7FE4AF6EC93EB730E8588C865A2?topicId=4064461903&sid=1
(which you should go on and read in another tab,) you need to contact Viewsonic about an inverter board (for the CCFL backlight) or switching your backlight to LED while spoofing the INVERTER_OK signal to keep the display from giving up as it does.

So...this should be a hint that you should respect others' time (or be moved to increase usability) better by searching for cures in similar Viewsonic monitors, and of course checking the obvious search terms.  Viewsonic evidently has a nifty knowledge base available for all on the web, so that one would be a nifty surprise.

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.

Viewsonic Monitor problem, blinking LED light, no picture.

you don't have a software (driver, refresh rate, etc.) problem. When you first power up the monitor, do you get any display at all (ex, "analog input" or "No input signal")? Of course not - that's because you have a hardware problem with the monitor. Go here and watch the youtube video on how to take apart your monitor and find and replace the "domed" capacitors that have blown:

Fortunately I only had 1 ($1.76 at Radio Shack). I replaced it in less than 30 minutes and my monitor showed "no input signal" upon powerup as expected because I wasn't connected to my pc which is full of all kinds of drivers and refresh settings, etc.
