Question about ViewSonic VX910 19" LCD Monitor

Open Question

Viewsonic vx910 display does not stay on.

When you turn the monitor and computer on the display will show the video for about 1 second then go blank. When the video changes to the windows start screen it comes on for 1 second then goes blank again. If you plug and unplug the video cable, the video is displayed about 1 second then goes blank each time you plug it in. A different computer gives the same results. Both dvi and vga inputs give the same results.
The video appears normal for the short length of time it is on but continues to blank after about 1 second. Any suggestions. Schematics would be a big help, but I have not found any readily available source.

SOURCE: viewsonic vp912b lcd display will not DVI

The problem is the @&%#* windows SP2 and SP3. I have a Dell Monitor 1907Fp and an ATI Radeon X300 and neither works well the DVI out.

But I discovered a method that works in both ATI and NVIDIA video cards.

1. Open Device Manager (Control Panel -> System -> Hardware)
2. Expand Display Adapters
In my case: ATI Radeon Series X300/X550/X1050
ATI Radeon Series X300/X550/X1050 Secondary
3. Disable -> ATI Radeon Series X300/X550/X1050
4. Restart PC

Doing this, Windows works with extended vga setup including in the same card. By disabling the device Windows does not load drivers that are creating the conflict because it does not send signals to the monitor and it goes into rest mode (saving energy).

The downside of this solution is that the card is working in basic mode, because drivers are used to activate the advanced features of the card, that is, performance in gaming or video editing decreases notoriously.

I hope it will help you in something.

SOURCE: ViewSonic VX910 monitor has a power supply issue.

Your monitor have a bad condensator in the PSU.

The only thing to do is to replace the Power Supply Unit (very expensive, more than a new monitor) or if you have electronic tools, found and replace that condensator.(cheaper way...)


Have you connected your monitor with a new power cord ?

Best Regards!

Monitor turns black after 2 seconds, Viewsonic VX910

Check the power supply first for bad caps, then check to see if you do have 12vdc feeding the the inverter circuits, worst case will be the lamps, see example of failed VIEWSONIC monitors due to bad caps:

My screen turned black and began flashing.

Kim, The LCD display requires WHITE light so you can see all the colors on the screen. Most BLACK screen problems will be a power supply problem internal to the monitor. I monitor is still under warranty, have Viewsonic repair it. Here are a few more options that could be available if unit is out of warranty. 1. Trade in for new widescreen display. Please note that the electronics technician at the store will evaluate your monitor and try to repair it for less than $10 in parts! He or she will keep it as a spare unit or sell your monitor for $40 - $60 to a buddy that needs a spare or second monitor. 2. Check to see if Viewsonic has a CASH+old unit swap-out program. They ship you a REFURBISHED same model unit w/ 30day warranty. Yes! They will REFURBISH your old monitor and ship it to another customer. But that's only if a swap program is in effect! 3. Check with a local TV/LCD monitor repair shop, to see if they refurbish LCD monitors with new or rebuilt "switch-mode-power-supply" / "inverter supply" / "cold-cathode-fluoiescent-lamps" . 4. Most costly option. Buy new display AND have your VX910 repaired and kept as spare unit! Before you do any of the above mentioned options visit (FYI) YOUTUBE and search for and view the longer (8-12 minute) video clips of "LCD monitor repair" and "LCD monitor disassembly" to learn what the most common causes of LCD BLACK SCREEN failure are and what parts are used to fix them. Also visit and , for more information. If your VX910 falls into the FAILED CCFL backlight catagory get back here to fixya and let us know what option you will persue. If this was helpful to you or someone else, rate this response on fixya. 12fixlouie by for now.

LCD monitor problems.


If the monitors use seperate plug in power supply EG 12 to 24volts it could be that at fault.
Or it could be the invertor at fault.
I have had some success repairing invertors if you can use A meter remove invertor Panels & check accross the coils with meter set to ohms all the coils should read identical chances are you will find one set of windings either dead short or open circuit. This will be the faulty coil hopefully as your monitors are all the same make the coils will be the same.
Carefully desolder faulty coil & fit one that reads good from a doner board.
Look for any SMD type fuses & check or replace them & thats it I have done quite a few now using this method.
Give it a go.

Is this a flat panel monitor? How long have you had it? What brand is it? Are you getting any type of display when you turn it on?

LCD Monitor has no video

Sounds your monitor has either blown a backlight or the inverter board is bad. Either way they can both be replaced, but tracking down the parts will be a bit difficult. But your LCD Monitor is in trouble! Sorry!
