Question about ViewSonic VX910 19" LCD Monitor

1 Answer

VX 924 There is the VX910 difficulty that sounds the same as mine. Someone said it is power supply that can fail. It worked fine until the power switch green led started flashing at about 1 cycle per second. When this started to occur, it seemed like it was for no real reason or event. It started to work a couple times, but it seems like it does not want to do that any more. i assume it needs a repair.

Re: VX 924

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?

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:

I have viewsonic vx910.It does not seem to have any power.what do I check in the power supply? is this something I can fix HELP!

carl_p90, I don't know what you are capable of doing in the matter of "checking" the unit's "switch-mode-power-supply/CCFL voltage INVERTER circuits"!!! I have responded to another VX910 that you should read first. (kimespinoza Nov 04, 2009) The only option I did not mention to her was to do the visual inspection for the possible FAILED electrolytic filter capacitors on the SMPS/inverter combo board! Visit YOUTUBE for cilps of "LCD monitor disassembly" and "LCD monitor repair" videos. The longer ones are more helpful! Also check out to see what is involved in doing your own repair work if you discover BAD CAPS in your unit. Then get back here if you need some assistance. Tell us more about your VX910 such as age, approx total "on" hrs of use, and results of doing the "FLASHLIGHT TEST" that every LCD owner should know how to perform when encountering a non-sleep-mode BLACK-SCREEN of DEATH!!! I will be checking for a comment from you after you do some research on your problem. Here is a clue!! Do you own any of the NEW style CURLIE-Q screw-in CFL light bulbs! Same technology lights up your LCD PANEL!!! Only you have thin, straight lamps hung on rear of your panel. Bye for now. 12fixlouie

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.

I have 2 2006 VX910 LCD display monitors no display at all


You have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

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!

Keep blow fuse on power supply board, viewsonic vx910

Replacing the fuse twice is OK but going beyond that doesn't make sense.
I don't know where the fuse is located in the circuit, AC input or some output point.
If it is the main AC fuse, the main power supply is probably faulty and one needs some experience to locate the shorted component.
If it is on the output side you have a shorted part and the above admonition applies; you need some training to know what you are looking for.
If the supply is on a separate board as is common, look for a part (assembly) number and do a search to see if there are companies offering repairs on that supply; if not, you may get stuck buying a new one and there is no guarantee that the supply didn't fail for a reason. You could have a 'downstream' problem that killed the supply.
