ViewSonic VX922 monitor - black screen - green power light flashes

Could someone please tell me what's wrong with my ViewSonic VX922. I've had this monitor for about 1.5 to 2 years. It's been working perfect until couple of weeks ago.

In the morning, the monitor seems to work fine. I can switch it on and off without problems. I can change the resolution and refresh rate. The only thing I can't do is change the input type from Digital to Analogue. If I try to do that using the OSD on the monitor, the screen goes black and the green power light begins to flash. The only way to bring it back to life is by unplugging it for about 10 seconds and then plugging it back. Other than the inability to change the signal from digital to analogue, the monitor seems to work fine if I don't touch it. I can even switch it on and off and it works fine.

Now, after about 6 hours of use, this is when things start to go really annoying. If I switch off the monitor, change resolution and refresh rate, change the input type from Digital to Analogue, the monitor screen goes black and stays black (even the "no signal" doesn't appear on the screen). The green power light begins to flash at a rate of about once a second. I have to unplug it, wait and plug it back to make it work again.

When I do get it to work in these situations (by unplugging and plugging it back), it works fine for hours on end, I can play games like Crysis, Call of Duty, Counter Strike Source with no problems all night long without problems... As long as I don't do any of those things I mentioned that result in the black screen and green flashing power light.

I think the problem only occurs when the screen resolution and/or the refresh rate changes. And that too, after about six hours of use. Maybe it's a temperature problem but when its working it works fine for as long as I leave the display switched on.

This problem is re-occuring. It happens every day.

I've tested the monitor on another PC and it gives me the same problem.
I've checked all the cables, connectors and pins, and they all seem to be fine.
I have Vista, Geforce 7600GT and all drivers for all the hardware are updated.

    Orignally, I had said that the "black screen and green flashing power light" problem occured after about 6 hours of monitor use. Maybe I didn't test it hard enough. The problems seem to occur after a couple of hours since first use daily. Once the problem has begun, then there is no stopping it. It keeps occuring everytime I turn monitor of, change resolution, refresh rate (which usually happens when loading a game or switching user accounts in windows). I have to unplug the monitor and wait quite a while to bring the monitor back to life. Still trying to get an RMA.

    Same issue here 19" VX922.



    If the monitor is set to 60Hz it works, if it's anything else, it blacks out and power switch blinks.

    hey guys i m so sorry to hear that, ihave the same monitor and spend good money on it first it seemed like system was turning the monitor of fafter like six hours,even after i configured the energy setting , had it monitor never turn off only screensaver after 4 ,min.And i leave for 24 hours i come back lcd green lightr flashes ggoing to move the mouse nothing happens.the waty i used to solve this problem which been accuring about sicne end of last year, used to pull the jumper reset on my board and then plug in the analog and then after i gget a picture again would switch to digital after i reboot, but no nothing works, and i so pissed!!

    SAme problem here, i can get it to work on a analog cable on a laptop after doing a routine of pulging in and out cables and turning the monitor on at the right time but come on! I am so pissed off, I will never buy Viewsonic again.

  • Conquerz Oct 05, 2008

    Hello everyone. I thought I'd just reply to my own problem and state that I rang up viewsonic here in UK and got a replacement monitor that is working. :) (although the new monitor they sent me has about 12 dead pixels which show up on a full black image... but that's another issue I'm trying to resolve with viewsonic!)

    n3lvf2003, thanks for the detailed info on fixing the monitor. If my monitor failed again and viewsonic won't do a replacement, I'll know what to do. I have some electronic background. However, it would be nice if you could post a circuit diagram or a screenshot of which capacitor you replaced so that we are certain in what we do, instead of replacing a wrong component and damaging the monitor further. Thanks.

    I have the same problem started from 2 days ago, except my monitor is a vp930b (more expensive model). I suspect this problem has to do with changing screen resolutions because the coincidence is remarkable. Before about 3 days ago my monitor was 99% of time in native res, then I started playing a game and for prolonged periods of time is not in native res as the game doesnt support it. Coincidence I am now unable to turn my monitor on after its been turned off for a while (in my case overnight), I tested it by turning it off for 10 seconds and on again and that works, when it doesnt work I get the slow flashing power light so sounds like exact same problem. It also happens if I leave the monitor powered on but let it go in standby instead. Initially I thought no problem its in warranty, but it seems what you guys are saying is they exchange it for a used reconditioned unit meaning there is a decent chance you will get something in worse condition back.

  • kulewicz May 14, 2009

    I just received my VX922 back from Viewsonic. It was the same one I sent them. They did not however send back all the cables, driver disks even though they required everything be sent back to them. After doing some research I have found that the problem is in capacitors in the power supply of the unit. It seems that some manufacturer of caps produced a batch of bat ones that have shown up in items built 2-2.5 years ago. These caps over heat and start to bleed. This fix left my monitor seemingly less bright than when it left. I will install the correct drivers and see if that changes things. Good luck to all.

PLEASE read Carefully so here is a fix for the green blinking light ...the monitor is going into shutdown....protect mode......THIS is ...Only for the seasoned electronic service tech ......YOU NEED TO BE into Electronics ..or have electronic background and know how to solder to do this........I been doing repairs for 30 years now ..............After extencive troubleshooting and replaceing a lot of electrolitic caps on the inverter board and spending about 10 hours doing so ....i decided to eather go for broke and blow this up more or trash the unit......................Well my blinking light deal went away...my monitor you could see it trying to start and just shut down............first of all make sure you have no broken solder work on the inverter board or swelled up caps ...Thay use lead free solder so the solder work sucks also...........I did pull the main buss line from the inverter pc board that runs the transformers to test to see where the trouble is.....found its at the high voltage end of the inverter board and The viewsonic 922 uses a protection ic on the inverter board and it tells the controll ic whats the High voltage status of the inverters.....I soldered a 47uf @ 25 volt cap on pins 7&8 of ic-u2 [ bi3101a ] Pin 7 is posivtive pin 8 negative of the cap.... and then soldered pins 10 and 11 togeather on the other side of the ic.......ITs fooling that ic telling the main controll / protect line thats all is well........I would guess the whole deal is LOW inverter voltage or maybe a surface mount device thats going to go........could be low resistor tolerence also............The monitor been working for a week now.........Always on.....anyways........YOUR problem may just be bad solder or bad caps...........if you Have a electronic background or have a friend that works on electronics have him look at the caps.see if any or swelled or rounded on the top of the caps..Also chect the main plug that goes to the LCD backplane to make sure its in correctley................if all that checks then the problem is ON THE INVERTER BOARD ONLY ......befor doing what i have done......I also have a Viewsonic VA-800 that had some of the same problems also ,but it had a lot of lines on the video.......I replaced the,,,,, 2.2 mic @ 50 volt cap in the middle of the main board on it and its still running.....but has about 3/8 of white traces following all the words on the desktop...[[[ anyone that knows this fix i would like to hear from ]]] ..........NOTE if you dont know about electronics...dont attemp any of this......their is a lot of voltage on the inverter board........my answer is that these monitors are JUNK...poorley built units.....

I suggest everyone try an RMA. You don't need a receipt or anything. As long as you bought it within 3 years I think you're good to go for the RMA. Kind of a pain, but it's worth it.

I work at a university and we have had this problem with at least 10 units. I strongly recommend against purchasing this model. We've had to RMA every one.

Nice to see I'm not alone with this problem. So you're saying the warranty is three years? That would be nice because I keep reading people saying "Get an RMA, get an RMA" and I'm thinking, yeah  but what about older units?
This monitor has been terrible. I had it replaced three times when I first got it because everyone had this issue of the top third of the screen getting progressively darker the closer t the top of the screen you get. They never sent one that had uniform image quality and I just gave up. 
Now there's this issue with the flashing power light. But on top of that, Im getting burn-in up in that darker area I mentioned above! I didn't think that happened anymore!!!

I had exactly the same problem so I contacted Viewsonic (by phone) she took all my details but said that no monitors were currently available but they would be in touch. Two days later they contacted me with my RMA reference and said a replacement would be with me within 2 working days. It arrived the day after (Today). Cant really grumble about that for service.

But....

The new monitor is exhibiting exactly the same problem (although not as bad as I can switch between some resolutions) but the most annoying thing is this replacement reconditioned unit has dead pixels which mine I sent back certainly did not. Guess I will be on the phone again tomorrow.

I am having the same problem now. Blinking green light and black screen. Usually I get it if I have the monitor turned off for an extended period of time and then turn it back on. I RMAed it 3 weks ago and got it back yesterday. I woke up this morning and the problem is back so I RMAed it again and demanded a shipping label which they gave to me. The first time I had it sent to their Kentucky servicing center. This time I sent it to one in California. I'm fed up with it and will probably get a new non-ViewSonic monitor.

Posted on Apr 09, 2008

Looks like no soluation except getting replacement for this same problem. At least it seems like this problem surfaces within the 3 years warranty period, as is in my case.

Posted on Mar 16, 2008

Got an RMA number within 24 hours of first email, they sent courier to grab old one in 2 days, and replacement arrived within 6 days of original being picked up with no cost to me. Very happy with that. Also all dead pixels fixed!! Yay!!

Posted on Feb 21, 2008

Yup same problem, replacement monitor just as bad and customer services terrible. Never going to buy a Viewsonic again.

Posted on Jan 26, 2008

Same problem. RMA it if you can. That is if you can get Viewsonic to give you an RMA number.

Their support is horrible right now.

Posted on Jan 24, 2008

This is a common problem with this monitor. I have the same monitor, and my problem started back in September. I simply had to request an RMA and send it in for repair. I never did figure out why it did this, but I got my LCD back and it's working fine now.

SOURCE: My Viewsonic VX924 monitor is not working on the DVI input.

Open the monitor, examine the circuit boards. Look for small components that look like small cans, these are capacitors. If you see any that look bulged on top, then your problem can probably be solved by replacing these. Check out the following sites;

Viewsonic va1912wb-3 has solid green LED but a black screen


Hello,

This is a very common problem on this series on monitors. The problem is caused by filter capacitors in the power supply board that have failed. You can rebuild the board and the monitor will be as good as new. Here is a link to repair information for the VA1912wb monitors.

Viewsonic VX922 19" - green


Since you hadd confirmed that the monitor is faulty with a swap then it seems that the input signal processor is faulty.
Only a signal test will confirm the fault in the stage , so check from the power supply section to see if the set has tripped off due to a protection- if so check the output drivers.

Green light flashing on and off and computer screen will turn on when feels like it


The flashing green power button is a well known electronic problem with this (and other) Viewsonic LCD monitors. There is YouTube video (do a search) showing how to disassemble the VX924 (very similar to the VX922) and find out whether the problem is related to blown capacitors. When I took my VX922 apart I discovered 6 bad capacitors out of a total of 7 on the power supply circuit board.

VX922 monitor, blank screen, blinking power light



If there is a flashing led on front of the monitor, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1 The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours, sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr suddenly are a blown capacitor on power board, the inverter board powering up backlight lamp has blown, or a fault on main lcd controller board.
check also the video cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact Viewsonic to find out a Viewsonic service point.

If you want to repair at your own expenses, just locate any good qualified repairer.

Viewsonic Monitor problem, blinking LED light, no picture.


you guys......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:

http://www.tomshardware.com/forum/247964-33-viewsonic-vx922-monitor-black-screen-green-power-light-flashes

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.
