Question about ViewSonic VX922 19" Monitor Flat Panel
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.
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.

Some other brands inc. dell is power circuit transistor components

The problem could be the same as with my brothers, it´s the power circuite for the image handling circut thats has 5 conductors that failed for some reason(if the top of the cann is´nt flat it has failed) I just ordered 5 new ones for 3$

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.
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.

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.

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!!

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

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.

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.

Only true Solution is get your 30-06 and use this monitor as a target

Yeah Im once smiling again and my brain and eyes arent hurting anymore thanks to my new viewsonic vx922.Viewsonic just replaced my monitor now everythings is back to normal ,Mark my words lets see if this one holds its life expectation over the warranty exceet limited.And for anyone having the troubel with the monitor just make sure u with in the warranty time of purchase and, call viewsonic they will rma.Another thing when u rma keep the cords and the installation software.
Viewsonic customers service was very nice and Accommodating .!!!

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;
Follow the directions and good luck!
