    i have same problem screen blinks every couple of secs with display power button blinking cant see desktop screen

    I have the same problem and I've narrowed it down to switching between resolutions. It's not a driver problem, it's a monitor problem. powering off the monitor does not fix it; you must unplug the power entirely. It doesn't always happen. I have had it happen when loading games and when rebooting my machine. Once the resolution changes, the monitor blacks out and will not display an image until i disconnect power to it for a few minutes (normally 5-10 at least but sometimes I've had to keep it off longer). Monitor model is VX922 and it was made Oct 2005.

Look at the main power board. Near the black plug that goes to the audio board you will see a round metal disk with the number 100 on the top. This is a 100uf capacitor. In all likelyhood this is the problem. We recently had 12 go bad at work and we fixed 10 of them by replacing this cap with a $1.29 electrolytic cap from Radio Shack (this cap looks different but works the same). Just remkove the old one and surface solder this one in (pay attention to polarity +leg to + mark on board;)

Blinking on and off is not always a capacitor issue, it is usually caused by faulty transistors at the high output transformers that light the backlights. Crappy board design ! But fixable in most cases.

This LCD monitor is known to die because of heat. I forgot if theese were 100 UF or 1000uf. Take the monitor apart first and then check for the capacitors. They should look a bit werid and buldging out. THoose are teh bad ones. You should get teh uf value correct. Voltage can go higher but no lower. Get the 105 Degrees Celcious capacitors. Choose a good brand such as rubycon , nichon, etc... Google will help you decide. Go to small hobbist electronic stores or radio shack. In vancouver Lees Electronics on 31 and main has a good selection.

I've researched this problem quite a bit and from all I've read, it's a bad power supply. The power supply is faulty and needs to be sent back to viewsonic to be repaired under warranty... shipping for me was about $65 :(

I have a friend that is into electronics, I'll ask him about this capacitor business. Is there a specific voltage of capacitor that needs to be put in the place of the "100uf" one? Are there any other specifications I might want to pay attention to when picking out the capacitor?

I have the same problem, it seems like its overheating. Unplugging it untill it has cooled down is the only solution i can come up with. Its really strange since it calims to only use 40W but still gets so warm.

Same situation for me with VX910, light blinking as if monitor has gone to sleep. The only solution, so far, has been to unplug monitor power for a few hours, and then plug it back in. Not really a fix, but a doable workaround for now.
This has happened three times now, and each time requires the same unplugged waiting period. Did ViewSonic or Microsoft 'update' a driver recently? If so, their bad...

Try to connect your monitor to another PC, if it does the same thing, then your inverter board is bad, or backlight is blown. I can only be definte if you try to connect it to another PC. Let me know! Please!

Monitor blinking but will not come on


most of the time the blinking is a form of error message from the monitor depending on how many blinks in between each pause lets service technicians know which breaker fuse or transistor needs to be replaced
I would suggest taking it into a computer repair store and have them attempt to fix it however alot of the times its cheaper to just buy a new one

Hope this helps

the only thing you can do, is to get a qualified service technician if you are not an electronic expert. because the problem is in your power supply and inverter board. due to heat pressure inside can damage components specially capacitors.

Takes to long for the monitor to start


This is a power supply problem in the monitor. There is an unstable component or components that are failing or you have some cold solder joints in the connections.The reason it turns on is that some components are self healing and will sometimes stabilize after warm-up periods.Cold solder joints sometime close after heating up in the circuit You should return to dealer for repair or replacement. Hope this helps you.

Blue power button flashing with blank screen


This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.
