My VX922 will come on (for a few seconds) and the green power light starts blinking ? long-on, short-off. Turning monitor off & back on only repeats the above.

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.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Viewsonic monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Check the cable going from the monitor to the back of your PC and make sure that it is plugged in good. Also make sure your tower is turned on.

this problem is adjust not screen resulation on your computer safe mode restert your computer and fress F5 go to safe mode
thanks Tareq

Blinking about once a second? Switchmode power supply fault in the monitor.

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.
See:ViewSonic - Support & Service

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

It may be best to contact Viewsonic about a service manual for this unit and ask to see if that sell any parts for this model.

I have the same problem with my VX922 as do MANY others. The problem seems to be caused by leaking/bulging capacitors on the circuit board. The only solution is to replace the faulty capacitors either on your own (which is fairly easy if you're good with a soldering iron) or send it to Viewsonic and have them fix it.

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:

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.

The flashing green power button is a well known electronic problem with this (and other) Viewsonic LCD monitors. There is a YouTube video (do a search) showing how to disassemble the VX924 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.Only recommended for those handy with a soldering iron.
