Viewsonic VX922 19" - green

If your ViewSonic LCD monitor has stopped working with a blinking green power button, It typically means that there is one or more failed capacitors in the monitor. It would be best to send the monitor in to Viewsonic for service or to purchase a new monitor.

disconnect all the cables from the monitor except the power cable and turn it on if still the same issue the monitor has gone bad.

look inside for bad caps, see example of failed Viewsonic monitors here: http://s807.photobucket.com/home/budm/allalbums

You should have 5v and 12v in the power supply sections.

it seems that there is a problem in the lcd back light or may be in power supply section

Change yor keyboard. If any one key remains pressd or if any pin is bent then evrything seems to work but there is no Display and no beeps or error messages either!......i too suffered the same once................sodeep

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.

Check the information at Viewsonic's website regarding their warranty:

http://www.viewsonic.com/support/warranties/limited-warranty/

If you have your proof-of-purchase and it shows the monitor is less than a year old, it would be covered. You would need to follow the procedure on their website to have the unit repaired or replaced, but it would not be your job to try to fix it.

Bad caps, see : http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20V912B/

thanks alot mate!

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.
