When you plug its power supply, the indicator light green color will appear, then it goes out after a few seconds..


If you don't have a computer connected to it that is powered ON then thats normal, its going into stand by.

View sonic monitor VA712 doesn't display picture even after power supply light turns green


It may have blown fuse in the backlight inverter board, that will be the first place to look.
Post pictures if you can.

My VA712 does not turn on, when supply button (mains) not from front panel, switch ON it shows blank screen (no sign of turn on) but when repeatedly switch ON & Off it Turns On & shows the display....


bholesir, If unit covered by ViewSonic warranty, USE IT!!! The units "switch-mode-power-supply" is in need of service!! Unit WILL require inspection and repair of possible bad (poor quality soldering) soldering of electronic components to the prinded circuit cards and or need replacement of bad (poor quality) electrolytic filter capacitors on the unit's "switch-mode-power-supply"/"CCFL inverter circuit" that have failed!! Do a visit to YOUTUBE for "LCD monitor disassembly" and "LCD monitor repair" so you can familarize FYI with what is inside your monitor, and possibly make a decision to do a DIY repair or contract out the work to a local TV/LCD monitor repair shop. If your pocket is deep enough, maybe you will repair and buy a new unit, keeping VA712 as spare unit for a rainy day. Read more of my responses to other owners in my FIXYA profile for more options not mentioned here. Good luck with repair. 12fixlouie

The monitor led is green but it gives white flash and still blank


Check the volatage regulator in the mainboard resolder all you found dried unsolder parts inside mainboard. Voltage test the regulator IC if have a voltage flow 2.5 to 5v DC. check ribbon cable connector from mainboard to controller board if properly connected. In the controller board find the small fuse test it for open.
Reminder:
When you voltage test in the power board
in the primary section of power supply
use hot ground. Do not use the hot ground
when you voltage testing the secondary
power supply, mainboard and controller
because it will cause of damage
semiconductor. For safety use cold ground
for secondary, mainboard and controller
board.
