Hello,

The domed capacitors are the cause of your power issues. If you replace them you should be back going again. If you are interested we do offer a repair service for $30.00 pus return shipping to repair your monitor.

SOURCE: i have a viewsonic v1716w when turn on it works

The power supply caps will be the first thing to check, then also check for steady 5vdc and 12vdc.
The problem can also be in the T-CON board (part of the LCD panel).

Yes,

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 DELL monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

The screen is black and power led is blinking green


I will assume that you have already tried it on another PC, just want to narrow down the problem before taking the monitor apart.
Most common failure 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 and other monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums

The Viewsonic LCD VA503b when powered on will only give me a blinking power button. Is it in a "power down" mode and if so how do I unlock it?


Is there an ON/OFF rocker-switch (on the side of the screen), with a '|' label on one side, and an 'O' label on the other side of the rocker?

Can you access the OSD (On Screen Display) and run through the various menu items, to control whether the front switch acts as an "ON/SLEEP" versus "ON/OFF" control?

ViewSonc VX924 LCD Monitor


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.
