Power supply components are failing.

Hello,

The most common cause of a flashing power light is a shorted power supply board. The filter capacitors on the boards go out and this causes the board to not be able to start up correctly so you get the flashing power light. The board can be repaired by replacing the defective capacitors. Here is a link to a kit you can get with the proper capacitors to d the job.

Very typical of View Sonic. Sounds like a back backlight or inverter. I would go to www.viewsonic.com and open up a RMA. Most view sonic screens have a 3 year warranty. They will repair at no cost ..(if it is within that period) There is a date code on the back of the screen that will help you validate the above information.

OSD and Power Lock Settings
• OSD Lock: Press and hold [1] and the up arrow 􀁓 for 10 seconds. If any buttons are
pressed the message OSD Locked will display for 5 seconds.
• OSD Unlock: Press and hold [1] and the up arrow 􀁓 again for 10 seconds.
• Power Button Lock: Press and hold [1] and the down arrow 􀁔 for 10 seconds. If the
power button is pressed the message Power Button Locked will display for 5 seconds. With
or without this setting, after a power failure, your LCD display’s power will automatically
turn ON when power is restored.
• Power Button Unlock: Press and hold [1] and the down arrow 􀁔 again for 10 seconds.


Well this Should resolve ur issue

Try put off Monitor uplug power cord and the VGA cord for 1min and reinsert and restart your PC.

Yes, they are on the front of the screen. There should be a volume up and down button right on the front (usually to the left of the power). If there isn't a separate up and down, try the Menu or 1 and 2 buttons.
