Bad power supply. The light is green when it is not plugged into the monitor because there is no load on the power supply. When you plug it in the monitor tries to draw current, nothing the PSU can handle now, so the light blinks. The PSU can not provide the amps that the monitor needs.

Get a new power supply, you can find them on ebay. Just make sure the voltage and amps match. It is ok to buy a power supply with a higher amp rating, the monitor will only take what it needs. Also make sure the power plug that plugs into your monitor matches.

ViewSonic VX910 monitor has a power supply issue.

Your monitor have a bad condensator in the PSU.

The only thing to do is to replace the Power Supply Unit (very expensive, more than a new monitor) or if you have electronic tools, found and replace that condensator.(cheaper way...)


Have you connected your monitor with a new power cord ?

Best Regards!

Monitor light: green yellow green yellow etc.

Cycling of the power LED (about once per second) is typical of a switchmode PSU shutting down and trying to restart. Often this is accompanied by a tick each time, from the main switcher transformer.

Assuming you can open the monitor up (with the power OFF of course) check all the capacitors in the PSU for signs of leakage or bulging. Ideally you would check them with an ESR meter, but they are usually visibly failed when the monitor acts like this.

Replace any defective caps found and try it again while you have the case off, keeping your fingers well out of the way.

Monitor Not Showing A Picture. Light flashes Yellow and Green.

use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.

please rate me and give me a fixya! if it helped.

Flashing green power light - Black screen

I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard

Flashes on then goes black

The green light only lets you know there is a valid video signal reaching the monitor. If the green light was not "on" your problems would possibly be within the pc itself. Something is not holding the circuit for the backlight "on" thus going black. Suggestions are: 1. Take it to get it repaired (if not under warranty) Hyundai carries a 3 yr warranty on this monitor. Website provided. 2. Buy a new monitor

Bank Monitor problems

Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card. If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.
