The short answer, replace all of the capacitors. They can be bad without swelling. And there may be one 47mf/16v off to itself, if it fails, monitor will not come on. Also, check the menu or mode setting to make sure your VGA/DVI agrees with the cable if the monitor has both.

What if the speed LEDs on the VR2/VSI begin to flash?

  • Determine if the battery charger is connected to the power base. When the battery charger is connected to the power base, a charger inhibit feature keeps the power chair from driving. This is indicated by the VR2/VSI speed
    LED(s) flashing.
  • Determine if the charger harness fuse has blown. A blown charger fuse can cause the charger inhibit to
    activate.
  • Determine if all controller connections are plugged into the power base properly. If the 3-pin charger
    inhibit connector is not plugged in properly, then the charger inhibit feature will activate.

Acer AL1713 flashing power LED


Take the monitor apart, and replace any swollen electrolytic capacitors. If that doesn't help (and it probably will) then check for bad soldering and resolder any joints.

But if the capacitors are swollen that will almost certainly fix your issue.

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.
