No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Green power light comes on goes off then on again stays solid, moniter says no signal, mouse lights up, and three red lights on key board flash then nothing why?


If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

My Acer Al1715 monitor does not display a picture the power is fine as the green light flashes but no picture at all


The light should come on steady. Your monitor most likely has the typical failed capacitor problem. The Power Supply board in the monitor most likely has some capacitors that have failed, visible signs include swelling of the ends of the parts, but they can fail without showing any visible sgns. Replacement of the capacitors often restores operation.

My monitor green light keeps flashing. I cannot get a stead display.


Flashing power light often means the monitor isn't getting a signal. When you turn the monitor off and back on, do you see the viewsonic logo for a few seconds? Try plugging it into a different computer to see if it comes on.

If plugging it into another computer doesn't work, it may be a bad power circuit in the monitor. A common problem with monitors is the capacitors going bad. If you're handy with a soldering iron, you can try replacing them yourself. Look here for pictures and instructions: Fix an LCD Monitor
