Question about Acer AL1715 17" LCD Monitor
When I turn my monitor on, the screen goes black after a few seconds - why?
More often then not, this is attributed to a failing Backlight Inverter. A Backlight Inverter, is a power board mounted below the screen that actually send power to the Lamp inside the LCD itself. Check to see, when it goes out if there isn't still some images faint in the screen. If this is the case take it to a local repair shop and have them order one and replace it. repair cost for this shuold be around 65-100 dollars.
If this helps, please rate my solution. Have a great day.

I have the same problem on my Acer AL1711. The monitor was out of warranty so I opened it up and found one of the 1000 mf capacitor almost ready to pop. A 50 cents replacement from allelectronics.com fixed the problem.
Not recommended for anyone without experience soldering electronic components to PCB's.

SOURCE: RE:monitor goes black
Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
