Question about Acer AL2017 20" LCD Monitor

RE:monitor goes black

I turn on the monitor and a few seconds later it goes black. The green light(power light) remains on, showing that the monitor is getting power and signal, but the screen is black.If i turn the monitor off and then back on, it shows the desktop for a few seconds and then it goes black again(the time that the monitor shows before it goes black may vary but most times is about 2sec).If you look really close and carefully to the screen you can see the desktop but its like there is no backlight on the monitor. Can you tell me what is the problem and how to fix it or i need to replace the monitor?

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.

This could be a faulty power supply. If it's an external one then try substituting for another. If the PSU is current limiting due to a fault then it may be dropping the voltage slightly below the backlight operating point but the LCD and power light will keep working. This happened with my Flat panel TV. Alternatively there could be a problem with the backlight inverter.

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

Hi there! You can test first if the monitor is working. Disconnect it from the computer then turn it on after that it should show you colors on the screen this means its working if not then its no use trying it on a different computer.


Hope this helps!

The inverter that turns on the back light may be bad - it's suppose to create the high voltage pulses to fire the CCFL back light lamps. Apparently the back light turns on after a few seconds however, it cannot stay on because the inverter might be bad. If you connect a known external CCFL lamp to the to the inverter output you can isolate the inverter.

Computer monitor flashes on then turns off


Try the monitor with another computer. If it works, the video circuitry (whether it is on-board or a separate adapter) in the Gateway is the problem and needs to be replaced. Otherwise, the problem is with the monitor itself. From your description it is probably the Gateway's video that is the problem since the power light on the monitor remains green indicating that it is seeng a signal, but not something it can properly interpret, i.e., one or more of the control signals are shot.

Sharp light turns green thern turns yellow screen goes black


it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

disconnect the monitor cable from your computer tower
