Question about Acer AL1912B 19" LCD Monitor

Monitor display My monitor has started to turn on and off while using my computer. When I shutdown the computer the monitor light will go from amber the standby mode to either green or completely off. These symptoms exist even after disconnecting the monitor from the computer. I am thinking I will be needing another monitor. The frequency of these on & of episodes varies from every few seconds to once every 15-30 minutes. Any solution will be appreciated.

Re: Monitor display

You have either a short in the cable, or your display screen(if it's CRT) is dying.

I have a acer.x223w when,it powers up the.screem stays black, n i get a blue blinking light on.the bottom

I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?

Let me know what happens with the testing above or if you need further instructions to carry out testing.

Thanks, Jim

My monitor no display and light is blinking

if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .

1. Bad video card 2. Bad video software

To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.

If the light changes to green and back to amber the video port on the tower is bad

Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.

Thanks for using fixya

The on/off of pc monitor (LCD) is blinking.

Most LCD monitor (depends on the brand) power indicator light will either turn from Green to Amber, or flashing Amber, or flashing green, when it does not detect video signal feeding it. So it may be normal with your monitor. Are you haivng problem with the display? If it displays he pictue OK then there is nothing to worry about.

Cant get monitor to turn on

try another monitor -

if it works - go into monitors and remove the drivers.
Re-install the monitor you are asking about.
If it doesn't work -- it has a problem - if it is LCD - you can get a new one or a good used one a lot cheaper then trying to fix the old one.

Best of it.

I have an Acer AL1912 that when you plug in the ac, the green power light will blink for about a minute and a half then go solid. The backlight will come on and you can see a faint ghost of vertical lines...

If it is still in warranty call the manufacturer.
if not give more info May be somthing simple like a cable
shutdown computer unplug then disconnect the video cable on the computer from the monitor, plug monitor back in and turn it on, there should be a display that says no video source within a few seconds, if unit is working properly. shutdown and connect video again and then reboot computer. sometimes it just takes a compleat power disconect to reset things,

Monitor shutdown

Yes adding an AGP video card will likely fix it. Although you try not turning off the hard drive(s) and if that doesn't help, not turning off the System Standby in Power Options.

Another thing to try is open MSCONFIG and stop all start up Items under Selective Startup. If it goes away you need to find out which program is causing the problem.

No display (black) - power light is amber color

The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:

Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.

Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.

Monitor Acer Problem

I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber. When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
