Acer AL2002W Monitor problem

Something happened to the monitor. It was originally plugged into a desktop computer. It stopped working. It will turn on for about 1 second, then go black. I unplugged it from the desktop and put a different monitor in its place. I now have the Acer monitor hooked up to my laptop just to try and test it, and its doing the same thing. I can turn the monitor off for a few seconds, then turn it back on and see my screen from my laptop, and then it cuts out. im using D-SUB cord to hook it up to the laptop, because i dont have a DVI-D cord or port on my laptop. I have seen a message that said check DVI cord or something like that. Does anyone have a solution?

    It said check VGA cable (i think the last word was cable) then the light next to the power button went from green to orange (which i believe is power save mode according to the manual.

    The only difference between turning on the monitor when it isnt connected to anything and when it is connected to my computer, is that when it isnt connected to anything, it will go into power save mode. when it is connected, however, the light stays green.

  • Tekken05 Apr 06, 2008

    correction to my last comment. It said check DVI cable not VGA

  • Tekken05 Apr 19, 2008

    Ok. I know i can fix it if i know what part may be broken. Ill check it out sometime this summer when i have free time from classes. Thanks for the help.

  • Tekken05 Apr 30, 2008

    Thanks for the specs. Ill be sure to look for one at the parts shop here on campus.

    SAME AS Tekken05. I originally had hooked to an HP Compaq Presario and was to use this with a spare desktop. I bought a SOYO for main computer Now when I attempt to hook up the ILO to any computer ( ( repair some desktops for friends) the only thing that happens is green light flashes Anyone have the link to download owners manual for this??

  • Tekken05 Dec 15, 2008

    I just put in the new 450V 100 micro Farad capacitor and it still has the same problems. So I'm assuming there are other capacitors on the board that are bad. Does anyone have an idea on which ones might also be bad? I am going to continue to look and see if I can find any others are have gone bad, but if anyone has an idea of which ones they have replaced, please let me know. Thanks.

  • Tekken05 Sep 16, 2009

    No, it was not solved. I don't know whats wrong with it. I tested the voltages going to the other board. They were all 5V DC as described. I didn't check the 4 connections to the screen itself. I'll have to check that later.

    Try turning it on without hooking it up to any PC and let it run the power on self test.

    Does it do the same thing?

A monitor that flashes on for a second and then turns off is a sign of a bad capacitor, or multiple bad capacitors.  If it is no longer under warranty you can fix it for a few dollars at the electronics store.  Unplug the monitor, pull the back off.  Look for the capacitors.  They are the round water tower looking things.  The top of the bad ones will usually be bulging, or leaking.  (the top should be flat).
Grab a soldering iron, and be sure to note the polarity (there will be a dash on one side of it, like on a battery) so that you can put the new ones in the same way.  Putting them in backwards will likely toast the monitor so get this right.  heat up the solder joints and pull the capacitors off.  Take them to an electronics store, and buy new ones. ( the capacity and voltage need to match. 12V 500uf  ... something like that, match the numbers on your capacitor(s) not the numbers I wrote here!
grab your soldering iron again, and making sure to use enough solder, but not too much put in your new capacitor(s).
I hope this is helpfull to folks.

I have a 19-inch Acer AL1917W LCD monitor with that exact same problem. Mine is out of warranty. The problem is a bad capacitor on the power supply IC board inside the monitor. My problem is a stupid lock at the back of the monitor; it takes a special key to open that lock.
There are quite a few small (cheap?!) electronic devices with such a problem (the symptoms may be different on different equipments but the cause is the same bad power supply capacitors). The root cause was a bad batch of capacitors from China. The end-product manufacturers, like Acer, Pansat, Mitsubishi, Sony, etc) know about this problem but will not admit to it, nor fix the problem unless you bought an after-market extended warranty.
I have already repaired a few equipments with this problem. Anywhere from 1 to 3 capacitors may go bad at once. Radio Shack sells those capacitors (420 to 470 micro faraday); less than $4 bucks for a pair.

    Hello again folks,

    I have fixed my 19-inch Acer LCD monitor. The problem was indeed a bad capacitor. It was a 450 volts, 100 micro farad; the only capacitor on the power supply IC board. That high voltage capacitor was hard to find but I found one at an electronic surplus store. It cost me $8.50, plus $2.00 toll and 40-mile worth of fuel (round trip).

I have an acer aspire m3400 is start but no sound, no display graphics plz help me.

Try another monitor. If that works, download the latest drivers for your OS here...
If the old monitor still doesn't work, here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Monitor no signal acer M1640

Check the cable at the back of the monitor and at the back of the computer. If the cables are in tight and you still get the no signal error message you either have a bad monitor or a bad video card in the computer.

Try plugging another monitor into the computer (borrow one from a friend, neighbor or family member if you don't have one). If the monitor does the same thing and shows a no signal message like your original monitor, then the Video Card in the computer is bad. If the monitors works, then your original monitor is bad.

Monitor will not boot up is reading no input signal

So either the computer isn't generating a video signal, the cable isn't carrying the signal to the monitor, or else the monitor isn't capable of receiving a video signal.To test this, first try a video cable that you know is good, in case your cable is bad, If it works with the other cable, the problem was your original video cable. If it still doesn't work, put your original cable back, and hook another computer up to the monitor. If the monitor makes the same message, the problem is with the monitor. If the other computer works when connected to this monitor, your problem was that the original computer isn't booting (which could be due to several reasons I will list below), or the video adapter is broken.Possible reasons for the computer not booting: bad power supply, bad power button, bad hard drive, bad memory, bad motherboard component. If you determine that it isn't booting, unplug everything except the keyboard mouse monitor and power cord, to see if that makes a difference. If it boots after that, something you unplugged was causing the problem, plug them each back in one by one, rebooting in between, and when it stops booting properly, the last thing you plugged in is causing the problem.

My acer al2002w monitor will turn on then go blank. I cannot see any icon even with a flashlight. Do you know this problem?

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

For DVI you need to probably upgrade your cheap graphics card, something not that expensive would be a ATI Radeon HD2400 Pro, it'll do. May want to check what pwer supply maybe required on your PC.
