Question about Acer AL2423W LCD Monitor

Open Question

Broken monitor AL2423W

My 24" Acer monitor has been down for a few weeks now. every now and then after not using it for a while it will turn on and display everything but the next time I turn it on (showing the green power light) it doesn't display anything at all. Sometimes I'll see a little flash from the right of the screen and see part of the "acer" that shows up in the middle but usually not even that. I opened it up and all the capacitors seem to be fine. Could this maybe be a fuse issue?

SOURCE: Acer AL1916W 19" problem

Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

SOURCE: Monitor repeatedly flashes Acer logo and computer display in cycles

We had the same problem with the 17" we bought in Aug. Sent it back for repair. Acer sent it back without fixing the problem. Started doing it again in Nov. This time I called a supervisor and they sent me a new monitor. Well yesterday it started doing the same thing. You can fix it temp buy unplugging it and holding down the on-off switch for 30 seconds. Please let me know if you have a better fix.

SOURCE: AL 1716 LCD monitor has no power when plugged in.

As someone suggested the 3 10 volt 1000uF caps are bad. You can indentify them because they're puffed up on the top and therefore blown. Replace them withj a 25 volt cap 470uF or larger and away you go. I did 4 of them in 3 hours. The case snaps apart which is the hardest part. them remove all the screws you can find, unplug the display from the board, remove the rest of the screws holding the power supply board down, and look for the puffy caps. Cahnge them and put everything back together and away you go.

I had one with the same problem. All the capacitors in the power supply were fried. If you're good with electronics, you can pull it apart and replace them (about 8 bucks in parts) or take it to someone who is.

SOURCE: Monitor Not Showing A Picture. Light flashes Yellow and Green.

use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.

please rate me and give me a fixya! if it helped.

Hi this is prince here from Bangladesh. i have a laptop that is acer travel mate 420. a few days ago its display is not working properly. some times it turn into various color. so what can i do?


Hi Prince, has your laptop experienced a squeeze or fall recently? I have a few suggestions. Plug another monitor into the VGA or DVI connection on your laptop. See if you are getting the same problem. If everything is working fine on the external monitor you would have eliminated the drivers being the problem. I suggest getting the LCD display changed. If your laptop is under warranty, you can get this done for free. However, if it is not under warranty you may have to replace it either yourself or take it to a local Acer specialist. If you chose to install the new display yourself, there are handy tutorials on removing and installing the screen on the Acer website. I have noticed that many times the Acer TravelMate Notebooks have experienced display issues. I hope you get your problem resolved soon.
Thanks for using FixYa.com!!

I have an Acer 24" wide screen LCD monitor. When it sits idle for awhile it puts itself into sleep mode. Usually you would only need to touch the keyboard or mouse & the monitor would revive, a week...


jlichtenegge, Wish all lcd monitor problem descriptions where as good as you have done!!! Here are some suggestions. Use ACER warranty first if valid!!!! If warranty not an option, then do cash+old unit swap for a refurbished same model if ACER has a swapout program for infantile failed units. (short SMPS/CCFL inverter board lifespan) If monitor DOWN TIME is super critical then you or local electronics technician will need to DIY repair unit by resoldering the thermally fractured intermittant soldered to board component lead that is causing "switch-mode-power-supply" to go into full or partial shutdown mode. You may need an inspection grade microscope to visually locate the oxidized intermittant connection. Let me (lmistyrel on aim.com) know what you intend to do fmi Hope this helps. Read more of my fixya profile to get more of a handle on this type of failure. Bye for now.

Monitor ACER 24" stop display after few seconds


This is not a Fix to the Problem, If you read some of the other "fixes" that relate to this you will see that it is a more serious problem and one that Acer should Do the Honorable Thing and have a Recall.
I actually went in side on three of the Same Monitors and one that was a 21 inch and found the problem is "HEAT"
You can see where a Board actually shows Browning on the Circuitry I am Going to try to order a new board P/N:AS08B360411.
I will update as soon as work is completed.

I hooked up my new acer p191w to my dell laptop 1525.HELP!


Not sure what the problem is, but I would suggest pressing the Fn+F5? There is a function key that toggles from dual screen, just the laptop screen or just the monitor. Hope that helps..

Acer LCD Monitor only displays "acer" logo


You are correct, it could be a power surge that has caused it.

Try this..
Unplug the monitor from the wall.
Remove all the video connections at the monitor end.
Wait 10 minutes then plug the monitor back into the wall (do not connect the video leads)

Turn it on and see if it goes past the ACER logo now. If so, replace the video cables and try the computer.
If not, then one of these will apply and a tech will be required..
  1. The internal bios has been corrupted.
  2. The power supply inside the monitor may have issues preventing the video board from starting correctly. This could be as simple as a few failing capacitors.
Number 2 is the most likely cause with an Acer monitor though. Any local tech will be able to correct it fairly cheaply, but phone around for quotes..they can vary a lot.
