Question about Acer AL2032WD 20" Flat Panel LCD Monitor

4 Answers

Acer AL2021 My monitor works as it is supposed to when turned on, after it has been on for some time, and the computer is rebooted the start up ACER logo flashes on then of after a second or two and the screen remains blank. If I shut off the power for 10-30 minutes the monitor works again and will remain on and work well unless rebooted. Any suggestions what causes this or how it may be repaired. Thank you

    One year after purchasing this monitor, I ended up with the same problem. The monitor would turn on, flash the logo for a brief period (~200ms), go blank, flash the PC screen (also ~200ms), then go blank. Not even the monitor's menu would show when the menu button was pressed.

    I used to be able to fix the condition by unplugging it for a few seconds, then turning it back on. Recently however, a reboot has caused it to go into this failure mode, I fear, forever.

    I tried all combinations of holding keys down, cycling the power switch, even unplugging it. Nothing it seems can ressurect this monitor. I have yet to remove the cover to see what lies beneath.

    If anyone knows which part in the power section happens to be faulty (or even has a suspicion), I would appreciate the info. I would also appreciate greatly receiving a PDF of, or a link to, a (free) service manual for this monitor, if such a document exists; I could then attempt to repair the monitor and post my findings for all.

    I have the same problem with my son's screen and I only bought it for him 2 months ago. It only flashes the logo and then it goes black. I tried everything I know how to do and could not fix it. I am very very disappointed.

    Did anyone ever resolve this? I've had the same problem intermittently with my AL2021 for a couple years. It has recently become much worse--every day I have to hit the on/off button under the monitor dozens of times before I get lucky and it comes on. I've made several calls to tech support over the past two years, and no tech has yet acknowledged that this is a recurring problem with this model, though I've found several mentions of it on the web. I'm finally sending it in for repair.

This also worked for me, On the monitors power supply board, i replaced 2- 470uf 16v, 2-1000uf 16v and 1- 680uf 16v capacitors with ones which were 25v and the monitor works awesome now! Pretty good for a 4.51$ fix and free monitor.

I fixed my AL2021 by replacing the output caps on the power board. $4 repair. Pull the thing apart and replace the 1000uF, 680uF and 470uF caps on the end of the power board.

    Replacing the capacitors worked for me too.
    If your screen suddenly goes black a lot of times just the backlight goes off. You can check this with a flashlight by shining on the screen and watch carefully if you see anything. If you can see anything your monitor is still working only the backlight has failed.

I had exactly the same problem with my acer al2021 - they replaced the power unit and now it's happening again - first the flickering and now no picture at all! and their repair warranty is only 3 months... they told me it would be cheaper to buy a new monitor! so i will - but never another Acer product!

My acer AL2416w monitor turns on to a black screen

I have 2 Acer AL2416W monitors that i have been using for 2 years. There has been a handful of times i would turn my computer on in the morning and the screen would be black and Acer would lightly flash on the monitor 1 time. Typically a restart would take care of the problem. Last week the monitor blacked out and i can't get it to work. Any suggestions?? I switched ports on the computer to verify it wasn't the video card and tried new DVI cables to verify it wasn't those? Is this fixable??

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.

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.

Acer AL1714

OK I have the same monitor, I was given it by a client when I couldnt fix it, I DO have the 19V supply and still getting the same problem.

If you open it and reseat all connections you can reach, I find it starts to work. Unfortunately after less than a few days use it goes off again.

Hopefully this can help someone get further
