Hello, I have to same problem. I returned my monitor to Acer but got it back unrepaired, they could not see the malfunction. But I kept on sending it back, until I got a new model. Now after 2 years I get the same thing with this monitor. But there's no warranty anymore, so I looked into the problem myself. I found out that inside the powercircuit board is connected to the mainboard through a 10pin connector. The 5 pins that are on the lowest row, show a trace of white powder, I suppose occidation. I sprayed a little of contactspray in it. I must say the problem is not gone, but much better. The problem shows not so frequent anymore and lasts not so long. At first the screen switched of for 3 to 5 minutes and came back on. Now the screen is gone for perhaps 1 second and returns. So I'm almost convinced the problem has something to do with the connection of the powercircuitboard inside and the mainboard inside, when the monitor heats up a bad connection occurs due to occidation of the 10 pin connector. If you find a solution that fixes the problem 100% let me know, please. Mario.

Acer AL1711 17" LCD Monitor showing white screen


A white screen indicates the power supply board is not putting out the correct voltages to properly power the monitor, just the back light. This type of issue is caused by a failure of the filter capacitors on the power board. You can rebuild your power supply board and bring the monitor back to life by just replacing the the bad capacitors. The problem is that model the Acer AL1711 could come with 1 of 4 different power supply boards install depending and the date manufacturer and supply on hand. If you want to repair the monitor if you could open the unit and get either the model number of the power supply board or send a picture of the board to me I will be glad to help you repair the unit and get it back up and running. You can contact me to send the information at

Hi, i have an acer lCD monitor model x223w, the screen light flickers for a few seconds then the moniter shuts down. what can i do to fix it?

if no any power led indicator at the front panel after of shut down, the cause could be power supply failure. you will need to remove the back cover to gain access of the internal part of the monitor. look for a blown fuse or burnt parts at the power supply board. if you have an idea about electronic parts just replaced defective parts with the same rating and value. hope this can help good luck just let me know if you need further assistance.

Sudden failure - working fine then next time switched on no apparent power (no indicator light on), no display

You could have a power supply problem in the LCD monitor.
First check the power lead, make sure it is firmly inserted into the mains socket and into the monitor.
Try inserting it into a different main socket that is operating, to see if the power indicator LED lights up.
If you have determined it is the LCD monitor is faulty, then it requires repairing.

My Monitor lost the image suddenly (black screen). When I turn it on, the LED indicate a green light the image appear for 1 sec and disappear. The ON OFF button still green though.... I can conclude...

First place to check will be the DC filter caps in the power supply, it can have circuits failure in the backlight inverter, or bad lamp assemblies (worst case).
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 ACER monitors to get some ideas what to look for:

Monitor will not com on just a blinking green light on the button were you turn on the monitor

If you remove the cable from the computer does the gren light change to Amber? Do you have a input button on the monitor?If you do,press it until it selects the correct input sometimes it may change and select the incorrect input.The last thing you may try ,if you listen carefully you may hear a low humming noise coming from the monitor this is will indicate a faulty power supply.If this is so you will have to replace the monitor
Good Luck.

I have a GEM 17" with power issues!

Sounds like your power supply capacitors are causing the power supply to shut down. Or you have a short in the monitor loading the power supply. You should try a different power supply.

Power on and monitor goes to sleep mode

You need to try it on another PC, alos verify if the VGA cable is good. If nothing change, then you need to open it up, first thing to look for are the capacitors in the power supply. Look for cpas with bulging top/seal, see example of failed monitors here:

Acer AL1715 no lights

We are seeing this same "issue" with this model regularly. If there is no screen and No led/lights, then the power supply has gone out.
It appears on that model there is an external power supply.
Google the model number of the Monitor for replacement parts.

Plug something into the same outlet and verify the outlet is good.

Monitor turns off

Since the green light is going out the monitor's power supply could be the culprit. That popping sound is not good. I would replace the monitor all together.
