Acer 22" X223w LCD Monitor - Page 7 Questions & Answers
What do i clean the screen with?
Cleaning is simple. Vacuum the rear vents to remove any dust that has built up.
For screen and the fascia, -
1. Unplug the monitor from the power supply.
2. Fill a bowl with warm water with some washing up liquid - just as you would to clean dirty dishes. Soak a soft clean cloth in the water (Kitchen cloth - NONE ABRASIVE!! and not a sponge!), and wring the cloth out so that it is damp (not wet!) and gently wash the screen. When finished use kitchen roll to dry off the monitor.
3. Stubborn marks on the LCD, using the same damp cloth, apply a spot of neat washing up liquid to the cloth. Clean as before - DO NOT PRESS on screen. When finished, use kitchen roll as before.
Voila!
Acer X223W power supply
the voltage inverters are the small transformers attached to a small pcb, that is connected to the backlight inverter (cold cathode).
Just in case replacing the capacitors did not work, the second thing to do is to check the backlight inverter. If there is busted light, replace this one too..the last thing to check is the high voltage ballast transformer... if one of these is burnt, it is enough to affect the stability of your supply current. It can also result to a dark portion on your screen or worst , could result to a total black screen..
If you can replace this transformer with the same value, please do so.
If this is a help to you.. please rate this solution...thanks.
Monitor won't come on
Most LCD monitors have common problem due to caps failure in the power supply, that will be the first place to check. Need to verify that you do have 5vdc and 12~18vdc from the power supply output.
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 ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor not working
There are two common reasons for that problem.
1) Your video card on your pc may be having issues.
2) Your monitor is not working properly
Here is a test to isolate the problem to the monitor. Plug it into another pc or laptop VGA or DVI slot and try to power it on again. If it works then you know for sure it's your video card giving trouble. Either gone bad or needs the drivers to be updated/uninstalled and reinstalled.
If it doesn't work then you're looking at some monitor repair or potentially a new one. However since you said you saw the Acer logo, it's a positive sign it's not really your monitor as it would not work all together if it had an issue.
Hope this helps and thanks for using FixYa.com
Picture changed to a blue dominant picture
disconnect the monitor from the system and check if all the pins of the cable are not damaged. if not damaged, then check the device manager for exclamation marks, try and reinstall the drivers
steps to open device manager;
click Start
select Run
type Devmgmt.msc
press Enter
The color on my monitor has a green tint
If your monitor has just started showing an off color tint, try checking the video cable connection on the back of the monitor and the at the video connection on the PC. Make sure the connection is solidly connected and not loose. Wiggle the connection as you watch the monitor to see if the color changes... if so the connection is loose. Try rebooting the computer into safe mode and see if the color issue still shows... if not then you may have a video card issue, overheating can be a culprit
Turns on and off by itself
There can be several causes for this, few of which you can do anything about. However, a few things to try:
1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?
I hope this helps. Joe
Acermointors color is to bright
try to adjust front panel button, for the brightness control + - sign, if not function the problem is the lcd ckt. and need service.
My monitor has gone from a beautiful, sharp screen
Hello Katherine ann, hi, the faded and blurry picture is usually caused by poor LCD panel connections, due to loose contacts and screws. This is usually poor ventilation, or factory defects. Since you mention its only 6 months old, it is still cover for warranty, call your dealer for service.
No Signal
yes start the computer then keep pressed the key F8 untill the display comes then hightlight the option last good known configuration and select the problem will be solved
Power button blinking on and off. Not powering up.
it means your monitor doesn't receive any signal from the system unit, have you check its connection? or RAM, or your video card? try to clean your RAM with a pencil eraser like wise with your Vcard, maybe one of them is busted. Now replace it
