Question about Acer X221WSD Monitor

1 Answer

Blank screen my acer x221w started making a high-pitched noise. I power-cycled the computer and monitor. When the monitor came back on, the screen remains black. If I toggle the monitor power switch, the screen comes on for a few second, then goes blank. During that brief time, I can see that windows xp is functioning, mouse works, etc.

Possible that the HV inverter or the CFL tubes are going bad / defective. I suggest to bring the unit to an authorized Acer service center for proper check-up / test & fix the problem. regards

Acer aspire x1700 black screen, makes high pitched noise, doesn't respond


You may have damaged or dislodge a component.
I suggest you remove the cover and reseat the RAM modules and all the cards in the expansion slot (unscrew them pull them out of the expansion slots and insert them back then secure them with the screws.
If it still does not boot up then you need to take the computer to a computer repair shop.

Hello,

Yes, The inverter is the problem on your monitor. We have a step by step guide to dis-assemble and repair your monitor posted on our web site at:
www.ccl-la.com/monitor_repair.htm Your model is the same as the westinghouse L1875NW. We have a parts kit for $12.00 if you need it, it can be purchased on the guide page. If you don't want to do the repair yourself we can do it for $35 + shipping. This is a common problem with that series of monitors but the repair will get you back going.

I hope this helps, if so please rate our solution.

Acer al1916b high pitched noise when on standby.


Sounds like you could have an open ground? Also might check the wiring to see if you have a faulty connection in VGA cable or power supply cable

Blank ACer X221W Monitor


Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it went dim and blank, you have to check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

ACER AL1716 acting up BAD!


Be more specific. I guess your monitor has inbuilt speakers which are making noise. If yes do come back for a solution.
