Question about Acer AL2021M (Silver) 20" LCD Monitor

Monitor flickers and then goes blank

I had a problem with my al2021 20" monitor - after 2 years from manufacture date (i'd bought it a bit later), it started flickering and then wouldn't show any picture at all. Just before the end of their 3 year warranty I sent it back - DHL arrived the next day and several months later they'd replaced the power unit and it worked - but now it's happening again - exactly the same problem - first the flickering and now no picture at all! I called them again only to discover that their repair warranty is only 3 months... Unfortunately for me, the monitor stopped working 5 months after they'd repaired it... they told me it would be cheaper to buy a new one! so i will - but never another Acer product - steer clear of Acer! their technical support put the phone down on me twice - and i wasn't swearing or ranting - just made my despair and dissatisfaction clear to them in a polite way! They didn't volunteer their names and refused to pass me on to any kind of management, then wouldn't give me their surnames. I can't really blame the technical support people for working for such a dodgy setup that sells unreliable products! But I will do my best to warn everyone against ever buying Acer! 3 months seems rather a short time for a repair warranty - I don't suppose there is anything more I can do... Do spread the word if you have any sympathy with me - I paid good money and expected better reliability - especially after they'd fixed it once already!" Very Dissatisfied Ziggy Folkmanis

Re: monitor flickers and then goes blank

I had exactly this problem.
I fixed my AL2021 by replacing the output caps on the power board. $4 repair. Pull the thing apart (I posted somewhere on fixya how to do it, but it's simple) and replace the 1000uF, 680uF and 470uF caps on the end of the power board.

Re: monitor flickers and then goes blank

Most likely you have a bad inverter, or bad connections on the inverter board. Send the monitor back to them and tell them to repair it right. Good Luck

I bought my emprex monitor 3 yrs back. For all these years it had worked its best. But now, when the computer is powered on, the screen flickers by producing small poping sound and goes black...please...

Yes it can be repaired usually just easier to by a new one. it sounds to me like it is a power supply for the monitor. The only hard thing would be getting the power supply for the monitor. Your can try contacting the manufacturer for it :) hop this helps

Change the screen resolution. The video card or video display may not be compatible to the supported video setting of the monitor. Try changing the video resolution to a lower setting such as 1024x768 and bit depth to 32 bit.

Samsung 204B random blank screen

I too have a dual monitor Samsung SyncMaster 204 setup. My monitors started flickering, then a week later had turn on problems like your describe. I found a fix on this fixya website and followed the fairly techie suggestion. It worked. I wrote up a .pdf set of instructions so others might also benefit. Hope this helps. Doug

LG old but brand new blank screen green light making a tik,tik,tik sound.

Nothing you can really do yourself with that. I would call manufacture and get solutions from them. When it comes to monitors, unless your skilled in repairing them you will only do more damage to them. If you really feel like jumping into it and have nothing to lose you should be able to find a service manual on this monitor here and rip it apart to find the piece to replace.

My Monitor flickers when computer starts

If "messing" around with the CRT connection on the back of the monitor causes it to work then I suspect there is some physical damage to. Specifically what connection/connector did you mess with? I can give you more advice if you give me more to go on.
