Question about Acer AL2021M (Silver) 20" LCD Monitor

2 Answers

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

    thanks for that - last time they replaced the "power unit" - this time it looks like exactly the same problem but it's going to cost me too much to either send it back (only 3 month repair warranty!) or to buy a new power unit from them (part number 55L06ve002 at £55.58 including VAT + shipping). And what are the chances of the same thing failing for a third time...)

  • zig zag Jun 19, 2007

    either way it's going to cost me too much - their parts are not cheap and nor is their out-of-warranty repair! their support told me that 3 years is a lot to expect from a monitor - but he's obviously speaking for Acer products - I have an 8-year old Apple TFT monitor here with no faults at all! Anyway - is an inverter the same as a power unit?

  • zig zag Jun 19, 2007

    incidentally - all the lights stay on - in other words - it "thinks" it's on but shows no picture.

  • zig zag Jun 21, 2007

    what really angered me was how many times it was said "unfortunately" with a tinge of schadenfreude.

    time to look at the googlemap!

    thing is - the wretched rig went down on me about a year into the warranty - i had it set aside untill i can deal with a******s again... shouldn't have provaricated, huh? well, better late than never, if you know what i mean. the damage has been done - yeah?

    what would you do? you crazy americans probably would use a pair of durandals...

    i sold it on ebay for around £12 pounds - the guy who bought it said he'd fixed it by replacing two diodes (if i remember correctly) at the cost of 40 pence each... it was too long ago to remember any other details

    this problem appeared on my AL2021 just few time after purchasing, though only after switched on longer than 1 hour. after this time, when monitor becomes hot, if i switch'em off and immediately switch on - it refuses to show picture. then i have to wait few minutes to make monitor cool and switch it on again successfully.

    but today it refuses to switch on even when it is cold. dammit!

    jabez40......al2021 monitor switches on when cold, but dies as soon as it warms up.... the old cathode ray tubes did not have this problem, but the new flat screens are a disaster.. I have seen at least half a dozen at the dump recently... so much for "modern' tech....and the thing is they dont even pretend its not design obsolescent..

    I have an AL2021 with a main circuit board problem - any chance of doing a deal for your spare parts?

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.

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

Monitor goes blank

Try restarting the computer in Safe Mode and then check. In case it flickers in Safe Mode too, then the LCD screen might be damaged and you might need to replace it.

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.

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.
