My PC's screen is flickering. Solved

Question

Hello everyone,

I hope I'm in the right forum...

Here's my problem: my computer screen keeps "jumping", it has interference like static, as if my laptop were right next to me and about to ring... It does this at irregular intervals, more or less strong, whether it's on or off.

My PC is an ACER 5920 (only a month old). I have a Mobile Intel 965 Express Chipset Family card. And I got rid of Vista to install XP instead (I don't know if that has anything to do with it but just in case...).

I've already uninstalled the drivers, done a virus scan, and then reinstalled the drivers without any results.

Finally, Acer's hotline advised me to completely reformat my PC... I must admit that if I could avoid that, it would be great!!

So, if anyone has any ideas, it would be really awesome!

Thanks in advance!

Hi everyone

I found a solution on YouTube that's better than customer service, since November 12, 2009:

You need to take apart the screen's plastic and put it back together. Miracle! No more flickering,
I didn't do anything special, didn't touch the wires or anything, just took apart and reassembled the casing
my screen was also flickering before, especially when there was a lot of black in the background.

Pay attention during the video, you don't need to understand English.

Good luck.

Do you have any photos???   Otherwise, it might be the graphics card that’s acting up  Are those artifacts??

Pacos06 · Answer

1 Define whether it's the monitor or your PC! Borrow a monitor, or go to a friend's who has a PC with your monitor
2 See if a power line filter could solve the problem
3 Check if you have any appliances that are messing you up... unplug everything and test only your PC

Lillykat · Answer

Thank you for your responses!

@swatclem: I tried to take screenshots but the noise doesn't show up on the jpg...
And sorry but... what are artifacts?

@Pacos06: For the monitor, I'm not sure how to do that, we're all on laptops... I'll try to find that out anyway.
As for my appliances, I only have the TV on standby. Even turned off, the noise appears...

swatclem · Answer

An artifact is a point or a line of breakage on your screen, often due to poor stability of the graphics card.

To check if you have artifacts:

download ATI TOOL
run the artifact scan

let it run
if it beeps, it means you are not stable
if you see yellow points appearing during the test, then the frequencies are poorly adjusted.

Hello, I am encountering the same problem with an Acer Aspire 5920G that is a few months old. Have you been able to resolve this issue? Thank you Best regards Marc

Lillykat · Answer

Hello Marc,

Well, after reformatting my computer, the problem persisted...
So I resigned myself to sending it in for repair; apparently, it's an issue with the LCD cable.

A little info about the repair service... I sent it on November 27 with a return time of 2 to 3 weeks.
Three weeks later, still nothing, so I called.
"Yes, we received your computer on the 27th, we've been waiting for the part since the 28th..."

With a bit of luck, they might have ordered several, and you won’t have to wait as long! :)

Lillykat · Answer

For those experiencing the same issue, it was indeed the LCD cable that was acting up. I got my PC back (almost a month and a half later - sic!!) and everything is going well (for now...)!

Lillykat · Answer

It's more than a temporary solution...

That's what I was doing at first too, but using your phone halfway closed or fully open is better!

And in my case, towards the end it was useless, the glitches persisted. The only solution was to change the LCD cable!

We must have gotten a bad batch!!! :)

Nico · Answer

Here, I had the same problem a few months ago
Of course, when I sent it to Acer, they didn't find anything and the image wasn't flickering... (it must not have flickered at the right time)
They told me they had unplugged and replugged the display cables...
I received it back 4 weeks later and it worked fine for 2 weeks and then the problems came back
Today I'm getting in touch with Acer... we'll see.. I'll tell them it's probably the LCD cable..
I recorded the problem and left the video on the Windows desktop...
We'll see, hoping the problem doesn't come back for you

Nico

TREP · Answer

Even Acer 5920G, after four months, the same screen flickering issue!

Thank you for bringing the solution here! It’s a problem with the LCD CABLE, not as bad as a graphics card issue, I initially thought it was a tropical overheating...

In the meantime, I changed the screen tilt axis and for now, it’s better...

Bought in Quebec, I’m in Guadeloupe for a few more months.
Who should I contact for service?
Can someone please guide me to a webpage (or a specific phone number)?

Thanks, everyone! ;)

truite38 · Answer

Hello everyone, same Acer 5920G PC so obviously the same problem.
But it's even worse for me, I actually sent the PC back around Christmas 2008 (I bought the PC in September 2008) via Fnac's customer service, it came back to me 3 weeks later with, like you, a problem resolved due to the LCD cable (they specify that a refurbishment was carried out) but since about 15 days to a month ago, the same issue has reappeared, so I’m really annoyed.
What should I do? Does anyone know how to do the fix themselves and explain it? Or should I send it back to customer service once again since it's still under warranty???
Thanks for your advice or help.

Lillykat · Answer

If I were you, I would send the PC in for repair.
As inconvenient as it may be, it's the only solution. I've also gone through the phase of "I adjust the screen whenever it flickers," but that's really not a solution.

And most likely, the problem isn't even inherent to ACER and could come from their supplier who sent defective LCD cables.

Take advantage of the warranty and send it back! :)

deniss · Answer

Yo,

THE SAME, Acer 5920g is really not serious, if it's a generic problem they could have issued a slight statement.
I bought my pc a few months ago, at first I also thought it was the graphics card, but after some tests and research on forums, it’s definitely the hardware that is the issue.
I noticed it jumps a lot more in the presence of black (who knows why ;))

TREP:
Grouping: If Acer can't solve the problem, all owners of an Acer 5920G should band together to pressure the company. Would anyone have the time to form this group via a blog for example?

+1 for TREP

I confirm that by changing the angle axis it works perfectly (but for how long...)

colline62 · Answer

Hello
I also have the same problem with my Acer Aspire 5920G purchased in July 2008.
The screen started flickering a few months ago. At first, it was slight, but for the past few weeks, it has been getting worse.
So, it's going to the repair service, but is it useful if they replace it with the same cables...?

Rangia · Answer

Hi,

Well, I am also a victim of this problem. I've had my PC, the Acer 5920, since September 2008 and about 3 months after that damn bug appeared. At first, I was scared, but I found out that the problem could be solved by lowering the screen. However, for the past few days, the problem has worsened; I have the screen almost all the way open, if I may say it’s not practical to surf on it. -_-
Thanks to you, or at least it seems that way, the problem doesn't seem too serious since it's a LCD card issue, so tomorrow I'm going to take my PC to my vendor. It better be fixed and not appear again! :(

Rangia · Answer

* LCD cable  Sorry. ><

Deniss · Answer

Well, I called Acer's customer service, I really thought they had documented this issue with the 5920g. It seems to me to be a flaw across the entire range; it's impossible they wouldn't be aware of it. Yet, the technician checked the issues related to this range but found nothing. I think Acer is being disingenuous and trying to hide the problem.
In any case, I'm sending it as soon as possible. They say it should be resolved within 15 days.
Kiss

Rangia · Answer

Excuse me for being such a pain, but what is the number to contact Acer customer service? I live in France.

colline62 · Answer

Good evening Rangia I called the number 09 69 32 03 42. I found it on the ACER website. It is free when calling with Free. I don't know about the other ISPs  Otherwise, there is 0825 00 22 37 (€0.15 including VAT per minute)

Rangia · Answer

Thank you, I will call tomorrow and if they are closed it will be for Monday.  Another question, I bought my Acer from a seller, he ordered it online and I just had to wait for him to receive it at his shop to go pick it up. The problem is that I don't have a warranty, he didn't give me one actually. So it's not going to work if I want to send my PC to them...?

Rangia · Answer

Damn, it's getting worse and worse, even changing the screen's angle, it's almost fully unfolded, I don't know what to do, I don't have a warranty even though I bought it less than a year ago, my seller isn't open until Monday! :'( :'(

Rangia · Answer

I didn't see your message TREP but even when I move the screen very slowly it still glitches. Right now, I've got the screen almost all the way down, if it messes up with the screen down all the way then I'm in trouble... But anyway, I went to see my seller (who's back from vacation >

Rangia · Answer

I hope luck will smile on me too. xD  I’ll come back to give updates at the next one!

Toms56 · Answer

Good evening, I had a screen flickering issue too, and I accidentally solved it by overclocking the graphics card (with RivaTuner), no more problems since. I must say it’s much more relaxing... ;)

judbox · Answer

Good evening,  I have the same screen flickering problem with my Acer Aspire 5920.  I may seem silly, but since it's under warranty, should I send it to Dary for service or call Acer to send it directly (is there a cost)?  Thank you

Rangia · Answer

Hi, so here's my screen problem is solved. Last Tuesday, as I was passing in front of the computer store, my seller had received my PC. It was sent on June 22-23 and I picked it up on July 2nd. A bit long considering the 5 days from colline62. :/  It was indeed an LCD cable issue, a failure of the part, I received a report confirming this.  I hope it won't take 2 months and then boom! trouble again...  Goodbye!

JEHRA · Answer

Hello everyone,  From everything I've read, I must have the same problem but perhaps less pronounced. Indeed, my screen "jumps" about every 5 minutes (that's an average; it can happen 10 times in 2 minutes or just once in two hours), but if I move it a bit quickly, it works again for an unpredictable amount of time. The problem is that unlike you, I own an Aspire 7730Z and not a 5920g. Do you think it's still the same issue, meaning the LCD cable, which would suggest that Acer has quite a lot of problems with this cable across different models, or could it be of a different origin? And do you also think that I should send it to customer service, which I really don't want to do, or that these problems won't worsen (since I can still manage with it)? Thanks in advance for your responses as I've had this computer since Christmas and it's been doing this since April, so it's really frustrating...

JEHRA · Answer

Yes, I experience this systematically at startup until it asks for my password. However, once it’s on, it’s very random. Do you think it could be due to the heat? I live in Var (so it’s hot^^), my computer is in my bedroom on the top floor just under the tiles and there is no air conditioning. So I've noticed that when it’s over 30°C in the room, it happens much more often and regularly than when it’s (only) 25°C like today.Do you think it’s just a coincidence or is there a connection between these two factors?

JEHRA · Answer

I think it’s still under warranty, but I really don’t want to send it to customer service when I see that in some cases it takes more than a month to come back... Let’s just say I’m very "attached" to my computer and I can manage without it for a week but not a month. Anyway, I’ll decide at that moment if the problem gets worse. In any case, thank you for your clear and quick responses.  Have a nice day.

Maykrill · Answer

So to summarize the situation with the information from the forum:  The Aspire 5920g by ACER has been affected by the same display issue that jumps or flickers since at least JULY 2008 (my PC is one of them, I bought it in September 2008) and it's still happening now. However, Acer has not recorded any functional problems with this series since 2008, despite the increasing calls and letters requesting repairs for almost every Aspire 5920g regarding the LCD cable. I would even go so far as to say that they seem to have changed the cable on my machine, but despite this operation, just two months after getting it back from customer service (unlike some testimonies, my computer took over a month to return from ACER against the maximum two weeks announced), my screen just started acting up again about 5 hours ago, even worse than before the service (that's saying something). The best part is that my warranty expired just a week ago (isn't that nice?).  Acer claims not to have recorded any problems with the range. Aren't they just mocking us, excuse my language? Is it not possible to contact a consumer association to defend our rights against such a scam? Because apparently hundreds of people seem to be affected by this malfunction, and the company doesn't seem bothered by the numerous testimonies it receives while pretending not to know.   PS: Once my current computer has given up the ghost, I will never buy or recommend, and I will even dissuade anyone I know from buying any product from the ACER brand, which ultimately only has price as a selling point.

I have the same problem with my computer which is barely 1 year old. I just saw tonight that the screen was "flickering" in a worrying way, which it didn't do this afternoon! It's an HP Pavilion dv5 1155ef... What can I do? The icon representing the battery indicates that it's completely dead even though I'm plugged in, but when I click on it, it obviously shows that I'm at 100%! It hasn't happened since I typed this cry for help... but come on, it's brand new for crying out loud! I restarted it and it happened again almost instantly  Help, I'm awful with computers and all this freaks me out I've never dropped it or anything I installed Sims 3 on it (which is frankly not great, so if I need to delete it, no problem!) so it's known to eat memory, but still, my computer isn't an antique (well in my opinion, I know that after 3 months a computer is no longer "good," but no one changes theirs every three months!)  Thanks in advance

Thank you Zrezo My husband just took apart the screen of my laptop. He didn't touch anything. He put it back together and there's no more flickering images. Yet it was getting worse and it was really starting to annoy me. And now even when I move the screen, I have no problems at all  A big thank you for your intervention

Adrien · Answer

Hello! I also own this famous 5920g and I've just started experiencing the first symptoms described above. The thing is, these symptoms appeared right after I installed Windows 7. Do you think it's a coincidence or could there be an incompatibility between the laptop and Windows 7?

kuicui · Answer

Hello everyone... I own an ACER 5920 G Well, maybe I can provide some answers to some and perhaps solutions for others... I also experienced horizontal buzzing problems, like some sort of interference that appears very briefly on my screen...  Initially, there were no issues... however, each time I updated the drivers for my graphics card, the buzzing returned.. Recently, I installed Windows 7 and once again, the buzzing came back because Windows automatically updated the drivers for my graphics card...  I managed to overcome the problem by reinstalling the original drivers, that is to say, by installing version 7.15.11.7590, which I downloaded from the ACER download platform...  You can find the page by clicking on the following link  http://www.acer.fr/acer/service.do?LanguageISOCtxParam=fr&miu10einu24.current.attN2B2F2EEF=291&sp=page15e&ctx2.c2att1=8&miu10ekcond13.attN2B2F2EEF=291&CountryISOCtxParam=FR&ctx1g.c2att92=25&ctx1.att21k=1&CRC=1143633635  Search for the Acer 5920G by selecting Laptop then Aspire  Download the VGA driver for Nvidia cards to the previously mentioned version.. Don't forget to uninstall the old one before reinstalling the new one...  For me, it has always worked with this version on both Vista and Windows 7 There you go Good luck PS, I didn't need to open my screen's cover to fiddle with any wires...

Ursula · Answer

Hello,
I've been experiencing exactly the same problem as you for some time now. My PC (Acer 77302) is 10 months old and this had never happened before.
I informed Acer, and they sent me a message with three solutions that, for my part, are very complicated. I prefer not to touch the configuration, or anything else for that matter.
I will talk to my retailer and wait for what they suggest.
If you have any information, please pass it on to me.
Best regards

Nanastyl · Answer

Well, I would like to announce that I have an ACER 7730 ZG and I have the same problem, and on top of that, my "i" key is loose! I've had it for a year and a half! So if anyone has found a solution for this "jumping" screen issue, please don't hesitate, and let me know how to reattach my "i" key! Thank you in advance!

Merwane · Answer

For the key, it happened to me once with the "S"; it took me no more than 5 minutes to put it back; you just need to be careful and put it back in place..

As for the jumping screen; if I don't get a response, I'm going to lose it knowing my warranty has expired.. :@

Hello, I have an Acer 7730Z that is a year old and I'm also experiencing screen flickering issues, especially in the morning. I just opened it more than half an hour ago and I'm not encountering any problems. I also found that having the screen fully opened resolves the issues, but that's not a solution. Thank you for your help.

Ursula · Answer

Hello, I'm still having my screen flickering issue as soon as I open Acer to watch videos. Does anyone have a solution? Thank you

senysensy · Answer

The problem is very simple, I have a problem which is a wrong contact for those who don't know it on Mongalé Street in the 12th arrondissement of Paris metro Reuilly-Diderot, there are computer repair shops that can fix it for 30 to 70 euros that's the store, I hope this helps you.

meli18 · Answer

Good evening, I have a portable computer Aspire 7730z and I have the same problem as you. My screen keeps flickering more and more, and I have to use it almost closed to prevent it from flickering. The only issue is that I have not been under warranty for a while, so I wanted to know if it is possible to fix the problem myself... Thank you in advance for your response.

Merwane · Answer

I'm disgusted; I did the operation it worked well for 24 hours.. And now, it's starting to come back. Acer: it's over.

meli18 · Answer

Have you checked if your cable is damaged? Mine was cut, and since I put electrical tape on it, I haven't had any problems, and when I close it, it doesn't trip again.

vince · Answer

I found a little trick when I opened the case; you can see the LCD cable. What I did was press on it in several places with my finger to figure out where the problem was coming from. At one point, the screen became stable again. I then wedged a piece of paper to press on the cable between the screen and the case. For two months now, I haven't had any problems; everything is working correctly.

My PC's screen is flickering.
