Acer Aspire 5720Z Notebook - Screen flickers, goes blank then comes back on when screen/lid is adjusted

PLEASE HELP!!! My 4 month old Acer Aspire 5720Z Notebook screen started to flicker yesterday and then when blank. When I adjusted the screen/lid slightly it would flicker and after a number of tries I got the screen working. I used it for over an hour and the OS works fine. I did a virus scan etc. and found no other problems. Today the same thing. (Using it right now) What's wrong with it? Is there something loose or is it a major problem??? I have no time to ship it across Canada to Acer for warranty -- this will take weeks!!! PLEASE HELP!!!

    I too have an Acer Aspire 5100 notebook and this problem has been there for soem omnths now and the screen comes on when it is almost closed and then I open the screen gently little by little (trying to fool the screen!!) - to the working position! Or at times I need to open to 180 degrees and then close slowly. But lately even while working the screen flickers and goes blank.



    Please tell me how to go about this and get this sorted out.



    I have always been a Dell owner and I am seriously thinking if I made a grave mistake buying an Acer! Only how I get the help and increase my comfort level, will decide this.

    When I adjust the Display lid to an up right position the display is great. If I move the disply to other positions it goes Blank or Black?
    I did open the base of my laptop and unplugged and reconnected the video cable at the motherboard but problem stayed the same.

    Has anyone fixed this problem?

In most cases like that,where we have screen flickering,first look at the graphics card maybe the signal flex from the back of the screen is well fixed on the motherboard.then if it is well fixed on the board you will need to look at the signal board at the back of the screen maybe it is well fixed if it is not well fixed then fix it properly to solve ur problem then if the problem still persist then u will need to disable the VGA in device manager.to get to device manager u will need to open my computer and after that, u can right-click on it and then click on propertise then click on hardware and then click on device manager where u can disable the VGA.

It is most likely the connector between the screen and the motherboard that is loose/failing. I would check that first, before taking it in for repairs..

    I have am acer aspire 5920g which the screen has been flickering on for some time now, pc world quoted me £225 to put right, so i decided to go it alone, i removed the front panel around the screen, unscrewed the back panel so i could get to the wire running from the motherboard to the screen, this is situated near the top, I unplugged it and plugged it back in and all is well now, it is taped to the back of your screen. This only took 20 mins to complete. better than paying 225 for that little process.

If you HAVE any experience with computer hardware you can open it and check the data and power cables that connect to motherboard that they have not come loose or damaged and thus short circuiting your lcd, but you must be aware that unless you have extensive experience you will probably be unable to open your machine in such a way that you do not forfeit your warranty. but the problem is definitely with the lcd connection to the mainboard. If you arent sure send it to Acer to be safe. thanks

It sounds like a loose connection or a snapped dry solder joint leading to the backlight. On notebooks and LCD monitors, the screen consists of a florescent panel behind the screen which shines a light similar to a florescent tube through the screen. From your description, it would appear that something is becoming disconnected there.

A local specialist in flatscreen repairs should be able to fix it if it's nothing too major. Try and find one who has a certification to work with Acer to avoid voiding the warranty. If you live in Ontario, where I live, I can do a search to see if I can locate one (please either use the ask button to contact me directly or leave a comment on this ticket) but I have no details of potential repair locations outside Ontario.

I have the same problem. It happened to me about half a year ago and reinstalling the OS solved it. So it's by no chance a hardware problem. I have a Acer TravelMate 6291. It must be some kind of a software problem, but don't know which one :-(

MY acer screen flickers on and off and then when i adjust the screen comes back on but now just keeps flickering. please tell me what the problem is


The problem seems to be related with the inverter wire of your laptop. It doesn't properly connect the mainboard with the inverter-which is on the screen.

It is likely that the backlight for your screen is faulty or needs replacing. This is not a job you can usually tackle yourself, you will need to take it to a dealer to have the unit repaired.

How to solve Flickering problem of LCD


I have an Acer 5920G that's only 3 months old and it's screen started flickering. Updating or rolling back the graphics card driver made no difference. I then updated the Chipset driver from the Acer website. It hasn't flickered since!
The graphics info has to pass through the chipset so I assume the driver wasn't up to the job.

ACER 4315 flickering screen (very bad)


  1. First since it is only 3 months old. Bring it back to where you purchase it so that you can avail of the warranty.
  2. If for any reason you cant do that then try the following
  • Turn off your laptop
  • remove the LCD bezel by removing the rubber and screws
  • try to reinsert the cable that attaches the monitor to the INVERTER. The inverter is the one lighting up the screen. Usually this is located at the bottom of the screen
  • if this doesnt work then try to remove the LCD panel and reinsert the flex cable located at the back and see what happens
NOTE: make sure when you remove cable and re inserting them in, your laptop should not be attached to ac or battery.

i hope i was able to help

That would be my guess. Since it is still under warranty, take it back and let them mess with it.
