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

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 back. 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!!!

    My Acer Aspire 4315 does the same thing. The screen flickers, and then
    it goes completely blank white. If I hit Ctrl + Alt + F11 it comes
    back, but it's only a temporary fix. Also, if it helps at all in
    answering my problem: If I attach an additional monitor to my computer,
    it does not go blank when the laptop screen does.

    I have the same problem with an Extensa 5630 and I dual boot Windows Vista and Ubuntu 8.10 and happens with OSes , it seems more a hardware problem.

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 :-(

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

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

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 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.

At times the screen goes fuzzy and flickering is acer aspire 5732z .13 month old bought new

Two or three possible causes for this.First, the cable that runs between the motherboard and screen may be loose.Second, your "inverter" may be going bad,and third,the video chip on your motherboard may be poorly soldered or poorly seated in the socket.
You'll have to take it to a repair shop to find the exact cause of the problem.

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.

Hi my acer 1710 laptop is flickering and the screen goes blank and comes back on and flickers again you can hardly see the screen what could be wrong thank you stuart

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.

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

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..

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

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.

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