That really depends on when it flickers, does it flicker when you move the display open or closed or when you press some part of the laptop?

If it happens when you press a part of the laptop, the display cable could be loose, thats unlikely.

I recently had a similiar problem with a toshiba laptop, the screen would flicker when pressed on the bottom left side of the laptop.

I checked the wires and they where fine, in the end I seem to have fixed the issue by pressing on the top cover where the issue happens and at the same time from the bottom from the same spot, what I did on that laptop, there was a cover that I could remove so I could press directly on the mainboard, pressing directly on the mainboard with my fingers and at the same time pressing down from the top seem to have fixed the problem on that laptop.

Acer Laptop Screen Flickers & Jumps


Hello,



Please connect the laptop to an external monitor. If no flickering on monitor screen, from my previous experience, this is more likely loose connection of video cable connected to the LCD. So talk to Acer support again and require the replacement of LCD.

I had the same issue I researched and saw if you had a flicker to remove these subkeys in regedit
In REGEDIT navigate to HKEY_CURRENT_USER\Control Panel\Desktop\
WaitToKillAppTimeout value.

HungAppTimeout value


Also apply this for all users
In REGEDIT go to to ‘HKEY_USERS\.DEFAULT\Control
Panel\Desktop
WaitToKillAppTimeout value.
HungAppTimeout value.

ACER EXTENSA 4620-4605 model screen problem


If you wiggle the screen and it comes back, then it is not your Video card. Probably just a loose connection with your LCD cable to the LCD screen. Although you may also need a new screen/cable.

The weird thing is that it "fades" out... which would indicate a bad screen to me.. but securing the cable is alot cheaper to try first.

Completely rule out your graphics card by connecting your laptop to an external monitor... if it works fine for a long period of time then your card is fine.

Good Luck.

Screen will not light up


You most likely have a defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
