Sometimes no display on screen of acer 3680 when starts

Hi I have an Acer Aspire 3680 and since few months when i start my laptop there is no display on my monitor. i can hear the sound of fan it is running, all the light from cd rom and indicator blicks but the screen is very dark . i can feel there is some text running and laptop is starting but no display on screen (visible very thin- i tried alt+up arrow but do not work )then i again shutdown the laptop from start button directly and starts repeatedly . when i repeat this process many many times then sometimes it works sometimes not.

This problem happens frequently in 2 or 3 weeks so these days i don't fold the screen and let it as open. This helps me a few but problem is not totally solved yet. In the meantime i also format this laptop thinking that may be it helps me but i have not get any differences. when i have this problem and i directly shutdown the laptop i am feeling that it will hurt my PC more but i have no other alternative and i am very worried about this problem . so i am expecting your suggestion.

If you hear the hard drive spinning and you think Windows is working but you can't see an image then :-
You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

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 or appear black.
  • 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.

You might want to give this a try. Start Menu - Choose Control Panel. Then choose Power Options. You should have several options depending on performance or saving power. Choose Change Plan Settings, and adjust the display brightness to suit your needs.

Hope this helps.

Screen Flickering on Acer 3680-2682


Ok we must remember when we setup any device on our PC, one of the many non PnP devices is and LCD Monitor, your PC should always be shutdown before installing a new Monitor. If you did not do this you could have damaged the I/O port on your PC. Not a definite, but possible! When you plug up a monitor or any serial cable while the PC is still on, it is of a low voltage which can casue some issues for you! Sounds like this one is yours!
