Question about Compaq Presario M2000 Notebook
i have a similar problem with my acer aspire 4736z, it was never dropped or anything. the first time i saw it was while i using live messenger and then i heard a static like from when a mobile phone is nearby. i remember the screen sort of flickered and then suddenly the pink vertical line appeared. sometimes when i open my laptop there's no pink line and then goes back again after sometime. can someone help on how to remove this? i already tried unistalling the display driver its still there.
You may 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 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 the monitor up first then the laptop, 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.
