SOURCE: Dim display ... no backlight

You most likely 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.

SOURCE: verticle stripes on monitor--Toshiba Qosmio

Following factors could be causing this problem and solution as well:

1) Cable Cut: check is to see if the cable between the screen and laptop is pinched or cut. Every laptop has this wire that runs through one of the hinges

2) If this problem temporary i mean for some seconds then it could be a short signal cut problem to screen which causes screen distortion

3) Connect an external monitor and restart the laptop. If you see the same strip on the external video, then that is the motherboard or the video card problem in case you have a video card on your laptop apart from integrated graphics chip

Hi i have problem with toshiba qosmio g25-av513 when i power on its show clear QOSMIO monogram and then start show saverl difrent colurs lines i try with external monitor show same .pls help me to fix this...


You can try downloading the most recent video drivers from the nvidia web site and installing them.

Other than that you would probably need to contact Toshiba tech support. Based on the information you provided it sounds like your video card is having a hardware issue. It's the reason you see the same lines on both monitors.
