Toshiba Laptop - Dim Screen

Hello All.
I have a Toshiba Laptop, and the screen went Dim, so the only way to view it is to hook it up to a television with the S-Video Cable.
Can someone please give me a list of possible problems and the amounts that it would cost?

Re: Toshiba Laptop - Dim Screen

Hey, sounds like the back lights in the laptop are faulty, if it is backlights you should be able to see the whole picture but will be hard to see and dull.

Heres one website that sells them, aint sure if its the cheapest place, last time i think i was about £80 for them. which is alot of money but depends on the laptop make etc.

Have a nice Christmas when it comes,,

Hello !

Since an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.

Toshiba screen is blank ans light on under F10 key.

Is the screen completely blank, or just dim? If it is dim, then most likely your lcd power inverter is bad, and needs to be replaced, which is the cheapest part to replace. If it is completely blank then you should try to hook up an external monitor to the laptop, and don't get any video, then most likely there is an issue with your motherboard or video card. The external monitor method sometimes needs you to press a combination of the Fn key and another F key in order to switch from your laptop lcd to an external monitor.

My Toshiba Satellite A105 screen comes on for a little bit, flickers and then shuts off. However I can faintly see the screen, and the laptop works fine when hooked up to the external monitor. Wondering...

If you can still view screen if you view it in an angle or spot a flashlight on screen. Then, definitely it is a problem on backlighting, might be loose connection, inverter giving up or cfl giving up.

Hope this helps

You can brighten or dim the LCD screen by pressing the Fn key plus another key with the a sun symbol eg the UP & DOWN arrow keys or one of the F3 to F12 keys - it varies depends upon the model of the laptop.
If you cannot vary the brightness of the LCD screen the you have a faulty backlight.

Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.

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.

First test is hold a flashlight at an angle to the screen to see if there is a faint image. If you can see the image with the light then the problem is with the laptop's display, either the backlight went out or the inverter is bad.

Second test is to hook an external monitor by VGA cable. Image should be complete and in full color if the onboard video card is functioning.

Please post comment with results for more direction.
