No backlight


A) Replacement LCD screen backlight could be bad.
Happens. Sometimes you get a bad part. (Bad LCD screen assembly, in this case)

LCD screen may not be the correct one.

A screen Inverter, and an LCD screen; are a MATCHED unit.

B) Screen Inverter:
May be bad, or the Wrong one

C) You may not have the screen Inverter, connected correctly to the Backlight.
Connections aren't tight.

D) The Display Cable TO LCD screen connection may not be tight, or correctly connected.

I know the display shows graphics, but a poor connection of Display Cable to LCD screen, can make the Backlight dim out.

I'm betting it is a poor connection, or the wrong screen Inverter, or wrong LCD screen.

My screen on my laptop just went all black with a very faint image. what is wrong there, how do i fix it, and what made this happen?


A) What is wrong?;
Your Backlight has gone bad, or the Inverter.

B) How do I fix it?
Replace the Backlight bulb, or the Inverter

C) Backlight bulb's, and Inverters, like everything have a 'lifespan'
This one is at the end of it's. (Stating the Backlight or the Inverter

From here all I can give you is Generic information, since I do not have the laptop manufacturer name, and Model Number. This is on the bottom of the laptop.

1) An LCD screen cannot produce enough light by itself. A Backlight bulb, (Or more than one), is used to emit enough light.

2) A laptop cannot produce enough power to power the LCD screen, and is also used for power to the Backlight.

I'll have to discuss the way the Display Assembly is put together, and name parts in order to explain the following of how to repair. Again, generic information.

1a) The plastic top of the laptop is the Top Cover. There are different names used by different manufacturers.

1b) Looking at the LCD screen with the laptop open, there is a plastic frame that goes around the edges of the LCD screen, and is in Front.
This is the Display Bezel

1c) The LCD screen is behind the Display Bezel. The LCD screen is a composite of layers. The outside layer that faces you is a protective screen.
Around these layers composing the LCD screen, is a metal frame.
One side, (Or both sides) of the metal frame is removed to access the Backlight bulb.

1d) The Backlight bulb is a CCFL.
Cold Cathode Fluorescent Lamp.
Very similar to the fluorescent lamps, (Bulbs) uses in residential, and commercial applications, but on a MUCH smaller scale.

Now to show you generic laptop info on replacing the Backlight bulb for them.

A) http://www.insidemylaptop.com/category/backlight/

B) http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

If I had the laptop manufacturer name, and Model Number, I could try to give you a link to the Service Manual for the laptop. (Free. Usually from the laptop manufacturer)
This way you would have Exact info on how to disassemble your laptop's Display Assembly.

Toshiba P10 laptop screen no longer works.


It's not the inverter but the biotin backlight bulb that lights the display from underneath. The screen needs to be replaced unless you want to try and rebuild it and replace the backlight bulb. New screens from EBay should not be more than 70-100 bucks. If you want to try and replace the backlight bulb, the link is below for the procedure.....

Satellite M105 S322 Display very Dim. The PC works fine with external monitor but the LCD display is dim and cannot see anything on the screen


You have lost your backlight which is a thin long bulb built into the bottom of the screen itself. You have the option of getting the backlight by itself and rebuilding the screen or buying a new screen assembly and changing that out. Below is the service guide to change the screen.

Camera turns on fine. I could view picture and all. Just that when I switch to camera mode a video screen is blacked out. Why is that?


Your have a "Display" button that toggles thru different display modes .. one of the modes turns off the LCD backlight .. that useful if you are in bright light and dont need the backlight .. you have a very nice "transflective" display that works great in bright light without the backlight ... you can get more shots with the backlight turned off on each battery charge .(about 25% more) .

so each time you operate the display mode button you will get a different display .. one shows a hystogram .. one turns off the backlight and one puts the camera in a normal mode ..

if everything is working right then even with the backlight turned off you should be able to go outside or any brightly lighted area and see the picture on the screen ..

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.
