Yes you are 50% right. The problem with your laptop is either the inverter module or the backlight itself. If you have a little electronic background and have the correct tools, you might be able to repair it. Although, its more practical to replace it with a new one. It is normally located on the lower front part of your LCD panel. If you can remove the front cover of the display, the you will find it on the lower part. It normally have two connectors, one comes from the mainboard, and another (2 wires) goes directly to the backlight.

Screen is not lighting while laptop is running.


Hook a spare monitor to the video output on the back of the laptop, if okay it means the video card is working fine. The problem is a bad inverter board, "located under the LCD display" or the back light is defective behind the screen, "usually means a screen replacement"

Compaq presario cq61 screen went dark but can still see window faintly through the dark sreen.


Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If no luck, try to remove battery and drain the power, then replace battery and turn on.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.

Connect an external monitor to your laptop. If it the image is ok on the external monitor and bad on the laptoop screen it means one of more of backlight/inverter/screen is defective. Have it repaired by a professional.

The laptop turns on, but the screen stays black


If you can shine a light into the screen and faintly make out the images? Then it's probably the inverter/backlight board, not too expensive or difficult to replace in most cases. Let us know.

Gateway laptop- screen went dark but is still on.


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.

Back light or inverter. my screen is black.


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

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.

Dell inspiron 5150 dark screen, faint image in background


If it showed a pinkish tint on the screen before it went out it could be the backlite. If you can see a faint screen when you turn the room lights out it chuld be the inverter. Inverters are cheap ... a used one for around $8 on ebay. Try that first. Make sure that you buy the EXACT model that is presently in your laptop.

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.

If you can see a faint image of the desktop or the machine works with an external monitor, the either the screen inverter or the screen backlight has gone out. Start by checking the screen connections. The connection to the screen, screen to inverter and screen to motherboard. Connections can sometimes work loose. A loose connection generally causes the screen to go out entirely, rare but occasionally it can cause just the backlight to go. If the connections are good, then you will need to take it in to have the screen and inverter tested to find out which it is. If it turns out to be the backlight, you will have to purchase a new screen, screen are considered sealed units and just the backlight can't be changed out.
