This laptop came for repair because of the LCD screen backlight failure. My customer complained that the laptop LCD screen is black but the laptop works with an external monitor. Here are my steps for troubleshooting this laptop with the backlight failure. First of all, I tested this laptop with an external monitor connected to the VGA port and the external monitor worked absolutely fine.
If the external screen works fine, then most likely there is nothing wrong with the video card. Notebook display assembly diagram. After that I took a closer look at the laptop LCD and noticed that the screen is not completely black.
The laptop screen still works but the image is very very dull, you barely can see it. From my experience I know that this problem can be related the lid close switch, faulty inverter board or bad backlight lamp. I checked them one by one. If you have a similar problem, make sure the lid close witch moves freely. The lid switch is a small button located close to the LCD screen.
This button triggers the hibernation or sleep mode when the screen is closed. If the lid close switch is dirty, it might get stuck inside the laptop case and cut off the power from the inverter board.
The inverter board works as a power supply for the backlight lamp and if there is no power coming to the inverter board, the backlight lamp will not light up either. When I was pressing on the button very fast, I was able to light up the screen but only for a fraction of a second. A pinkish tone usually indicates a problem with the backlight lamp, not the inverter board.
Even though I suspected the backlight failure, I decided to test this laptop with a new inverter board just in case. So, I was right, this problem is not related to the inverter board. Finally, I disconnected the screen backlight lamp connector from the inverter board and connected my test backlight lamp I removed it from another cracked screen.
You can find a new backlight lamp on eBay. Try to find a backlight with the connector already attached to it, so you can plug it into the inverter board. Make sure the connector on the backlight lamp is similar to the connector on your LCD screen. As soon as I turned on the laptop, my backlight lamp lighted up. The laptop screen has a faulty backlight lamp.
This laptop video fails in a little bit different way. The laptop starts with video on the screen but the background has reddish tone, the screen flickers and it makes noticeable buzzing noise coming from the backlight and inverter area.
After a few minutes the backlight turns off by itself and the buzzing noise stops. I removed the screen bezel and connected my test backlight lamp. My test backlight works absolutely fine. So, this laptop needs a new backlight lamp. Dude you rock… I did as instructed.. Thank god but none the less.. Hey Dude! I have problem with my monitor! I press the lid switch and just for a piece of second turns on as you said so probably the switch has no problem.
Sometimes it turns on just for a few seconds so I suppose that there is no problem with thee lamp. So I again uppose that it is a problem with the inverter. Could you tell me how can I open my monitor to change the inverter and an idea on how much this could cost?
Thanks again friend. Very good post…. Hello… I have a dell latitude CPx laptop wtih the problem you described. The screen is still working but I can see only a very dull image. I do not find the lid close switch where you said it was. There is not any button close to the LCD screen, but the power button. Oh, this problem began when the laptop, into its briefcase,fell to the floor and slightly hit its back.
Maybe is anything broken in it, like the backlight lamp or the video cable? I have not opened the laptop. Wojciech, It could be just a loose connection on one of the inverter ends.
Try reseating these connectors, it might help. You cannot tell with part is failing the inverter board or the backlight lamp without testing the laptop with a known good backlight lamp or inverter.
I think you might have a dead backlight bulb because the laptop was dropped. Anyways, try reseating cable connections first. Hi, I think my back light inverter may be faulty.
You can see the image on the laptop but it looks like every other vertical LED is not lit? The question is, can I get a replacement back light or will I have to buy a whole laptop screen? Yours suggestions would be very much appreciated. Eugene, If you still can see the image on the laptop screen then the problem is not related to the inverter board or backlight lamp. When you have a dead inverter or backlight lamp, the whole LCD screen will be dark, not just some vertical lines.
From your description I would assume that you might have a faulty LCD screen. There is a possibility that your problem is related to the video cable. Second, in most cases you cannot upgrade the motherboard. However, once I installed the screen, the same thing happened that the last screen was doing.
The video would show up VERY faintly and the external video would work, but the backlight would not work. I tried switching inverter boards and nothing helped. I think I may have a grounding problem. Does anyone know where it goes? Please Help!
Last year the LCD light began flickering and I could hear a faint high-pitched noise. It eventually went out completely. Now, I can barely barely! I have a desktop at home also, and tried to hook the monitor up to the laptop to no avail.
I went through troubleshooting and cannot figure out why the laptop will not comply with the external monitor. There might be a problem with the video cable. I would try replacing the video cable next. Not sure if you want to go this route and I would do it only as a last resort.
This hight pitched noise and flickering screen could be caused by a faulty inverter board or failing backlight lamp. I would try replacing the inverter board first, you have a better chance to fix this issue. A few days ago I was troubleshooting a Dell Inspiron m with a similar problem. In my case the screen was making noise and it flickered as yours, but when the backlight was on, the white colors had reddish tone.
I connected my test backlight lamp and it stopped flickering and the noise was gone. So in my case it was a faulty backlight lamp. When your screen flickered, did you notice that white background had reddish tone? If it was normal white then most likely you have just a faulty inverter board.
Could be a problem with the motherboard, video card, CPU or memory. I think you should take your laptop to a professional repair shop for diagnostics as you have more then one problem.
Before I order the inverter I would like to have one more question that might help if it is the lamp or the inverted. In the begining, before the screen is totaly black not exactly black but with this shadow , sometimes suddently the light turned on until I switch off the laptop but next time again black.
This hapenned for times and then all black…This indicates if it is inverter problem or backlight lamp? Thank you…. Angelos, It can be inverter or backlight lamp. You cannot tell until you test the laptop with a known good inverter or a known good backlight lamp. You said the screen is black. How black it is? Can you see faint image on the screen? Yes, I can see a little. Especially if it is dark in the room I can see more.
Also I am not hearing any noise from inside. I would try replacing the inverter board first.
