I have stepped on my Dell Inspiron N4010 laptop recently by accident and now it has many long and short cracks all over the screen and i understand this can be fixed by just replacing the screen?

But with cracks, i also have green and black lines around my screen….. will these black and green lines go away as well if i replace the screen???? i would really not like to replace my entire laptop.. screen itself coasts so much… so please help me!!!

P.S. … do u happen to know how i can check what kind of screen i have?

I think you’ll have to replace the screen. All these black and green lines should go away when you have a new screen installed.

Take a look at the following YouTube video explaining how to replace cracked screen on a Dell Inspiron N4010 laptop.

You can search for a new replacement screen using the screen model number which is printed on the screen sticker. You’ll have to remove the screen, find the sticker and located the model number. After that just google the screen model number. Also, new Dell Inspiron N4010 screen available on eBay here.

Have a 2 year old Dell M1330 laptop. Yesterday the screen went black then came back on then black again and after that the screen turned teal and went nuts….. like it almost looked like if you went to a tv channel that wasn’t there. Then I shut it off because nothing would work and tried turning it on and it came to a white screen and after ten mins could see a screen that said something but the image was super blurry and I could not read it, only see an outline of the box on the screen. Now it came back on, but it has happened twice. Any ideas???? Let me know what you think! Thanks!!!!!

Possible video card failure. This Dell laptop might have a problem with the graphics card failure.

Take a look if your Dell M1330 laptop listed in the affected models.

My granddaughter tripped over my power cord on my Compaq laptop now my screen shuts down like after I start it the screen goes black. If I touch the display switch I can not see whats on the screen. If I angle it right I Can see my Windows screen. Think I should get another switch and replace it? Or any one got any other idea what to do?

I doubt your problem is related to the display switch.

From your description it sounds like the laptop has either failed inverter board or failed backlight lamp inside the screen.

If the laptop was dropped, probably the backlight lamp was damaged. It means you’ll have to replace the screen because the backlight lamp mounted inside the screen.

If I would have to fix the laptop, I would probably go though the following steps:
1. Test the laptop with an external monitor, just to make sure that external video still works fine. This will confirm that your video card/motherboard operate properly.
2. Reseat video cable connectors on the motherboard, LCD screen and inverter board, just to make sure it’s not just loose connection.
3. Replace the LCD screen and if it doesn’t help, replace the inverter board.

I have a Sony Vaio VGN-FZ series laptop. The video stopped working but it didn’t fail in one day, it failed gradually. The laptop was working fine for the first 14 months. One day I turned it on and the screen had some strange characters all over. I restarted the laptop right away and after that the video worked fine for a few days. Later I got same characters on the screen again but this time I couldn’t get rid of them. Finally, today my laptop video failed completely. There is no video when I turn it on. The bad thing is the laptop is not covered by the warranty anymore. Is it expensive to fix it?

I have my Nec Versa laptop which works perfect when turned on. However when I switch on the power, the front blue power light turns on but without anything on the screen. I have to force the blue light off by pressing down the power switch. I try the turn on/off process for quite a while until the screen finally starts. This process irritates me because sometimes i have to make so many trials or even give up. Any ideas about the causes and solutions?

First of all, I would check the memory modules. It’s possible that one of the memory modules is not making good contact with the slot or failing.

Try reconnecting both memory modules and test the laptop.

Try removing memory modules one by one and test the laptop with only one module installed. When the faulty module is removed, the laptop should start properly.

Try installing different memory module into different slots on the motherboard. It’s possible not the memory module but the slot itself going bad.

I have a broken LCD on a HP Pavilion DV6-2157 notebook. I don’t see any screws on the bezel. How do I replace the LCD on this model? Any info would be helpful.

You are correct, this model doesn’t have any screws on the screen bezel.
In order to remove and replace the LCD screen you’ll have to separate the display panel from the laptop base first. After that disassemble the display panel and remove the LCD screen.

All disassembly steps are shown in this service guide for HP Pavilion dv6 series notebooks. This is a 5.5MB pdf file and might take some time to download.  The display panel disassembly instructions are on the page 70.

My 1.5 year old laptops LCD screen after 6 month use started showing 1 horizontal white pixel line (well the line color kind of depends on what colors are above the line but usually it’s white) after 3 more months second appeared and today I spotted a third one now it’s one 3 pixel thick line at the near bottom of the screen. I found that it’s monitors fault because it always shows. However I found a trick to TEMPORALLY FIX IT: by easily pushing left top monitors corner forth and right top corner back the line disappears and appears again if I release the corners.

This description sounds like a problem with the LCD screen. Unfortunately, when the laptop screen starts showing lines like that, it cannot be fixed.

You’ll have to use the laptop as is with lines or get ready to replace the whole LCD screen.

Laptop screens used to be very expensive but these days you can find a brand new replacement screen for less than $100. Try eBay, there are some cheap LCD screens there.

My Toshiba Satellite’s LCD stopped working. I tested by attaching an external monitor to it and the display works. I couldn’t figure out if it was the back light, LCD, or inverter. I’ve shinned a flashlight on the LCD and cannot see anything. Though when I dim the lights, I see the LCD lite up. Does anyone have any ideas?

Your laptop works with an external monitor and that means the motherboard and video card work properly.

It’s possible that the video cable got disconnected from the motherboard. I’ve seen it happening before a few times in some Toshiba Satellites models.

You’ll have to remove the laptop keyboard (go to www.irisvista.com for disassembly help for Toshiba laptops) and take a look at the connection between the video cable and motherboard.

If the video cable connector is half way out, push it back into connector on the motherboard. This might help to fix your problem.

My Dell laptop has been giving me these strange horizontal and angular lines and dots on my screen with different characters on the text as well. Tried reloading fresh windows and drivers but still the same.

If reinstalling the operating system doesn’t help, it’s definitely a hardware related failure.

First of all, test your laptop with video output on the external monitor.

If both, the external monitor and laptop screen show exactly the same problem, this is the video card related failure. In most laptops the video card is integrated into the motherboard, it means the entire motherboard has to be replaced.

If strange lines appear only on the laptop screen and the external monitor works properly, the problem is somewhere inside the laptop display panel. It could be one of the following:

1. Poor connection between the video cable and motherboard or LCD screen. Try reconnecting the video cable on both ends.
2. Defective video cable. Try replacing it with a new one.
3. Failed LCD screen. In this case you’ll have to replace the screen.

I have Toshiba Satellite M305 laptop for past couple of months my laptop screen is giving me problems. Sometimes my screen would have like horizontal lines and after while screen will get blank but I can still see backlight is on. If i turn it off and turn right back on it will work fine for couple of hours and it will start flickering and go back to same thing. So I don’t know if this is inverter problem or lose connection with my LCD cables.

Most likely this problem is related to the video cable. In some Satellite M305 and Satellite M305D laptops Toshiba installed defective video cables made by CMI.

It is necessary to disassemble the laptop display panel and take a look at the video cable. If the cable part numbers starts with letters CMI, replace the cable.

I really doubt that your problem is related to the inverter failure. A bad inverter board wouldn’t cause horizontal lines on the screen. Also, you said the screen goes blank but the backlight stays on, it means the inverter works properly.

If your Satellite M305/M305D laptop is still under warranty, call Toshiba and they will fix it at no charge. I’m not sure if you have to pay for out-of-warranty laptop repair. Maybe not because it’s a known issue affecting many laptops. Try calling them even if your laptop is not under warranty anymore. Please let us know if Toshiba fix it for your at no charge.
