Hope someone can point me in the right direction (LCD Screen, Crimped Cable, Backlight, Battery?????)

I have a Toshiba L505D-S5992 Satellite laptop. Recently the display began to dim after the laptop screen is lifted to a certain point (i.e. 1/2 way). The symptoms after hitting that 1/2 mark (same every time) are consistent with an Inverter/Backlight failure. I replaced the Inverter and still have the same problem. The LCD is normal (no spots, lines etc… until the LCD screen is lifted to 1/2 way then the screen Darkens to black although you can still feintly see the image if you shine a light or look closely enough. Attaching an external monitor works fine.

I think this is problem with the video cable. Most likely the backlight fails because the vide cable not making good connection with the motherboard or the video cable is defective.

Here are a few things to try. You’ll have to go though some laptop disassembly steps.

1.Remove laptop keyboard and reseat the video cable connector on the motherboard. Make sure it’s plugged correctly, all the way in. Test laptop after that.
2. Access the back side of the LCD screen and reseat the video cable connector on the back. Test laptop after that.
3. Replace the video cable with a new one.

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.

I have an HP G60 and the screen keeps going dim…but when I close and open it it comes back up for a few seconds or so..I’ve tried fn + f8 but it does not help and I’ve tried adjusting the power plan when it gives me more than ten seconds to do so…please help!

Most likely it’s either failed screen inverter or failed backlight lamp inside the LCD screen. Which one is causing the problem? You cannot tell without testing the laptop with a known good inverter or LCD screen.
Both the inverter board and backlight lamp have very similar failure symptoms.

If you don’t have spare parts and have to guess, try replacing the inverter board first. If it doesn’t help, replace the LCD screen.

This guide explains how to get inside the laptop. This is guide for HP G50/G60/G70 notebooks. Also, will work for Compaq Presario CQ50/CQ60/CQ70 notebooks.

Also, your problem could be related to the video cable or motherboard but it’s not very common.

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?

My screen on my HP Pavilion dv6-1259dx is broken (hit with a pillow, and has funny lines all over it) How do I change the screen on my own. I cannot find any screws for the top where the screen is, like all the sites say to find?

Your Pavilion dv6 laptop should have eight screw covers on the front bezel.
Remove those eight covers and remove all eight screws hidden under those covers.
After that you remove the bezel and access the screen.

You’ll find detailed instruction with pictures in the service manual. This is a 5.5MB pdf file and might take some time to download.

The display panel disassembly instructions are shown on the page 158 in the “Recycling” chapter.

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.
