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.

I have a Dell Inspiron 1525 and it wont turn on. I mean i can turn it on but it doesn’t go directly to windows like it always does but instead it just does a blank screen with a blinking cursor on the top left. Before my laptop just freezes and turns off by itself or sometimes freezes then a blue screen appears and then after 2 weeks that thing happened it doesn’t turns on. Please please please help me!!

Sounds like this is hard drive failure. The laptop starts with a blinking cursor on the top left side of the screen because it cannot see the hard drive or the hard drive doesn’t work properly.

You can test the hard drive with SeaTools utility available for download from Seagate site. This utility works fine for most hard drives and can tell you if your hard drive is failing. Download the utility, burn it on a CD and boot the laptop from this CD. Run hard drive diagnostic test.

If the hard drive fails test, you’ll have to replace it with a new one and reinstall the operating system. You can reinstall the operating system from the recovery disc which usually comes with the laptop. Insert the recovery disc into the DVD drive and restart the laptop. It should start booting from the disc. Follow the instructions on the screen.

My Dell Latitude laptop will not power on. It was slow for a few days and I was able to get Windows to load once and found that the battery is at 96%, so that is not the problem. Now I cannot even get it to load windows. The green light flashes for a few seconds then goes out.The fan doesn’t come on and Windows never loads; it just goes off. I think I may have a virus, and want to reload Windows, but can’t even get it to power up or bring up the reboot menu. What can I do?

1. Try starting your laptop without the hard drive. The hard drive can be easily removed from the bottom. If the laptop tuns on and loads BIOS screen, most likely have a failed hard drive.

2. If removing the hard drive doesn’t help, remove all other parts you can access except memory modules. Remove the battery, DVD drive, wireless card. In short, minimize the system as much as you can. After that try turning it on from the AC adapter. If the laptop gets power from the adapter (light turns on) but will not power up, this could be motherboard or memory failure.

3. Try removing memory modules one by one. Try tuning it on with only one memory module installed. Try different slots. If the laptop fails with each module, most likely this is motherboard related failure.

You can backup personal files from the hard drive using an external USB enclosure.

My Acer Aspire Notebook turns off all by itself just after turning on, or after Windows shows up. I can hear a click from inside, than it’s off.

First of all, turn on the notebook and listen for the cooling fan. Does it spin at all? Usually you can see the cooling fan though the air intake grill on the bottom of the notebook. If the fan doesn’t spin, it’s possible you have a failed fan and the notebook turns off because of overheating. If that’s the case, the cooling fan has to be replaced.

If the cooling fan works properly,listen for the hard drive sounds. It’s possible you have a failing hard drive. If the hard drive makes clicking noise, it’s bad and has to be replaced.

If the hard drive is failing, you still can try recovering data using an external USB enclosure.

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 dropped my dell laptop, now it turns on & shows the xp windows logo. I notice the the booting bar is in activation but it does not stop, ever.

Most likely you damaged the hard drive.
Listen closely for noises coming from the hard drive when the laptop tries loading Windows. Can you hear repetitive clicking noise or grinding noise? If yes, the hard drive was damaged.
Turn off the laptop as soon as possible. Hopefully you still can recover personal files from the failing hard drive.

If the hard drive was damaged, you’ll have to replace it with a new one and reinstall Windows OS.

How do I take apart a Dell Inspiron 1000 in order to re-solder the jack plug? Thank you

I hope you understand that you’ll have to disassemble the whole laptop and remove the motherboard in order to fix the DC jack, right? You’ll need some computer repair and soldering skills.
If you are ready to go, here are step-by-step instructions for replacing DC jack in a Dell Inspiron 1000 laptop.

1. First of all, before you disassemble the laptop, make sure you have a brand new DC jack for your laptop.
I would recommend replacing the old jack with a new one, not just re-soldering it.

2. Get step-by-step Dell Inspiron 1000 disassembly instructions here. With these instructions you’ll be able to remove the motherboard.

3. Finally, read though this DC jack repair guide. It explains how to desolder the old DC jack and replace it with a new one.

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.
