HomeToshiba Satellite L305D or L305 stopped showing video on the LCD screen. Video on the external monitor works just fine but nothing appears on the internal screen, it’s completely blank. What could be wrong?
The LCD screen doesn’t work because the video cable got disconnected from the motherboard.
I have seen a problem like that on a few different Satellite L305D laptops. Not sure why it’s happening but check this out.
In order to access the video cable connector you’ll have to remove the keyboard first.
Using a sharp object lift up and remove the keyboard bezel.
Under the bezel you’ll find two screws securing the motherboard. Remove both screws.
Lift up the keyboard and place it upside down on the palm rest. Be careful, the keyboard is attached to the motherboard.
You’ll find the video cable connector under the keyboard.
If you look very closely, you’ll see that the video cable is half way out of the connector on the motherboard.
Plug the video cable back into the connector and test the laptop now. Does it help?

I have acer aspire 4715z with problems on the lcd, which only shows a white / light without seeming the least writing or drawing.
approximately situated where the damage? on the lcd, the inverter or something else?
thanks for the reply.

boetix,
It’s not the inverter failure. That’s for sure. You still can see the white screen, so it’s not inverter or backlight lamp failure.
1. Try reconnecting the video cable on the back of the screen. It’s possible the cable got disconnected or not seated correctly.
2. If reconnecting the cable doesn’t help, it’s either bad LCD or motherboard. I cannot tell. I’ve seen both causing the same white screen.

ty,
Sure. I posted LCD removal instructions here: http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L305-L305D/remove-screen-replace-video-cable-1.htm
There are three pages in the guide.
Good luck!

Thanks, I thought I had an inverter or screen problem on my Toshiba Satelite, L305 but your post helped me find the cable unplugged.
Thanks again,

Laptop Tech,
I used your information to fix my computer and I made a small donation. Great idea, and I hope it works for you.
Thanks,

This was exactly my problem. I was told it was probably inverter but I found this site and checked this connection before buying the part and works perfectly now.
thanks,

How about a funky color screen?
Getting green snow on the boot up and it’s all out of whack color-wise in Windows. Toshiba L305.
I’m guessing it’s the video cable going bad…which is weird because all I did was unplug it from the motherboard doing another repair! I’ve tried playing with the connection but can’t get it to show properly.
(oh and the repair was for the broken power jack…works & looks great once I got that up and running!)
Thanks…great site!

YOU BEAUTY!!! This fixed mine, thank you so much, was looking at a repair costing £100+!!

Matt,
Did you test laptop with an external monitor? I assume the external image is fine?
Take a closer look at the connection between the video cable and motherboard.
Take a look inside the connector on the motherboard. I hope you didn’t bent pins inside the connector (happened to me before a few times).
Again, make sure the cable seated correctly. If the problem still there, I guess you should try replacing the video cable.
Maybe reconnecting the video cable killed it.

Yep looks to be. External image fine. Just replaced video cable, same screen showing.
Looks like one of the pins on the connector to the motherboard is missing…if it’s supposed to be, OK. If not, may be where my issue lies…and yes, all I did was unplug it initially then on the re-plug and re-boot I got this.
I thought initially it was just bad Windows drivers…but that wouldn’t affect it in BIOS…I’ll give it a shot there, but otherwise it’s likely the shop for this.
Thanks!

Hi there, I am having the same problem… I tried to do this but nothing happened. My laptop works on external screen but I can’t use it always like this. Is there any other issue that causes this to happen?

@ Blink,
If the laptop works with the external monitor, most likely your motherboard still operates properly.
Your problem could be related to one of the following: failed LCD cable or failed LCD screen.
You said reseating the video cable didn’t help, so I assume it’s not connection related issue.
By the way, you should try reseating video cable connector on the back of the screen. Maybe it got loose.

I have same problem as Blink and I reseated in both connection and still black screen.
What else can I do ?

Hi, same here and did reseated video cable in both connection and still the black screen.

@ Danshibai,
1. Try replacing the video cable.
2. Try replacing the LCD screen.
I cannot tell which one is failing in your laptop without testing it with spare parts.

Hello again and thanks a lot for answering. I sent my laptop to repair and it turned out it was a problem with the mother board. It works, but some chips (or that’s what they said) weren’t sending the power to the monitor. So they fixed it and I was able to use it for a day. The next day when I turned it on it didn’t work again. I sent it, they said it was the same thing and fixed it again. I used it without turning it off, instead of that I put my laptop on sleep mode to use it again the next day. I did these the whole weekend but a program asked me to restart so I did it and surprise, it didn’t show anything again.
I sent it again yesterday and they said probably the motherboard wasn’t able to take the repair at all. I am upset because I payed them and they said it was going to work fine after that…
I just have a question, is it possible something else is going on and they haven’t noticed? They replaced the inverter too, by the way, and charged me it because it wasn’t working either (or that’s what they said…) and none of the other parts seem to be the problem.
Thank you and sorry if I make mistakes, english is not my language.

I forgot to say this: I read it could be the CMOS battery. I am not sure what this does and also I don’t trust the people who are “fixing” my computer. Could it be that? If it doesn’t work again I will ask for my money and take it somewhere else.
March 14th, 2012 at 12:33 pm
@ Blink,
It’s hard to tell. If they were able to fix laptop video temporarily by replacing some chips on the motherboard, probably this is motherboard related problem.
I don’t think so. Laptop backlight problems not related to the CMOS battery.
March 14th, 2012 at 1:23 pm
Thank you again. So it is possible to repair the mother board? Becuase they said now it is possible I need a new one, but I don’t get why it works fine if I put it on sleep mode and not when I restart it.
March 14th, 2012 at 4:58 pm
@ Blink,
I don’t know. I don’t repair laptop motherboards on the component level. If a motherboard fails, we replace it with a new one.
March 25th, 2012 at 7:42 pm
My video cable looked seated fine and I was about to order an inverter to try to get my backlight working but after reading this article I unplugged and replugged the video cable and now it’s working fine….thanks….so I guess it just wasn’t making good contact…this laptop hardly ever gets moved so it was puzzling.
