I have a Toshiba A105-s2716 satellite. At first the screen would start flashing. The screen went black and sometimes gray horizontal lines would appear. It would then turn black and go back to normal. After a week now, the screen will stay black after ten minutes of using my laptop. It works fine with a external monitor, many people tell me that its a hardware issue. My warranty expired so I’m trying to figure out the problem before I have it fixed. I need to fixed my laptop ASAP because i need for college.
I’ve seen this problem with Satellite A105 laptops before and I believe the culprit is the the motherboard. Even though the external video works fine, it’s still a problem with the motherboard. I think there could be something wrong with the video chip or with the video cable connector. Unfortunately both the video chip and the video cable connector are soldered on the motherboard. It means the whole motherboard must be replaced in order to fix the problem.
Update:
Please read comment 44 posted by Andy:
I tried to replace the whole LCD panel, but it didn’t help. I was going to buy a new laptop, so I just wanted to mess around with the old one. First thing I did – I upgraded BIOS to most current version. I did it just to see how BIOS upgrade works, and it fixed the problem!
It’s possible that Toshiba fixed this problem with the latest BIOS release. I tried updating the BIOS before but it didn’t help, apparently the BIOS version with the fix wasn’t available back then.
I will try it as soon as I have to repair Satellite A105 with a problem like that.

Jay,
I fixed many laptops with no image on the LCD screen simply by reconnecting the video cable. I’m glad you fixed your problem. Very good troubleshooting steps!

Ok, Satellite A105-2101 Powers on fine but screen is completely black. I connected to a external monitor and the external showed up fine. Read all the post and began working.. Turned it off then rebooted and held down FN+F5 and nothing, then removed battery and bezel to check connector on the back of the monitor. I unplugged it then plugged it back in and still nothing. Updated to the latest BIOS and nothing. So I pulled the battery again then the keyboard strip so I could get to the monitor plug on the motherboard. Pulled it out then put it back in then put everything back together and powered it on. The screen came on with no problems on boot up….. Thanks everyone……

Oops my bad, I see that the connections are soldered in place on the motherboard from the first post. Then what connections are needed to be check to make sure they are connected at the motherboard.

My toshiba A105 is having problems with the screen. Similar to others there are horizontal lines that distort the image and will get progressively worse until there are vertical lines and you can see no image. Vertical lines are like #1 here http://www.laptoprepair101.com/laptop/2006/08/17/bad-video-on-lcd-screen/
Only thing is that its only on the lower 2-3 inches of the screen. I have put a external monitor on and there is no problems with that image. If I am lucky moving the screen will produce a image and sometimes it will stay and others it will start with the horizontal lines.
I have checked the back of the LCD and everything seems connected there, tonight we are going to open it up to the motherboard and check there.
My questions are could the LCD be bad only in that section and are the connections to the motherboard soldered in place or plugged in that could be loose.

Tanushree,
Sounds like a problem with the video card. I think you’ll have to replace the video card if it’s a discrete module in your laptop or replace the motherboard if the video card is integrated.

Dan,
I think it’s bad LCD screen. You’ll have to replace the screen.

Hello, i am working on a A104-S4034. The LCD screen displays black and blue lines, it seems like the owner has already tried to update the bios. The monitor output still works fine, I am thinking it might be the LCD controller board.
The following address will take you to a photograph of the screen

Well took the laptop apart while I was awaiting (your fast) reponse. The cable is plugged in, and it appears to be plugged in on the back of the lcd screen. I’m going to slap this back together and try to see what happens.
Thanks…
