Removing LCD screen, video cable and inverter from a Satellite A105 laptop
Here are instructions for getting inside the display assembly on a Toshiba Satellite A105 laptop. You can use this instructions for removing and replacing the LCD screen, video cable or screen inverter.
If you are only replacing the inverter board, you don’t have to remove the screen. The inverter board is located right under the screen and is secured to the screen cover by one screw. Just remove the screen mask as it shown on the step 6 and then remove the inverter.
If you are replacing the video cable, you’ll have to remove the LCD screen and also remove the keyboard strip. The video cable connector on the motherboard is located right under the keyboard strip.

I have a Toshiba P100, my daughter drop the laptop about 1 tear ago. After that starting to act funky, it started to turn off right after I turned it on, this does this for 3 or four times, then unplug the power and it works the 5 or sixth time, then it runs fine. The next day when I try to turn it on it does the same again. I replaced the mother board, cpu, power buttom board and ram, what could be the problem. I tried with and without battery. Thanks

I have a Toshiba Satellite A105 and my screen seems to be having issues with its back light. If i move the screen to a certain angle the back light works fine but if it is bumped or moved it will flicker like a strobe light or just go out! I think the LCD screen it self is fine as i see the display with a bright flash light ever when it seems to be out. So do you think i need a new inverter or ribbon?
I would greatly appreciate any advice!

“I have a toshiba satellite a 105 and the LCD no longer displays anything. Before the screen went blank, sometimes tilting the cover back and forth would cause the display to work. Could this be a problem with the ribbon cable?”
i wouldn’t think its the ribbon cable because that’s for the screen itself, i would think its the inverter, less when you say it displays nothing you mean that the screen is on but its black, then I’d say its sumthing like that cable or the screen.

Aw that sucks i just got same problem from bringing laptop to school in backpack with books on it, and no i have that issue with 1/3 of screen fading out, sure their aren’t anymore remedies?
(i kinda just had to buy a new hard drive for 120$ a new external hard drive for myself 70$, and my uncle a new external hard drive for around 50$ because it failed wile i had borrowed it, my bank account isn’t infinite…)

lee,
Sounds like the LCD screen failure to me. I think you’ll have to replace the screen.

my A105-S2712 at times has a vertical red line on the screen.
but the big problem is the bottom 1/3 of the screen freezes while the top 2/3 can still be normal. Moving the lid back and forth affects it and sometimes remedy’s it but it must remain perfectly still to continue. The curser disappears if you move into this area but reappears when you move back up. any idea what is wrong? thanks lee

hi
when i turn on my toshiba satellite pro a100, i get a black screen(the screen is working but its black). i tried to plug my laptop to an external monitor, i turned off the laptop restarted it and on the external monitor i see windows loading but with floating boxes, line and blurry picture. it doesnt enter windows and the screen is black.
i want to know if thats a graphic card problem because if it is i can change it (pci express).
my graphic card is Schnittstelle: PCI Express
Grafikspeicher: 256 MB
Chipentwickler: NVIDIA
Grafikchip: GeForce 7600 GO
if i consider that the video card is the problem, i cant find any that is 256mb and looks exactly like 64mb card.
i appreciate any help i can get

DANIELLA,
It’s hard to tell. Check external video. Are you getting the same problem on the external monitor?
If external video works fine, it could be:
1. Bad connection between the video cable and motherboard.
2. Bad video cable.
3. Bad LCD screen.
4. Defective motherboard.
I cannot tell without running some diagnostics.

ok my husband satallite a105-s2101 screen is a pinkish color on a constant basis, you can see all other colors but everthing also has a pink tint to it. and the white parts are all pink…what could be wrong? please help

I have a Satellite A105-S2101, Model Number PSAA5U-01300O. The screen image rolls and flickers. I have have to rotate the screen from the closed position (0 Deg)to the totally opened position(180 Deg). It is getting harder and harder to get the image to settle down. I’m guessing this is a video cable issue. How do I get a replacement one?

great write up and pics! i just replaced my crack lcd screen and wanted to leave a couple of comments.
step 6: don’t need to remove that screw as i didn’t need to replace the fl inverter board
step 8: actually, there are 4 smaller screws holding the screen to the hinges on each side. i suggest getting a eyeglass repair tool and take your time as i stripped one using an exacto-blade and had to drill it out so i can use the eyeglass tool.
otherwise, fairly straight-forward and simple. i actually found a cheaper screen after i already bought mine on ebay for roughly $60. having it serviced would’ve cost me over $400!
thanks and happy computing!

Thanks for pointing me to that thread. It seems it is exactly what I need. As the procedure seems quite difficult and risky, I decided that I can live with that one spot near the corner for now. I’ll reconsider if it gets worse.
Thanks for all your answers.

umiki,
It’s possible but not easy. Take a look at this LCD disassembly guide. If you doing it without any experience, most likely you’ll damage the screen.
May 18th, 2009 at 6:03 am
Thanks for your reply! So there is no easy way. I thought that I should not take it apart (on the disassembly pics, it did not look as it was possible). My personal experience about the removal of dust from sensitive parts is that I either end up with more dust (plus particles, fingerprints etc.) or it takes ridicolusly long time.

umiki,
Yes, it’s possible that you got a piece dirt inside the laptop. How it gets in there? I don’t know but it happens.
In order to remove it you’ll have to disassemble the LCD screen and I would strongly suggest not to do so. You can damage the screen. Just use it as is.

Hello,
I have a Toshiba A100 (which looks very similar to the A105 on the pics). It is about two and a half years old. A few days ago I noticed a dark spot near one corner. It is about 5 pixels, but it does not end on pixel boundary and by looking at it, it seems that it is behind the pixels. I guess it could be dust between the light source and the panel. Is that possible? Is there a way to remove it?
May 13th, 2009 at 12:28 pm
Well I hook it up to external LCD noting happen?
May 12th, 2009 at 2:52 pm
Matt,
You can find a replacement inverter using the part number from the original inverter.
1. Disassemble the display panel.
2. Remove the inverter and find the part number.
3. Google the part number.
May 12th, 2009 at 2:51 pm
Matt,
If the external monitor works fine and you can see a very dim image on the internal LCD screen, it’s likely that you have a failed inverter board.
May 12th, 2009 at 2:50 pm
Hello people! My buddy just a gave me his a105 to fix the LCD doesn’t light up at all is it the possibly inverter?
Thanks Matt

mila,
On older Toshiba laptops you can clear the BIOS password using this method.
Will not work for newer Toshibas.
April 14th, 2009 at 1:13 pm
Michel,
I agree with T Wyrick,
Sounds like a problem with the LCD screen. If the screen lights up, the inverter works properly.
Also, T Wyrick said:
If your screen has one or few thin vertical lines in random places, it’s bad LCD. The problem is not related to the cable.
Again, sounds like a bad screen.
April 14th, 2009 at 11:43 am
Michel,
The issue you describe with the lines of lost pixels? That’s a bad LCD display, not the inverter.
If you can make the lines light up or go out based on twisting the screen, that indicates problems with the circuit traces on the LCD display board itself, or possibly with the flat ribbon cable that goes from it to the motherboard.
February 14th, 2009 at 4:35 am
Great Instructions. Need help diagnosing whether my problem is the inverter or the LCD screen itself. Started losing a line of pixels about 9 months ago, they would all come back if I twisted the screen a bit. Then one line turned into 2 right next to each other, then 3 with one of missing lines of pixels above the original two by 3 inches.
Again, twisting the screen worked well.
Then, all the pixels beneath the original 2 all would phase in an out, but twisting would help for a while. Now, after I opened the Screen Mask and fooled around with the video cable, all the pixels between those original 2 lines stay out and rarely come back no matter what I do.
Is this an LCD screen issue, Video Cable issue or an inverter issue?

Good day; was wondering if you knew where the lcd switch for a toshiba satellite a20 was. It does not appear to be plunger type switch. Could it be a magnet type, if so where would it be located. Did not see anything or any reference to it in the disassembly guide

hi bill, my laptop problem need password bios… how to fix that…

How can I tell if I need a new display or if its a inverter or lcd cable. Apparently my customer dropped it.. the screen is not cracked but one does not get a good picture.. it flickers when it comes on then you can not make out the screen. I can hook it to an external monitor and fn +f5 I think it was.. switched to the external and the machine works fine.
Presuming then the lcd cable and inverter are ok? Or bad presumption.. since the external is working without those parts…
Please advise
Thanks in advance,
Jim

I have a toshiba satellite m105. the port on the motherboard where the cable from the lcd connects to the motherboard was scorched when something shorted out. i do not have money to replace the computer or the montherboard. is there a way to fix or replace the port?
