I have Toshiba satellite A15-S129. I replaced the notebook screen I could only get WHITE BACKLIGHT no image at all.

I have Toshiba satellite A15-S129 notebook. I have cracked the screen but could still see around and under cracks. I take the screen out by using your Toshiba Satellite 2435 instruction (thanks for the help it was easy), when I reinstalled the screen I could only get WHITE BACKLIGHT no image at all. I hooked up the external monitor and got an image but goes back to laptop and just white light. I remember when I first dissembled the notebook display assembly and reinstalled the old cracked screen that it look to me like the data connector cable (male) on the back of the display laid on top of the LCD connector(female) and I taped it down. Later when I looked again at the connector I realized it plugged in and not laying on top. I also notice the data cable has open pins on it which I made contact with the metal surface of the LCD connector. Did I short something? The External monitor does display starting Windows XP.

From my experience, very often you get a white screen when the video cable is not properly seated on the back of the LCD screen. I assume that the video cable is good itself, because you were able to see some image on the old cracked screen.
Disconnect the video cable from the connector on the LCD screen and check the connector with a magnifying glass. If you see any bent pins, very carefully straighten them with a small flathead screwdriver. I hope that you didn’t break any pins.
I’m not sure if you can short a circuit, but I’m pretty sure that you can damage pins if you plug the video cable incorrectly. I’ve done it myself before and I was able to make it work after I straightened bent pins on the LCD connector.

    I have an HP dv8000. I also have a lcd problem. It has been working fine but then the screen started to go black and then when I moved the screen to a certain position it worked. Now a few months later it is mainly white. But when I slightly twist the upper left corner towards middle it works fine. But I have to hold it for it to work. PLEASE tell me it is not the screen. I can’t afford 200 bucks right now (who can). I am in the Air Force and am going to be deployed soon and I need my laptop to work so I can communicate with my wife and kids easier. Please help.

    Hans-Peter,

    I tried to connect the bad TFT to another Laptop with sure intact motherboard, and wonder it was the same problem. When I connected the good TFT from the other laptop to the motherboard of the bad TFT the good TFT worked without problems. So the Motherboard is OK and there must be something wrong with the display.

    This sounds like a problem with the LCD screen. I cannot tell you what exactly is wrong with the screen but you’ll have to replace the whole screen.

    Hi I have a problem with white screen two, but there are two big differences.

    My Dell Inspiron 6000 with 1920×1200 on 15.4 inch TFT worked fine all the time. Suddenly it got White (not quite white, but glowing) but there are two differences.

    When it starts, I can see the BIOS POST (in deed I see the Dell-LOGO while the BIOS POST), but when it should change to Start-Menu or if I want to enter the BIOS —> glowing but no picture.

    So I started to connect a external TFT (it worked), booted Windows and then something interesting happens. If the Notebook-TFT turns off the backlight (power saving) and I rewake the Notebook-TFT (with the mouse or keyboard) then I have a picture (backlight AND Picture) for about 1 to 2 seconds. After this it gets glowing white again.

    I tried to connect the bad TFT to another Laptop with sure intact motherboard, and wonder it was the same problem. When I connected the good TFT from the other laptop to the motherboard of the bad TFT the good TFT worked without problems. So the Motherboard is OK and there must be something wrong with the display.

    Any Idea what there is going on ?

    I tested it with an external monitor and it shows nothing either. It’s almost like it has to warm up before it boots up. I replaced the memory with two gigs of new ram and still the same thing. The cd tray won’t open either while it’s doing this. When it finally comes on, everything works great. This is really weird.

    Mike Parker,

    but it takes 10 to 20 minutes for the laptop to show anything on the screen.

    Test the laptop with an external monitor. What about the external video, it works the same way?

    Hello, I have a Toshiba Satellite M35X , when I press the power button it lights up and some lights on the front of the laptop come on and the fan spins for about 5 seconds but it takes 10 to 20 minutes for the laptop to show anything on the screen. I did a low level format and a clean install of xp pro but it still does this. Once the laptop comes on everything works great. If I click restart it shuts off and comes right back on with no problems. I’ve never seen one do this before, any suggestions?

    Mike,

    Does any one know where i can source for a 14.1? true bright wide screen?. i have a HP Pavillion dv2200

    I found it here.

    the screen is giving out lines sometimes it goes blank so i guess its the screen

    Could be connection related issue. Before you buy a new screen, try reseating the video cable connections on both ends – on the motherboard and on the back of the LCD screen.

    Update: Fresh install of XP on formatted HD worked. I guess the moral of the story here is you might as well try the software before you start assuming a HW problem.

    Hi. I have a Compaq Presario 2100. The LCD monitor has gone berzerk, lots of flickering (looks like vertical hold is messed up) and some distortion of the image. The external monitor works fine. Interestingly, on startup and on the log in screen, the LCD shows the image a lot better (virtually no flickering and distortion for the most part) than when logged in and looking at the desktop.

    Is the LCD bad or possibly inverter? Thanks for your help.

    Do you know what connections do I need to make to detach the LCD screen from my Laptop Toshiba Satellite 1905-s303 so it can be added as a secondary monitor in another computer? I would need to connect the monitor cables to a VGA connector, but don-t know exactly how.

    Sounds like a wire came loose during the reinstall we ran into this before on compaq and dell notebooks.

    Check your connections first, then trace back,also are their any lines on the screen either horizontal or vertical if their are it reveals another situation too.

    We are still checking on this for you and may use your question live on air next time we are on.

    If you find the fix before then asw e will share with others.

    Hi,

    I have a Toshiba M30. Yesterday, right after I started the computer up into windows XP, the screen went completely white. I immediately plugged it into an external display and the computer was working as it should except for the LCD display. After doing some researching, I removed the keyboard and reseated the video connector. I also did the same for for the LCD side (remove bezel, unbolt the lcd, peel back copper tape and reseat connector). The LCD screen is still a steady WHITE (expect at Windows XP startup where i believe it changes screen resolution. This is where it flickers black to white). I know the FL inverter is working because I am still able to adjust the screen brightness using the “FN” key. Do you know if it is a bad LCD or just a bad video flex cable? Is there any other type of diagnosis that I can use to narrow down the problem? Thanks in advance!

    hi… i’m praying that you can give me a little insight… i have a Toshiba m35-s3592 with a white screen with 2 vertical bands(VERY slightly grey). i’ve read over the previous post, and have done the folling things: reseated LCD vid cable (both ends) checked for bent pins, swisted, tapped, stared at, and used swear words. i can hook the laptop to a CRT monitor and it works fine that way. i recently had to “rewire” the cooling fan. for some reason, the mainboard? wasn’t powering the fan, so i pulled it out and tested it with a 5 volt power supply, and it was working fine. well.. since USB is 5 volt, i sacrificed my rearmost USB port, and used the 5 volt supply to it to power the fan. that worked great. i was just tooling along on the net and i closed the lid. when i opened it back up i got my normal screen for about 5 seconds, then it quickly fades to white. i can’t think of anything else to check. since the screen is lit, the inverter should be good, but i dunno. thanks in advance for any help

    I have a Toshiba Laptop Satellite A-65 1064 that has started to become show to display the screen. When the computer is warm from a previous use I do not see this Problem. The proble is that when the laptop has cooled down at initial startup I get a black screen with white horizontal lines that appear randomly … disappear and randomly reappear. This continues until the unit warms up and then all of a sudden I get a full bright screen after about 2-6 minutes. I have hooked up a separate display monitor on it and it show the up without all the random white lines.

    Loose connections, Bad Inverter or Bad Backlight?

    Your Thoughts!
