Toshiba Satellite M55 laptop is a pretty new model with 14.1-inch TruBrite widescreen display. The guide will show you how to open laptop display assembly if you want to remove and replace the screen. Even though I didn’t picture the battery removal step in my guide, you should always start laptop disassembly with removing the battery. The LCD screen mask is shaped a little bit different then on older laptops and it might take more time to remove it from the display assembly. I usually start LCD mask removal around the hinge area. Place fingers between the mask and the screen and wiggle it a little bit until you feel that latches are released. It is hard to explain how much you have to flex the mask not to crack it, just be very careful and do not hurry. After the latches on the bottom of the mask are released, you can start separating the mask from the display assembly on the sides and finally on the top. The FL inverter board in this model is located under the laptop speakers. To get access to the Fl inverter board cables you have to unscrew the speakers and put them a little bit aside. The best way to find a spare LCD screen is to use a Toshiba part number on the back of the screen. The part number can be located on a sticker and it look like this: K0000270850

I’m repairing an M55 for a friend. The video is intermittent but mostly absent. It’s a black screen with the back light on. When I unplug and plug the monitor (see picture) you can see the video momentarily. I checked all the connections and they are tight. Any ideas as to what could be the issue?

Hello.
I have a Toshiba M55. When I boot it up there are verticle lines running the length of the screen beside right. It does this on occasion but in the past it has corrected itself. I thought it might be the video card that was loose because it usually occurs after the computer is bumped or I carry it around for a while. I am at a loss as to what the problem is so any help would be much appreciated. Thanks!

Hi,
My M55 comes up immediately with a grey/white screen sometimes and other times it is normal when I turn it on. I wiggle tweak and twist and it does not affect the grey screen. Hooking up an external monitor works fine.
I have heard get a new LCD panel or it might be the inverter. I presume that the video HW is integrated into the motherboard.
Is there a diagnostic to narrow it down? Can I probe the inverter board with a DMM and see if it is not powering up?
Thanks.

once you remove your laptop screen you have to press in the circuit board strip gently to see if that improves the clarity of the screen. it worked for me. the red lines went away.

If I get lines on my LCD to the point of not seeing anything but lines, and if I squeeze the top bezel and it clears, is there something loose or is it a bad screen

Have a Toshiba M55 with a screen that gets lines all across it. If you hold the bezel tight up at the top lines go away as if something is loose. Do you think that is the case, or is the screen bad?

my problem is the same as 19’s. I didnt see an answer. i did all the screen disassemble parts , the ribbon is fine on the top, moving tha doesnt change it, but the screen clears immediately if you let the back hang down applying pressure to the bottom part of the ribbon cable, as soon as you raise it the screen goes screwy again. how do i reassemble maintaining pressure to keep screen clear?

Julian,
It looks like you have a problem with the LCD screen. I don’t think that you can fix this problem at home. You’ll have to replace the screen.

jay,
What kind of line do you see? Are they running through the whole screen?
Test your laptop with an external screen. Can you see the same lines on the external video?

Hi, I have a Toshiba Satellite M55. Suddenly my LCD screen took a greenish look but it look normal when I connect it to an external monitor or if I make some pressure in some parts of the screen or if I move it in some directions. Any advise about how to solve this problem?
Thanks,
Julian
