Toshiba Satellite M45. Removing LCD screen and replacing FL inverter board
Toshiba Satellite M45 display disassembly guide will help you to remove the LCD screen and replace the FL inverter board. It is very easy to take the laptop display assembly apart, but you have to be careful. Never use screwdrivers to separate the LCD mask from the screen top cover! To remove the LCD screen mask use your finger. Put your fingers between the LCD mask and the screen and start separating the mask from the LCD screen cover. Sometimes, when the mask plastic latches are tight, I use a guitar pick to disengage them. I put the guitar pick between the mask and the top cover and slowly move it along the side. The screen mask is made of very thin plastic and you can easily break it if you not careful. After the mask is removed, everything is straight forward. In this model the video cable is glued to the LCD screen so you have to use some force to separate it from the screen. When you unplug the inverter board cables do not pull the wires. Use the connector edges to unplug it.

Jerry,
The RTC battery in a Satellite M45 laptop is located on the motherboard. Take a look at the laptop disassembly guide, you can see the RTC battery on the step 26. It’s on the left side from the Intel chip on the bottom of the image.

Where is the RTC on an M45-S169?

Yes there was an image after it the ground. I will check the motherboard coonnection.
If it not that any other ideas?
Thanks

Bob,
Did you get any image on the LCD after the laptop was dropped? Did the original LCD light up after that?
Make sure to check the video cable connection on the motherboard. It’s possible that the connector got loose and has to be reseated.

I just replaced a new LCD screen in my Toshiba Satellite A105-s4054. Everything is hooked upcorrectly, but I am not getting an image. It appears not to have power. Did I miss some switch I need to turn on to get the backlighting to come on. The computer was inital dropped and the LCD was smashed. I do get a image on a CRT. Thanks

Does anyone has problem with M45 S331 LCD dim image problem? I replaced the FL inverter and it worked for a few hours only? Can it be other circuitary problem?
Thanks

Hi. Mine is an M45 S351. I’ve got the same problem as Mike (comment 8, works fine in Safe Mode but freezes in full mode after various intervals ranging from a few seconds of desktop to an hour or more. I’ve have tried everything suggested to no avail. Safe Mode with networking is fine for surfing, OpenOffice and most text/graphics but sounds, music, films etc freeze. Could there be a problem with the audio part of the motherboard? Any suggestions gratefully accepted.

Before anyone breaks anymore laptops, pull the rubber pieces off from each corner and take the screws out. The repair will go much more in your favor…

I am in the same boat with the screen not working. I am considering replacing the complete screen. My screen worked fine, then one day it started having a red hue when I would start it up or bring it out of standby. After a couple minutes, the screen would be normal. Then one day it started blinking and moving, and then days later it died completely. I am wondering what this Toshiba LCD INVERTER part is and if it could be a cause?
Any help please. Thank you.

I was in bed with my Toshiba satellite tablet when the screen went completely blank although it was still on. Thought it was caused by a low battery or connection problem but after turning it off and back on there was nothing on the screen even when you can hear the computer boot up! Tried to connect to monitor and still nothing. By the way the screen does swivel.

Someone brought in a Toshiba Satellite 1805-S204. With the LCD screen and inverter connected, the laptop will work fine and look fine, but then turn off after about 5 seconds (completely off). If you hook up an external monitor and don’t use the LCD, it works fine. If you disconnect the backlight harness from the inverter, the laptop works fine, but of course you have no backlight and the LCD is very dark and unusable. Does this sound like a faulty inverter causing some sort voltage spike and killing the laptop?
P.S. I we have tried all the normal things like re-seating RAM, dvd, etc. All troubleshooting has come down to this: with backlight unplugged everything is fine, with it connected the laptop powers off seconds after being turned on.

I have a Toshiba Satellite M45 and whenever I start up the computer, a Microsoft error report pops up and says that I have a problem with my FN key. Whenever I press down the FN key and F6 or F7 to brighten up my screen, it doesn’t work. I have already sent the error reports but Microsoft still hasn’t fixed my problem. Is there an easy way to fix this?

Jorge, I don’t know ur motherboard but your computer looks similar to a Satellite A105. she won’t boot from The cdrom if by chance she can try putting a password disk in and take that chance. If no avail then to get the pics of top & bottom of the motherboard beause besides a repair shop to go in is the other way. A guy by ElRiver told me his board has 2 contact point(pad500) told to him by a reseller,I don’t have 2 points. So once he was inside he crossed them with metal to clear the passwd. If u have none then try the battery removal unless it’s soldered. They say to cross the battery contacts(+&-) but I can’t say that’s safe. Last it’s the bios, on A105 phoenix doesn’t even label it so you will have a tuff time finding it cause it not conventional looking. Then you have to cross 2 contacts which hold the passwd memory.On line u can find similarities to the bios contacts but u have to have a good sence of skill on this also in the HD is the control panel there’s a program that controls the passwd(lol), urs is a sata then u will need to put a USB enclosure to access to another computer. If u can get in make ur way there and work on it, if not take out ur info,then format it, and try to boot again. These are last minute resources unless as I said there’s the repair shop which if they don’t charge alot go for it. That’s all I found out and as I’ve said I’m in the same boat as u, and I’m ready to shock the shite out of this battery because the owner has collision insurance on it and he’s ready to claim it, got luck Yagis.

I had a problem with the backlight on my Toshiba M45-S331. I bought a new FL inverter board and installed it a month ago. Everything worked fine. Yesterday it quit again. It comes on for a short period of time and then goes out. I can see a dim image when that happens so I know it is the same problem. Is it possible to replace the backlight, or do I need to replace the whole screen?
You have a very good website. Thanks!

What is the best way to extend the range of the WIFI card in an M45-S2693? You mention an FL inverter pcb-what is the purpose of this?
Thanks for your site!!!!

Where do you find replacement display screens? I own a Toshiba Satellite M45 S3553 and my son knocked it off the counter and the screen looks like someone shot it.
Help!

Nevermind the above the comment because I found out how to take off the frame!
However…as careful as I tried to remove the frame, some of the plastic teeth snapped. Reassembling the frame also resulted in unpleasant snapping sounds (Unfortunately, I ended up using double-sided tape to secure areas where the plastic teeth had snapped).
January 4th, 2007 at 5:28 pm
Hello, I have a question about removing the 4 corner masking seals. Are they bolts or just buttons glued down to hold the LCD frame in place, because I’m afraid once removed I cannot put it back together.

Thanks for providing such great information! Do you happen to know where I can locate the part number on the FL inverter? I have a Toshiba A25-S307, and, based on my research, it appears that there are two possible replacement inverters, P000354880 and P000352650.

I have a Toshiba Satilite M55 . It recently fell off the couch. When I turn it on , it appears to work fine except the screen is dim . I can barely see an image , it looks like some one put a black screen in front of it. I was thinking it might be the Fl inverter board. Is there any guide to show how to repair it, Also where could i get the new part. Is it worth trying to fix or have a professional do it? I dont want to buy a new computer because it has a lot of my information for school on it. Its my baby, thanks for your help

I have a toshiba M45-S351 and it will only stay on in safe mode (no matter how many times I reinstall or what version of windows I use). I also tried loading Linux (Fedora Core 5) and something in the way linux checks the hardware shut the machine down immediately. Computer stays on in safe mode for a long time (will still freeze every now and then) but will not stay on for more than 5 min in regualar mode. I have checked the heat sink and it is clean as a whistle. I was wondering if the FL Inverter might be a problem? I am not even sure exactly what the FL Inverter does. Thanks for any help or advise you guys can give in advance.

I was just wondering what other tools can you use to separate the LCD mask from the casing? I have broken a few levers in the past and want to figure out how to not break them in the future.
November 27th, 2006 at 12:37 am
Carlos Perez,
First of all, why do you want to replace the backlight? Are you sure it’s not a faulty FL inverter board? Here’s my post that has some laptop video troubleshooting tips.
The backlight bulb itself is located inside the LCD screen, on the bottom.
November 21st, 2006 at 9:42 pm
I need to replace the backlight for a Toshiba Satellite M45-S331. Could you please advise where the backlight is located (at the top or bottome of the screen). And brief instructions on how to replace it.
Thank you

Sharon,
I have created a guide for Toshiba Satellite A105 LCD screen removal and replacement. You’ll find the guide here: http://www.irisvista.com/tech/

I have a Toshiba Satellite A105 S361, and need to replace the screen. Are the procedures the same as the M45 discribed here?
October 8th, 2006 at 11:03 pm
Lindsay,
Assembly process is kinda opposite to disassembly. You do the same steps but backwards.
October 8th, 2006 at 10:55 pm
I just bought a new LCD screen for my M45 S331 and I was wondering if it is easy enough to attempt on my own? and I see this says how to take it off, but do you know where I can find instructions on how to put it back on i just want to make sure i do this right! So if thers any advice id highly appreciate it!! thanks!
