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.
Are you looking for the whole laptop disassembly instructions? You’ll find them here.

Lindsay,
Assembly process is kinda opposite to disassembly. You do the same steps but backwards.

I have a Toshiba Satellite A105 S361, and need to replace the screen. Are the procedures the same as the M45 discribed here?

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

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 29th, 2006 at 1:08 pm
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.

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 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
December 20th, 2006 at 11:41 am
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.

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.
January 4th, 2007 at 7:58 pm
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 23rd, 2007 at 5:21 am
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!

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!!!!
March 1st, 2007 at 6:59 am
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!

i have atoshiba satellite m45 .and it needs bios password..how can i resolve this issue? remember this particular model doesn’t have afloppy drive so i cannot flash the bios.any ideas please repply at jorgediazmc@yahoo.com
thanks:TT:Jorge Diaz
March 27th, 2007 at 11:14 am
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 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?
June 5th, 2007 at 2:30 pm
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.
June 6th, 2007 at 5:52 pm
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.
June 13th, 2007 at 10:30 pm
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.
June 18th, 2007 at 6:54 pm
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…
July 20th, 2007 at 3:07 am
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.

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
August 7th, 2007 at 6:08 pm
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
August 7th, 2007 at 10:55 pm
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.
August 8th, 2007 at 12:52 am
Yes there was an image after it the ground. I will check the motherboard coonnection.
If it not that any other ideas?
Thanks

Where is the RTC on an M45-S169?
August 26th, 2007 at 8:20 pm
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.

Hi I bought a Toshiba Satelite Pro A120 2 GB Dual Core with a smashed screen. I replaced it with a new one. It is very dim but works perfectly with an external monitor. Is there a difference as how to connect the pink and white wires to Backlight inverter as I broke the connection for this. Dont know the part No. for new Backlight Inverter
September 11th, 2007 at 11:05 am
I have replaced a broken lcd screen with a new one on Amilo M7440 laptop. The problem is that the machine starts but very dim and the function keys for brightness do not change the brightness. I can log on to windows xp but the screen is barely visible. Very dim. I suspect the backlight converter. If this is the case which I put to the panel, where would I get a backlight converter?
Thanks

Hello. I’ve got two toshiba satellite, (M45-169 and M30-801) The M45 has the lcd wxga(glossy) broken and the M30 has the mother board broken. I would like to know if i can put the screen of the M30 (mate) in the M45. The only thing it is no compatible are the wires for the inverter. Does anybody knows if there is a problem if i cut the wires of the mate screen (M30, green and pink) and match them with the inverter of the M45 (white and pink).
Thnks

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 ok. But two days back the problem comes 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. I tried to find out the real problem. But fails. I touched at the tips of the backlit with a probe of mulitmeter then its work better, when i remove it then the diplay goes off. i think some internal oscillation error is going on. Any body have any idea pse email me

My inverter does not need to be replaced, I was just stupid and cracked the screen, do I still need to remove that or can I skip that step?

Question on cables removal from motherboard on M45 series STEP 17
Although this probably holds true for every model, I am unsure how to remove the cables from the mother board without breaking the locking tabs.
I had to remove a similiar style cable on a Playstation 2 and broke the locking tab but was able to use tape to keep the cable from moving when I did reassembly.
Is there a special tool that is used? I am thinking a guitar pick but that seems too wide and probably break the clips.
thanks, tom
August 17th, 2008 at 1:14 pm
Thomas,
There is no special tool. You can open the locking tab with your fingernail.
Carefully lift one side of the brown locking tab up. When it’s opened it stays at a 90 degree angle.
August 30th, 2008 at 8:12 am
Hello I read Toshiba Satellite M45. Removing LCD screen and replacing FL inverter board. The only thing is that I just need to replace the backlight not the whole LCD screen. With this being said I was wondering if you have a step by step for just replacing the backlight? If so I would greatly appreciate the instruction link or an email with the steps. I came a cross your website on searching for the instructions and this website by far was the best. Great idea for the site and hope it will be around for ever, thanks.
August 30th, 2008 at 11:24 am
Victor,
Check out these instructions, but it’s not easy. You can easily damage the screen while replacing the backlight lamp. Be careful.

My laptop LCD is dim, but when I connect an external monitor the laptop screen becomes bright again. Any ideas?
October 2nd, 2008 at 7:44 am
I have a laptop Dell Sattelite Edition… anyways, my screen goes to a grayish type color and I was just wondering if it is a problem with the Black light bulb or the inverter itself?
October 13th, 2008 at 11:36 am
well i have a Compaq Presario V6560EA and I am wandering if it is possible to take off the cover that is around the screen in the way its done on the picture. let me know(hacker-eng@hotmail.com)if u done anything like this to compaq or hp laptop
October 14th, 2008 at 8:17 am
szpon88 :
As I’ve said before don’t assume things meaning laptops are similar in design but it’s the plastics that differentiate them apart from each other and to open one in the wrong place the wrong way will not allow it to snap together correctly causing you to buy a plastic part.
I will make life easy for you, click on this HP site and you will be able to look and download the manual for your laptop.

I have Toshiba Satellite M45-S169 that I am working on for a freind. I have replaced the entire LCD Screen and also added a new inverter. When the system boots up, I see nothing on the screen at the DOS level all the way through the initial Windows XP login. The screen display is extremely faint and the only way I can get it to fully light is to use the Fuction-F7 keys once the xp desktop is fully loaded. I’ve reloaded XP drivers, set BIOS defaults. Still the same behavior. I am at a loss. I need to return it to my friend, but It’s only 95% fixed. I hate to take it back him stating that he’ll have to hit Func-F5 everytime the system boots up. Espcially with the cost of the replacement LCD and the inverter. Any adivce would be appreciated.
December 15th, 2008 at 5:39 am
I have one of my Toshiba M45-S169 hinges misaligned. It is on the side where the power cord plugs in. My screen flickers on and off,if I press the screen down it is ok sometimes,or I have to tilt the screen at different angles for the display to stop flickering.
What needs to be done? replace the hinges or could it be a wiring problem?
Thanks in advance.
December 15th, 2008 at 7:55 am
Edit my previous post if possible. My display screen is scramlbed,I said flickers on and off,that isn’t the case,sorry for not being more accurate with my problem the 1st time.
March 5th, 2009 at 8:15 am
I have a Toshiba Satellite M45 that I acquired as a result of a class action suit 3+ years ago. Just before the warranty ran out the display started to cut out so I could not use the computer. The service people fixed it comenting that they resecured the display cable. A year later it acted up again and I was able to fix it myself thanks to your excellent web site. Thanks a bunch!

I have a toshiba M45-S165. it was worked fine yesterday (11/04/2009). Now the display is not working ,a darkness only . No power is going to monitor. The other things are proper functioning.I connected an external monitor,it is working. Please send me some instructions for how can i open it myself.Pls help me as soon as possible . My mail id is “rranji@gmail.com “.Thank you.
April 15th, 2009 at 11:30 am
Ranjith.kr,
Is it completely black and blank or you still can see a very faint image when you look very closely?
If there is a faint image on the screen, most likely you have to replace the inverter board. I linked to the disassembly instructions in my post.
April 15th, 2009 at 11:32 am
becky,
1. Check the memory. Run memory test. You can use Memtest86+.
2. Check the hard drive. Run hard drive test. Download utility from the hard drive manufacturer’s website.

I have been using my Toshiba M45-S331 since year 2005, almost every single day. A few weeks ago my screen started turning slowly white and when this happens the screen freezes. The problem has become worse in recent days. I have managed to use the laptop by putting pressure on top of the monitor towards left by a paperclip. My suspicion is that the connections have become loose. Do you agree with me? How can I fix this problem?
Thanks very much
July 20th, 2009 at 11:05 pm
my toshiba M45-s165 screen went black(no display at all).I connected an external monitor to the VGA port and is working fine.Help me.Is it the fault of “FL inverter” ? can i replace that?how much cost? From where will get this part in bangalore?
please help
July 21st, 2009 at 9:36 am
Ranji,
Is it really black? Take a closer look, maybe you can see a very dim image?
When inverter fails, you still should be able to see a very faint image on the screen. Can you?
Yes, it’s possible to replace the inverter board. I linked to the disassembly guide in the post.
August 17th, 2009 at 7:41 am
I have a Toshiba M45 Satellite Laptop. It has worked well. I have a problem with it now. It went to Standy-by, but now will not turn back on. No Power.
This same problem occurred about 2 months ago. After it sit for a while w/o the battery, it came back up and worked well for until last week.
Do you have any idea what the problem could be? I took it to Tiger Direct and they told me it was the power supply or motherboard? I just don’t feel they did anything.
Is there a CMIO’s Battery? If so, where is it located?
August 25th, 2009 at 10:08 pm
Paul,
It’s hard to tell which one is failing.
I don’t think it’s related to the power supply because when it fails, it fails completely.
You said the laptop will not turn back on and there is no power? Are there any lights when you plug in the power adapter of the laptop appears to be completely dead?
November 28th, 2009 at 5:36 am
I have an M45-S351 and the screen is kind of faint/diff colors at the sides.
There is also a white vertical line across the screen (this seems to be a problem with the connector, since pressing on top it changes color and even disappears).
Do you think I should replace the screen?
Many thanks in advance.
November 28th, 2009 at 12:31 pm
Sergio,
First of all, test your laptop with video on the external monitor. If external monitor works fine and the problem appears only on the laptop screen, most likely you have a problem with the screen and it has to be replaced.
December 8th, 2009 at 7:43 am
Hello,
This is Ranji writing this email from bangaore. I have a Toshiba M45 Satellite and LCD Fl inverter (Part-V000055570)gone bad and i need to replace it.I would like to know from where I can purchase this part in Bangalore and how much is the cost? If possible please provide the PH no or address of the retailer. Also I want to know about the price of LCD screen (V000050090). Please advice at the earliest.
Thanks and regards
Ranji

Hello I have a Toshiba Satellite M45-S331 and the screen is black if I shine a flashlight to the screen everything looks great no color drift or discoloration. I tried to replace the inverter but that was not the problem. Was thinking that the CCFL back light is bad. Just wanted to make sure and a repair step by step guide since this is a delicate process. Any help would be great thanks for your time.
June 21st, 2010 at 7:23 am
Victor,
I think you are correct.
If replacing the inverter board didn’t help, most likely this is the backlight lamp failure. You’ll have to replace the LCD screen.
September 29th, 2010 at 8:52 pm
i have a Satellite P30-109
the lcd screen do a vertical band near the rigth size that divides into 2 part the image on the screen
if i use an external monitor i view normal
do you think that cai i resolve with a new lcd ?
thanks Alberto

My wifes M45-S2653 Left Monitor Hinge Separated, the tension from the pin was to much for the part that secured it to the body. Is there a way to adjust the tension? i am hoping i can find part number TC7010-L SZS as that is all that is needed to get this old beast into working order.
May 31st, 2011 at 6:58 pm
My Toshiba Satellite has no hard drive in it. Does this make the screen black? I plug it to a monitor and can see the bois.
