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.

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?

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?

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.

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

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.

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.

i have a toshiba satellite m45 and it keeps locking up on me

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!

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.

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.

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.

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 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?

My laptop LCD is dim, but when I connect an external monitor the laptop screen becomes bright again. Any ideas?

Victor,
Check out these instructions, but it’s not easy. You can easily damage the screen while replacing the backlight lamp. Be careful.

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.

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.

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

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?

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

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 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
