Toshiba M105-S3015 --No Back lite

PC seems to be working fine and will run an external monitor. The internal screen has a picture..mouse pointer and does what it should except no backlite. Replaced the inverter with a new one but no luck. Also; what is the voltage out of the inverter to run the backlite?

It is difficult to measure the voltage as it takes a very high voltage to get the light to strike and runs about 90 - 100volts to sustain it. Is the lamp OK?

SOURCE: laptop screen in complete darkness but external monitor works fine

I have a problem with my hp laptop monitor's hinges, could you link where you were able to purchase those hinges?

Also, make sure you monitor's ribbon cable isn't missing any wires or that all of those wires are fully contacting.

SOURCE: I changed the inverted in my toshiba satellite

Sounds like the screen itself is bad or possibly the plug is bad to the inverter or motherboard.The videocard sounds like its ok.

I would like to boot a toshiba satellite m105-s30401 with an external monitor as the laptop screen is busted and i would like to use an external monitor until i get a replacement screen, how do i get


Connecting an External Monitor or Data Projector
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

External monitor only works if I start windows vista in safe mode


First after you boot it up normally (not Safe Mode) can you move the mouse far to the left or to the right do you see the mouse. If you do see the mouse pointer you are running dual monitor mode and the laptop screen is set as the primary monitor. You have to run it in Save Mode and set the external monitor as the primary monitor. Hit the Start button then select Help+Support and in the search box enter "dual monitors". Read how to set up the primary monitor.

Second maybe you need to activate the external monitor. When laptops boot normally (not Safe Mode again) with a external monitor connected you have to hit the Fn (function) key (probably blue near Alt key) and some other number key (it probably has a blue monitor symbol on it) I'm not sure which one. This key sequence is a toggle sequence. In other words when you boot a laptop it goes directly to the laptop screen then the first time you do a Fn + number key combination it will turn on the external monitor and turn off the laptop screen the next time you push Fn+number key it will turn on both monitors (external and laptop screen) the third time it will turn on only the laptop screen and so forth.

If you had the same problem with an external mouse and cleaning the screen doesn't help, I suggest you may need to download some newer drivers from Toshiba.com or have a virus.
Run a good anti virus programme, like Norton to clear it.

I have a toshiba satellite m105-s1021. when i turn it on, i hear it running but the screen stays black...so i pluged vga to it. works fine there...looked around for errors, none, updated drivers,but no...


Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp

Satellite M105 S322 Display very Dim. The PC works fine with external monitor but the LCD display is dim and cannot see anything on the screen


You have lost your backlight which is a thin long bulb built into the bottom of the screen itself. You have the option of getting the backlight by itself and rebuilding the screen or buying a new screen assembly and changing that out. Below is the service guide to change the screen.

Mouse pad cursor doesn't work


try using the FN key with the monitor/VGA output selection changer(usually F5). You will see a little icon that looks like two monitors. Mouse control may have been changed to the external monitor connection. See if pressing FN(function) and holding that key and then pressing the monitor key will bring back your mouse indicator. You may need to do it with the projector connected and on.

When I turn on the Toshiba Satellite A215-S7447 laptop, the monitor part of it doesn't turn on with the rest of the system.


Plug in an external monitor. use the <FN><F5> keys to toggle between the internal lcd and the external monitor. If the display external works and the lcd doesn't, most likely a bad inverter board.

My toshiba m105 it wasn't the inverter, it was the lcd itself, the TAB welds were no good but the lcd still worked it just had a 3" vertical blacked out area on the lcd.
