Toshiba function key display problems

on boot go to setup, make sure you have display set to LCD and not external monitor, if still a problem after boot, wait for windows sound, hold function key down and press the F4 key (or what ever function key looks like it has a monitor /lcd symbol on it, mine is the F4)

Hi,
Does the display show anything before you enter windows? If yes, then press the key to transfer video back to your original screen once you enter windows. It should be the function key "Fn" + F5 - F8. looks for the icon which shows a monitor or says "CRT/LCD".
If it doesn't show anything before you enter windows I'm afraid your screen needs to be replaced. Good luck.

the Fn key amd the brightness direction keys are the only keys to operate the brightness.
There is a limit stop Min and Max brightness that the function will reach and that is built in

To enable or disable wireless communication, use the Hot Key
Fn+F8.

To use the Hot Key Cards:
1 Press and hold the Fn key.
The TOSHIBA Cards appear along the top of the screen.

2 Click the Card for the system function to be modified.
The selected Card is displayed full-size with its available
options below it. All other Cards are again hidden from view.
3 Click the desired option.
To use a Hot Key Card using a hot key:
1 Press and hold the Fn key.
2 Press the hot key associated with the desired function.
The associated hot key card appears at the top of the screen
with its available options below it.
3 To cycle through the displayed options, hold down Fn and press
the hot key repeatedly. Release the Fn key when the desired
option is selected.
NOTE

Hi:
One way to determine if just the screen is bad is to connect a computer monitor to your laptop and toggle the display to it, and if you have a picture, the lcd or inverter is bad on your laptop. Usually all you have to do is hold down your function key and then hit the display mode key, on my laptop it is F8

Start - All Programs - Toshiba - Utilities - Settings for Flash Cards
--
then just place a check mark in the box labeled "DisableToshiba
Flashcards"

Just download this :) It will fix your problem. If it doesn't work, just search for Toshiba Value Added Package Vista/XP (that depends on what Operative System you've got) and download for your Operative System.

As far I know FN keys are related with specific motherboard drivers.
Thoshiba recovery cd/dvd during restore/re-install, loads all toshiba drivers and utilities for operating fn keys.
If the operative system loaded in the laptop is no OEM then you will have this problem, and in order to fix it you must:
First install the operative system (clean install)
Second install: chipset drivers. This drivers instructs the operative system how to detect specific hardware. Must be installed in first order.
Third: install drivers (ethernet card, audio, video controller, toshiba utilities, etc). At this point verify all FN keys ( check display settings, stand by/ hybernation, etc).
four: Load all software needed (microsoft office, etc).

I hope this help to solve your problem

What model is your Toshiba? I haven't heard of one having a weird multi-display like that, so more than likely it's a problem with your graphics chip than a feature. Look for a function key that either says CRT/LCD, or has a picture of a monitor. Hold down the Fn key and press that function button and see if it makes a difference.

Is the system locked up at that screen?

LCD issue it needs repair..call tosh if your laptop is still in warranty
