it sounds like a hardware problem. I would say your high voltage board that drives your lcd has blown probably the caps you buy new on-line and replace it. send to factory service to have fixed. get fixed on warranty if you have it.
please let me if I helped
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

If you cannot find the reset pins try to find the CMOS 3V battery, it is usually located under the keyboard, and disconnect it. remove the computer battery and then start the computer. When you boot it should ask you for the time and date. At this point shut down and plug the CMOS battery back in and reinstall the computer battery. This time when it ask for the time and date go ahead and enter it and the rest of the bios should be set to default.
