Hi, I have a Toshiba Satellite Pro C660 with a blank screen. The laptop starts up and goes through its boot cycle fine, but nothing is displayed on the screen.

I've read through tons of forums, but nothing seems to work.

I did the whole removal of battery, power supply and holding the power button for 60 secs... still blank...

When plugging in an external monitor it works perfectly fine, so this eliminates any issues with the CPU / GPU / RAM / HDD, etc.

I re-installed windows 7, which would hopefully eliminate any software issues.

Next logical step was to check the LCD backlight, inverter and ribbon cable... So I replaced the screen, but still blank screen. Just as a side note, the backlight lights up with both old and new display, but no picture.

This leaves me to think that it might be something in the BIOS?

Any suggestions / ideas?

I suspect a motherboard failure at the spot where the ribbon cable connects to the MB. That socket may be at the edge of the MB and subject to added stress/damage.

I doubt it has anything to do with the BIOS.

Good Luck
