Thanks for such a detailed email, you've done a great job, and it definitely
helps us work out where the problem might be.

I'm no expert, but from what you're saying, my call would be a dead LCD
screen. I don't believe that the changes you have made could have caused
this issue, and given that the external display works, it seems as though
the video card and drivers are all OK. It looks as though you've done most
reasonable checks and eliminated the obvious (and some not so obvious!)
issues. How old is the machine? Can you contact Toshiba for a warranty, or
if it's too old, a replacement LCD panel? (I'm not sure how easy the LCDs
are to replace on the Toshibas, I've never attempted it, but they should be
able to advise you).

Does anyone else have other suggestions?



Cheers! Lana

we can, improve the solutions, and pass them on.
