Having a dead LCD screen is common with Toshiba laptops. M friend was having the same issue with his Toshiba laptop, but the whole screen turned into red. If you want to fix it then take it to Jareer Bookshop. They won't be able to do that in Sofitel, Jareer is selling those Toshiba laptops and their workshop guys do fix those. Just give it a try and let me know.
