I have a Toshiba A135-S2386 Laptop running Vista Premium. Just the other day when I went to start it the lights come on but my screen is completely "Black". No images what-so-ever! I was wondering if anybody could tell me if this is caused by a Bad Inverter or a Bad LCD??? I can buy a New LCD pretty cheap and can replace it myself no prob, but I don't want to do that until I'm sure that's the reason it's "Black". Thanks, Rob
