I have a toshiba satellite A00 Series labtop. My monitor went black and I tried a sugeestion about taking out the battery and putting it back in but my labtop's monitor still doesn't work. My labtop itself is fine however. I'm assuming it's a backlight problem. How much would a backlight cost for my model and where would I find it under? I'm looking to repair it myself and not bring it in for repair so take that in mind when saying the cost. Any help would be greatly appreciated.
