If it doesn't bother you using non Toshiba parts then you could repair it for about £60-100.
If you do want official pparts then i suggest just buying a new laptop, and cut your loses.
I deal with laptop repairs at work, and the quotes for original parts are extortianate at more than double the price.
Dell wanted £210 for the screen, a further £60 for fixing, and postage on top of that.
None of our Toshibas have been damaged whilst i've worked there, so i don't know their pricing.
What model is your laptop?
