The power converter may have gone if its across the whole screen. If this is following any spillage or water ingress, you may get away with drying it out (esp the plug that goes to the display, as these ofter 'track' if wet.
Otherwise, the cheapest route is to buy another tosh 1200 from ebay and swap hard drives!
