Laptop LCD lost signal

I'm thinking your laptop screen may have died, If it's under warranty you can send it back to its manufacturer (make sure you backup your data first) or If it isn't I'd recommend either A) sending it into a computer repair shop, it's not too hard to replace laptop screens so-long as they have an identical one in stock or B) consider an upgrade.

If you wouldn't mind can you please supply your current specifications and a price range if you were to upgrade, and a location too.

Thanks,
Joe
