My phone has power but sometimes only shows coloured lines flashing.

I dropped my phone and the screen went black. When it came back on it showed coloured lines flashing. After 2 days of not working it came back to working but that afternoon I lost it again to the coloured lines and sometimes black screen. The blue light at the top can still flash so I know it's getting power but can it be fixed or does it sound like a big issue and should I get a new one?
