If the LCD was physically cracked or broken, then yes you should be able to swap it for an undamaged one.
The cheapest option for you is to advertise or look on Ebay for an identical model - also with faults, but with an undamaged display. (maybe dropped - sold as not working)
- this is just like yours - but also has the cracked LCD. You need to search for one with a good display.
Take this "donor" apart first to see how it's assembled, then just swap the parts.
This method of repair is common for consumer electronics.
