Cost of getting the required items would make it not worth while, ribbons are very fragile and takes a skilled hand to deal with such when it comes to soldering ribbons to circuit boards, but whats the point if the screen is cracked anyways.
If you really want to fix it your going to need to buy a new screen at the very least.
The screen is most likely going cost more than it;s worth,i guess you could buy the same model and maybe ( HAHA ) one day you have spare parts but other wise.
When i was replacing parts on my LG finding ones with broken screens is very easy and the other parts can be found cheap, the screens the most expensive part typically.
