Welcome. I am Mike, an experienced field technician. We are now connected together on this convenient website where I am able to help you.
Sorry there is not any magic fix for physical damage. The screen is one big assembly. The only way to fix this is to replace the entire screen which would cost more than a new tv.
I do understand that finding out your tv needs expensive repairs is not pleasant.
Let me know how else I can be of service and before you go please take a moment to submit at least a 3 star rating at the top of this page. Then if you still need help you can reply back and I will be happy to assist you further.
