Hello to all...
I'm from Portugal, and so my English is a bit poor.

I'm writing this message because I have a BIG problem. I've a TI-86 calc. One day I loaned it to an ex friend (you'll realize why is an ex friend) because he wanted to play with one of the games that I’d installed in her. The next day, he delivered me the calc saying that she was strange. When I see it, I couldn’t believe in my eyes. The LCD was broken in an half. I told him to pay for it, and he said that it wasn't his fault and didn’t talk to me again. I'm writing this message to ask someone help. I understand a little bit of basic electronic, but I don’t understand how to connect an LCD. I'm asking where I can buy online a cheap LCD to change by the broken one.
Please help. I need the calc...
Thank you for the answers...

EN:
you could try ebay but i dont think it will be easy to find, it would be a better idea do buy a new calc.
