You can buy it, if you rich and lucky
I've seen(google it) new lcd unit online for $200, however they out of stock
How I fix it (short version) - don't try fix old flat connectors, remove it. they are too old and too fragile. (actually you can try glue it too, however in my opinion this would be even more work to do.)
create a new one and glue it. this is some kind of "jewelry watch" work.
There are about 49 connecters to glue, so be patient
and buy a good magnifying glass.
I did it twice, it took me about 4 hours for first, and 2 hours for second.
Both works now great
