LCD Display only the second row is working

can somebody help me?
I made a weatherstation with kind of different sensors.
I wanted to get the Diagrams of the temperature on the lcd display. At the start everything worked, but then i built a casing and now it doesn't works any more.
Thanks for your help

A Faraday cage, by any chance?

Might be.

What if you remove the casing?

Then you could make a picture, for us to get a general idea about your issue.

guys it worked thanks for your help and your time
