LCD Screen Garbage On TAZ 5

I’m in the middle of a print and the LCD screen suddenly shows garbage. I’m using SD Card and print is continuing. Ribbons seem firmly secured on Rambo board and back of LCD, but waiting for print to stop before pushing hard.

Is this likely bad LCD screen, loose wire or electromagnetic interference somewhere?

When the print stopped I was able to firmly push the ribbons into the back of the LCD and noticed one was slightly loose. Problem solved.

It was kind of strange that for the last couple prints the LCD screen always looked fine when I turned the printer off then on. After printing for a while the LCD screen would get garbled…loose connections do strange things.
