Display stopped working on badger 2035 (from GutHub Universe)

Hi Team,
I got my badger from GitHub Universe last year and it was hanging in my room not used for 1 month. I connected it to laptop, and all text diapered and now I see only rectangle of random pixels. Sometimes after restart it started blinking black/white, but only this rectangle area from photo. I can upload files via Thonny. I think I even managed to nuke it, but still this same.
Any idea? Is it dead?
