Black screen blue light

Late last year after a full day of recording on my motorbike I didn’t use/touch my insta for a few days yet when I came to edit the videos I was met with a blue light and black screen.

And was informed my instas customer service that it sounds like a firmware problem as it wouldn’t do anything when connected to power and no battery and that I should send it back to clarify and as it’s not in warranty I wouldn’t be getting it back.

So has anyone else had this or anyway of fixing it?

Cheers
