Hello, I'm Shahid, I'll be happy to assist you. I need additional info of TV symptoms to troubleshoot the problem.
This is not an answer so do not rate it.

- Does TV display normal picture during that one minute?

- Do you see any distortion/ abnormality in picture before TV shuts Off?

Thanks.

Thanks for the info, it seems either logic control board or main board internal failure, I would swap logic control board as first thing to see if it fix the problem or the main board is culprit and need to be replaced. Please check following board supplier link to get required logic control board for this TV.
