TCD D8 DAT Walkman strange issue

I have this Walkman. I have gone through it and repaired everything that I saw on the 4hr video on yt. After putting in a tape that it records it plays for a minute to 1:30. Then the screen goes blank and it resets. Does this maybe 2-4 times. I noticed that if I ff and rew it to beginning it works at least the last time.
