Tape transport help for TASCAM Porta 2 Ministudio

[circusparade]

Here’s the video showing my problem: https://drive.google.com/file/d/1t9STngB0Nm_yKD9pbtq6zx_TKWzkyRhJ/view?usp=drivesdk

Basically, when put it into play, the pinch roller is stuck in the pause position and it automatically returns to stop as if it’s gone to the end of the tape. It won’t stop if pause is on. Is it something wrong with the belts? The motor? Any help would be helpful.

Welcome to the board.

It's hard to see from the video. Is the capstan spinning when the power is on?

Have you taken this machine apart at all yet?

Yes, the capstan is spinning. I took it apart when I first got it (for curiosity more than anything), but that was months ago, and before this problem cropped up
