I checked the belt. It’s not messed up or anything and it turns just fine but when I put a cassette in the walkman it doesn’t play as if the turning pegs were stuck? And then I have to open the walkman back up and turn a white wheel thingy in there just to reset the belt. Also I couldn’t find the Wm-fx407 on select a device so I hope it’s acceptable for me to post a question on the wm-fx407
