I have an older denon record player. It’s a 70s model and I’ve had it about 8 years. Last night I was playing a record and everything was fine. I went to change records. I took the first one off then put on the second one and hit auto start and walked away. After a few minutes it hit never that the record never started. I went back over to player and the needle was on the record but no sound was coming out. I’m not sure what’s going on. I have never had problems with it and it was just working right before. Anyone with any ideas ?
