Marantz SA-14 acting up


This is an older player and has been a good one but now has developed problems. When you try and load a disc, the tray closes very slowly and then opens right back up. Any ideas please?

It sounds like something is jammed the transport. I would take the cover off and look inside.

I lubricated the slide last night which didn't seem to do anything at the time but, by morning, the tray was going back in as normal.

It's taking longer to a read a disc but still plays and, BTW, what a difference between it and the Rotel I was using as a back up. The Marantz sounds awesome in comparison!

Thanks to all that took time to comment, I appreciate it!
