I picked up a dark gray and orange MZ-DN430 MD player and it will barely play any MDs. I insert the disc, it spins up while making a very feint vibration feeling/noise and will just sit there not playing the track. Sometimes if I skip to the second or third track, it'll start playing but usually stops after about 10 seconds or so and makes that same noise/vibration. I ran a Discwasher MD laser cleaner through it thinking that could help but it didn't do anything (I don't know much about these things). Anyone know what problem I'm having and how to fix it or know someone who can fix it? Thanks for any help you may give me!
