Hi guys, what do you think is the problem of my Rotel RCD 12. It has a slot-in CD loader. Lately whenever i play CD, playing stops at track 5 sometimes track 10! Is it a weak lens issue or just misalignment? Unlike the tray CD loader of the usual CD player, i cannot see the lens of the RCD 12 as it is enclosed in metal box. What can you recommend? Or can you point me to a CD player doctor?
