I’m in the same spot on a CDT-1. Original behavior was skips and errors reading disk. Replaced with eBay laser, player always says “no disk”. Replaced they with official ARC laser, same issue! I feel like there must be some sort of ESD solder blob I’m not seeing? It doesn’t even spin the CD. This is exactly like a Rega unit I repaired, before I realized there was a solder blob that needed to be cleared. Can anyone point me in the right direction?
