Cayin SCD-50T service data needed

Greetings,

I'm seeking service data for my Cayin. It uses a Sony KHM280AAA transport. Current state is on a single layer SACD it spins up and attempts to read. Then defaults to "no disc" and even ejects the drawer. Hybrids it also first says it's attempting to read the SACD layer. But then defaults to the CD layer and boots up. It reads regular CD's but has more trouble playing those back than a hybrid type.

Also both audio outputs have some odd distortions that are frequency dependant. Like a tick of sorts combined with birdies. I noticed that the playback of the hybrid CD layer has considerably less distortion than a regular CD. For some reason the distortion rises on those.

Thx,
DD
