SACD Player Won't Play Hybrid SACDs


A few years ago I purchased a used Sony SCD-C555ES SACD changer. I bought it to use essentially as a CD player run through an external DAC. I have about 500 redbook CDs. A couple of days ago I bought my first SACDs and began playing them. Everything worked fine until tonight. For some reason, the same SACD hybrids that played fine several times will not now play in SACD mode. I get the message "Not Hybrid" and the player defaults to CD mode. I toggle between "Multi and 2 channel" and I get the message "Not SACD." Any ideas?

On my sony 5400, you can only play sacd in sacd mode with the internal dac. The digital output only works with redbook.
Sounds like weakening laser/read - lifetime is about 2-3years. Change the optical
assembly and you should be fine. Can be had from e-Bay for around $30-60 depending
on models.

My old dCS was fitted with Sony's SCD555ES equivalent, and I had to change them out
(optic assy.) once every 2-3years. Basically similar problems you encountered.
I dropped the SCD-C555ES off at the local Sony authorized repair shop. The place has an excellent reputation and does service work for just about all brands. The problem is the optical assembly. They're waiting for the Sony part to come in. Should be good to go.
Jjpeepers, good to know.. However if you plan on keeping the player for long, it is advisable to keep another sealed optic assy. as spare - it is getting scarcer by day. Depending on humidity, the problem could be an unpredictably recurring one. With Part at hand, should take no more than one hour to have it professionally replaced.

*For your easy referral, Part is : Sony, Device Optical, KHM-230AAA
Thanks for the info. Some problems have developed in attempting to get my unit repaired. There are now apparently 3 part numbers associated with KHM-230AAA. The original part # was 8-820-132-02. That was replaced by 8-820-132-03. The repair place ordered this part. It arrived, but was defective and was returned and another one ordered. Three weeks have passed and the part has not come in. Apparently, this part has been replaced by 8-820-132-09 and even this may no longer be available.
Is anyone familiar with 8-820-132-09 and is it now the "new" part for the SCD-C555es?
