After 5 months of frequent use (I watch one movie a day on average, and listen to CDs a LOT), my 9000ES stopped playing SACDs. When I put in an SACD, it only allows me to play the CD layer. Sometimes I need to hold the PLAY button while the disc is loading, just so that I can play the disc. I think this undocumented technique bypasses the disc error checking(?). This way I can play the SACD layer, but then after a few minutes into the disc, it stops playing with the "C 13 00" (bad disc?) error being displayed. When the player was new, I occasionally had this problem but only with multichannel SACDs (of course, played in 2-channel mode). I thought it was just a problem of the discs and not of the player. But now, it seems that all my SACDs wouldn't play properly. So it seems that the problem is getting worse. What are the possibilities here? I doubt if it's an electronic problem coz DVDs and CDs play perfectly. Can it be that the lens simply needs cleaning? If so, are the lens cleaner discs, those that come with a fluid, effective and safe? Anyone else had this problem? How did you solve it? Any suggestions will be much appreciated.
