Since some weeks, my OPPO 103EU is not recognizing Pure Audio Blu-rays anymore.
Not only the ones with the "PureAudio" logo (which use the color buttons for switching the audio formats), but all my HFPAs from Universal as well. All Blu-rays, which only have one static menu page from which music is played are affected by this problem. It only says "Unknown Disk".
The firmware is the newest one (BDP10XEU-83-1226 from 2017) and I didn't change anything in the settings.
I've reflashed the same firmware - with a full reset to factory settings of course - but the problem remains.
I've cleaned the persisting memory and disabled BD-Live, as suggested in the FAQ.
Then I thought, replacing the laser unit will help.
A KM480 is easy to find and not expensive, so I've tried it. At first, only the optical unit. After no success, the whole frame with motor and spindle drive for the laser as well. (To be sure, that I don't have speed problems when the motor starts to spin, for example) Now everything, that could wear out is new again.
The positive thing: its easy to do that, and it didn't make it worse.
Everything still plays flawlessly - Blu-rays with video content, SA-CDs, DVD-Audio/Video etc.... except for my complete PureAudio BD collection
Disks with intro films and animated menus - like Sgt. Pepper or White Album (Deluxe) are no problem.
What makes it even more mysterious: a ripped copy, burnt to a BD-R works.
OPPO support doesn't have an idea until now.
Anything else I could try?
