Replacing the original resonators on main board, with oscillators it have impact over both picture and sound. The impact it is subtle but obvious. It mean less noises on picture (even cleaner picture), and higher quality for digital sound out of the device. The LPS it reduce dramatically the overall noise in the system, while the oscillators (powered by battery) it contribute to lower even more the noise levels.

Default Oppo 205 nosing after regulator change

Last night I changed the two regulators on the audio board to the newclassD uwb II regulator and I lost the audio for all outputs..Coaxial, hdmi and RCA.

Wonder what I have done wrong that causes it.

Hi Mok
Based on you PM, I think you have the regulators reversed. +ve reg LM2940 is near center of unit and -ve reg LM7912 is near the edge.
Here is schematic of physical layout, showing TPS7A regulator pinouts as well.
Ignore the bottom part which refer to a "4 pole bd"
