BDP S185 No audio on disc or streaming

The BDP S185 seems to function well with the single exception that there is no audio. I replaced the network board, which handles audio, but still no audio. Is audio reliant on power not used for the other electronics? Does anyone have pinouts?

Thanks for any pointers.

ALL audio does not pass. From BD, or DVD, as well as from an internet stream.

So I replaced the main board, which has the HDMI and audio outputs, and STILL have an issue. Video is fine.

Hi @zzdodge,

Is there audio when playing a file containing audio from a USB drive inserted into the player?

Not sure if you meant all audio or not.

Here's an image of the audio troubleshooting flowchart from the service manual that may help.

Looks like the only other thing to check is the 3.3V power supply. I will look at that next. Thanks.
