Quick question on this type of driver boards, aside not having any waveforms (aside audio on pin 1) on any of the pins of the driver board, is there any other checks to determine if the driver board is dead?
thus far:
> I've read through numerous threads, I found some "good" voltages for reference in this thread ( https://www.diyaudio.com/forums/car-audio/286461-soundstream-xxx6500-sound.html ),
I have all those voltages but no R-R oscillation, all referenced to pin 2 on the driver board.
>I have a strong 45hz entering the board, I have audio on pin 9 of the DLI4060B,
>I don't have any any waveforms on any of the other pins on the other chips on the driver board.

Do those terminals connect to any header pins of the driver board?
If not, follow them back to see if you can find their power source.
