Question about Home Theater Systems
I think you've answered your own question, circuit power is not going from one side of the DSP chip to the other and that suggests that the DSP's core is at-least partly DOA. You are indeed correct that functional power should be at 3.3V and yes 0.3V does make a difference to the components that rely on a 3.3V feed, however if the DSP is fried you are not going to see normal functionality or be able to diagnose further.

My receiver is experiencing the same issue now. I was thinking it was an amplifier output stage going out. I only took the hood off and measured some typical voltage areas, nothing too in depth while on the living room floor. What was your conclusion? I'd much rather fix mine than buy a new one.

Try a factory reset[don't ask me how].Your processor stopped working properly...
Ask on producer's site for help and support.
Maybe you need to flash it.....
