You tried going though the diagnostic options and see if that picks any thing up ?.

I would check the front panel for dry joints, would all so check if analog and digital are effected though different rear ports too.

I cannot really help you but thought i would try at least.

Re: Yamaha RX-V675, No sound

DSP/DTS IC has failed many times in Onkyo, Harman etc maybe the case here.

Yes that would not surprise me, seems to be a common issue with AV HDMI devices and typically due to heat.


In some cases people have heated up the DTS chip to get it working, replacing it will not be any fun at all.

DTS chip number is D80YK113CPTP4 . is this ic also premature failing as in onkyo?

Re: Yamaha RX-V675, No sound

Would like to revive this topic.

Currently working on my Yamaha RX-V673 which also has infamous D80YK113CPTP4 DSP IC. When PCBA is bent or small portion of heat applied (e.g. hot air) to the IC, DSP is OK (viewing via Service Mode, C category, DSP1 BUS: OK/NG) and NG when cooled.

Has anyone tried replacing to a new D revision chip from aliexpress? Not quite sure whether DSP IC is bad itself or cracks in tracks/vias.

I had a problem when loading firmware had error 0010, heated the chip firmware installed OK but when chip cooled no sound.
I was thinking of changing DSP IC don't know if it has to be pre programmed.
