Re: Receiver Onkyo HT-R570 no sound .

Hello. I know this topic is a little too old but I have this same receiver and i think it has a problem in this ci (R2A1521RFP). It receives a analogic audio input from dvd or others inputs but nothing comes out. VCC is ok. I found it on aliexpress but before trying to replace it i'm trying to figure out if it is muted or not. It receives a signal from another CI (T5CN5, microcontroler) in pin 51. MUTE. Its a high level 3.3V signal. It becomes high when the receiver is turned on and stayed high all the time. I cant find the datasheet in inet...
