Part Number:PCM1681
I got Onkyo htr558b has digital output problem, when I start it after a day I get every sourse playing sound, after 5 to 15 minute the problem is that it has no sound in dsp mode, in direct mode i am getting sound without digital source, when i am playing file from usb or any other digital source i am not geting sound in even direct mode also, so i open and investigate where is the problem, i checked the dac chip when i am touching on DAC chip (PCM1681) i am geting distorted sound, then i checked digital input pins with oscilloscope I found frequency on 6,11,12 pin. also i found just now when i am touching (not the pin only top black part of the ic) the pcm1681 i am getting distorted audio also sometimes clear sound for few seconds. I found someone online who has same problem then he change ic and his problem solve. In my case if I order the ic I will get it after 40 to 60 day and It cost me too much,
Any way other way to fix this? Help pls
