         Subject: General troubleshooting for Protect problem.




    Use scope to check at power on before unit go protection -->




    Replace all driver transistors at the def.channel at the same time -->

HTR520,TXSR502..
  Dsp board no audio signal output
1 . Normal audio using analog inputs. Do you have all Dolby surround sound ?

2 . All DSP voltages are normal ? Did all supply voltage go to all ICs ?+5vDSP, 2.5V,+3.3V...
+7v,-7V..
3 .Input sel IC. Use CD analog input audio signal (ADRT+,ADRT- and ADLT+,ADLT-) out to DAC IC ?
    Surround analog signal out (DAC L,DAC R,DAC C,DAC SW,DAC LS, DAC RS ,DAC SB* back to Input sel.IC.
    Pin 1 to pin8 out to p5504. ( Same as pre out) check Mutting transistors Q5600
    to Q5617 .
4 . When use digital input signal did digital light up on display ?
    If missing 3.3v,2.5v 5vdsp (on Reg IC Q5640) to DSP ICs will disable DSP function. (U05 Amplifer PC board)

  Please use TX-SR502 as sample Technical Tip Troubleshooting.


When you need Tech help Please use Tech Email and give us Voltage and signal info. What voltage on DSP ICs
and whereyou lost audio signal ? What you have on input IC Data line
Check with TX-SR502 Troubleshooting tips for the Microprocessor and Audio Select IC


Pop noise in speakers Check next page info you have DC in audio line at any channel .
