Question about Audio Players & Recorders
I have a Onkyo TH-SR502 amp which was working fine until suddenly no sound were coming from any of the output connectors (including the phono jack). I got it checked by a audio repair specialist and he informed me that the DSPB (Digital Sound Processor board?) has busted. The code printed on this board is MCDG-8230/CMKM-P3X.
Is this diagnosis correct? Or is there any known solutions that you know of that I can tell my repairmen to try.
In case the solutions is to replace this board, can you tell me how/where i can get one of these please.
Thanks in advance.
Before doing anything drastic I would suggest a visual inspection for cold / open solder joins around the knob and surrounding components. I would also try to clean the knob with some switch or contact cleaner.
If it passes all above and still have the problem I would replace the volume control.
But if jiggle clears it then its definitely a bad connection somewhere or a bad / dirty volume control

Field inspection is more accurate than on line and it depends on the personal of the service spechialist.and from here i can not make fair judgement.
