Pr603 no sound out of speakers.


Hi everyone!

my sx-pr603 works very well using headphones. But when pull out the headphones jack, there’s nothing from speakers. Anyone can help with this situation? I tried to disconnect the connections between  headphones jack and the AS PCB, but nothing changed.


thank you guys

    Hi, I realise this is a bit late in relation to your original post but as no-one else seems to have replied, here is my suggestion.

    It’s possible that when you unplug your headphones, the jack socket connections which disconnect the speakers are not making contact.  You could try spraying contact cleaner into the socket but if this doesn’t help, you may need to open up the case to access it and clean the contacts manually, assuming it’s not a sealed, board-mounted jack.   If it is, and you have the use of a multimeter, you could measure resistance across the contacts with the headphones plugged in then removed.  There should be a difference in the readings but if there is no resistance with the plug removed, that would indicate that the socket is faulty.

    I hope this is of some help.
