Catherine Posted July 6, 2021 Share Posted July 6, 2021 I have a GP-510, 8 months old. On switching on today, no output through speakers, headphones OK. Have worked my way through toubleshooting, no luck. Speakers are totally quiet, no humor buzz. Any ideas? Thanks Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted July 6, 2021 Share Posted July 6, 2021 Looks like the troubleshooting chart in the manual covers everything you can try. Perhaps the headphone jack is not switching back to speakers properly. Have you tried inserting headphones more than once? Does a visual inspection of the jack show anything foreign possibly lodged in there? Quote Link to comment Share on other sites More sharing options...
Mike Martin Posted July 7, 2021 Share Posted July 7, 2021 Insert and then remove headphones from both headphone jacks. There is a physical switch that turns off the speakers when headphones are connected. Possible that something is stuck there. Quote Link to comment Share on other sites More sharing options...
