I've got a two-year old Panasonic DVD recorder and while I've been really happy with it, all of a sudden something deeply irritating has been happening with it. I put a disc in hit, 'play' and there's no sound. This can go on for ages (ie, with different discs, pre-recorded or home-recorded, and after pulling the power out, effectively rebooting it). So far, it's always started working again, but presently it's completely random whether I'll have any sound or not. Is this a common fault? Any other users experienced anything similar? Do you think it can be fixed?
