Question about Sony FD Trinitron WEGA KV-27FS120 27" TV
Take a look at the back of the set. Some Sony models have a speaker on/off switch, and they can get bumped if anybody's been behind the set (cleaning or such, and sometimes a pet can get back there and bump the switch). Also, check that the TV hasn't has the SAP (second audio channel) turned on. On many Sony remotes there is a single button to select that mode, and if there isn't a SAP channel being broadcast, on many models you get no sound at all.
If you're using a satellite receiver or cable or FIOS set-top box, make sure the volume is up on that device. They often have volume control separate from the TV, and you may have turned the source volume down.
You didn't give any information about what you have connected and whether the sound trouble is on all sources, so I can't tell you too much more. Make sure all your cables are properly connected (they sometimes work loose) and all audio sources are working properly. If the sound still is missing after you've checked what I suggest, you should to have the TV checked by a service technician. There are many possible electronic causes for the sound to quit, but nothing you'll be able to track down and repair without the proper tools, information and experience.
Good luck, and thanks for using Fixya!
