I have an RCA rear Projection TV model # p60812BL manufactured in 1998, no sound is coming from the tv when watching cable TV via a digital box. When the mute button is pressed and unpressed you can hear the sound clicking on and off and same thing when turning the volume up and down but nothing comes out when watching cable tv. However when the game console connected via AV jacks is played the sound is perfect. Please help

It depends on how you have the box hooked to the tv, is it via cable (co-ax) connection or rca (red yellow white) cables ? You may have the audio hooked wrong or it may be a blown input in which case switch to a new input on the back of the tv (possibly the one you used for game systems). If ur using a co-ax connection from the box try rca cables and if ur using rca try co-ax. If none of this helps call ur cable provider and tell them the box doesn't have any audio and u know it's not ur tv. Usually they will come fix it 4 free and try n educate you to what went wrong.

Tries tv and cable box unplug,replug it back like about an hour.For the tv resetting itself and the cable box to upgraded it softwares.Go into the tv menu go to Audio SETUP.Go down to audio ressetting,these steps should solved ur problems,but not call ur cable companny replaced the reciever box,it have problems.
