try to troubleshoot it... 1. Check the volume/mute button. 2. Check the channel. 3. Check your wiring..if ur using rca's then possibly check the white one and see if they are all plugged in properly. 4. What bin are u using and how long have u had this problem? Did it jus happen? You have to supply more information to get better detailed answers. 5. Good Luck
another thing you may check is that if you have selected a different language on the audio selector, there is a button on your remote, the one to the left of the EPG, press it and get sure you select the "eng", that is for each channel you may have the problem
