Questions and answers
I **** useing the av cables to my tv but no sound comes through
There may be several reasons why there is no sound from your Sony HCD-HDX285 when using AV cables to connect to your TV:
1. Incorrect Cable Connection – Ensure the AV cables are properly connected to the correct AUDIO OUT jacks on the home theater system and AUDIO IN jacks on the TV.
2. TV Input Selection – Make sure the TV is set to the correct input source that matches the AV connection.
3. Volume and Mute Settings – Check if the volume is turned up on both the home theater system and the TV, and ensure that mute is not enabled.
4. Speaker Connections – Verify that the speakers are properly connected to the home theater system.
5. Audio Output Settings – Ensure the home theater system is set to output audio through the AV cables and not HDMI or other digital outputs.
6. Defective Cables – Try using a different set of AV cables to rule out any cable issues.
7. System Reset – If none of the above steps work, reset the home theater system to factory settings and try again.
If the problem persists, the issue might be with the internal components of the home theater system.
