SOURCE: sony bravia intermittent sound
Yep, same problem with mine. After many trial fixes, I discovered that it's the HDMI connection. I tried two different new HDMI cables in two of HDMI ports on the TV, but still got intermittent sound. The only way I solved it was going to component cables (RGB) with a separate audio cable. Works great now. Other Web sites say that HDMI connections do not always electronically "handshake" well between devices. Not sure how this HDMI problem can be permanently fixed, but using the component connection works fine.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Check the connections between the cable box and the TV. If you are using scart check the connector is in squarely if using rgb or composite you need a separate audio connection using the red and white phon sockets.
