Hi folks,

Have one where on channel change the sound vanishes. It doesn't mute as OSG shows it should be there.

On turning the set off and on again sound is OK on any pre-selected channel.

Tried Factory reset but problem remains. Curiously if channel is changed one step at a time, sound is OK - Odd one - Any thoughts ? - Chris.
