Hi Everyone. This is my first try so hope I'm in the right place! Bought the HT-X710 to match my LE40A686, speakers are not great on TV, and am very pleased with the result. Upscale DVD is great, sure it's not BlueRay but great picture, and audio is fantastic for my room. My problem is I feed my Sky via scart to the TV and have added an optic cable from TV to the 710. Audio from 710 is very flat but I don't seem to have access to audio control !! Switch to 'receiver on' on TV routes audio to 710 but can't access audio settings on TV or 710 so can't add any trebble and even vol does not display slider. Am I doing something wrong?
