Hi folks, new to the forum - I have an Onkyo CS-245, got it for my daughter for her room - Everything works, CD, USB, Radio, Line, Speakers etc - Headphone jack working etc. No sound from the unit itself. It was spluttering intermittent sound but now completely no sound. Its been treated very well and not knocked at all. Should I bin it - its one of those things that's bugging me so much - I know its cheap, its not knowing what's wrong that's bugging me.
