I've just unpacked and setup a brand spanking new Panasonic SC-HT900 and the bloody thing won't work.... I've loaded a disc but this unit has a five disc changer and the disc tray just spins around displaying "Waiting". I can't get any on-screen displays up, can't change to Tuner or Audio CD. I've powered up/down, pulled the plug out, pressed all the buttons on the remote and the unit itself - everything I can think of. Am I missing something blindingly obvious???? The instructions don't indicate any specific start-up routine and the tuner WAS working...... BTW:I've also posted this on the DVD Player forum...I'm suffering from tech-rage at the mo, please help an unstable mind...!
