I bought a brand new Denon AV1803 less than a week ago. Today, while I was watching Private Ryan on my Pioneer DVD, suddenly the amplifier only produces strange noises similiar to hundreds of birds chipping. I was shocked and rushed to turn down the volume and stopped my DVD player. Quickly after that, I turn off both devices. When i turn them on again, there is no sound via any digital signal (coaxial or optical). The amp knows that digital signal is present (LCD display shows digital) but it refuses to turn on Dolby Digital or DTS and I don't hear any sound. I tried to select dts but still no sound and either DD or DTS will lights up. I've tried the AUX input and it's dead silent as well. However, Analog signal works fine (composite). I have reset the whole system (as described in the manual) but the problem remains. Is there any other way I can try to fix my brand new Denon AV1803? I have only had it for 5 days!!!!!! Please help!!!!
