I just received my 337H on Wednesday, so far I'm loving it, great picture, I don't even mind the OSD. However, I can't get the audio from my digital cable box to play through the TV speakers. The cable box is hooked up through the S-video port, with an A/V cable for audio. I also have a VCR plugged into the composite port, with it's audio run into my HT receiver. I know the speakers on the TV work, because I can get audio from my DVD player which is plugged into the HDMI port, and I know my cable box is outputting audio because I have it plugged directly into my HT receiver as well, through it's digital coaxial output. Has anyone else encountered this, or have any ideas? Or do I have a defective TV? Thanks in advance.
