Tried my iPod on it and it worked perfectly. Tried to hookup the TV w/ the same cord out as from the iPod, again no sound. Got a different set of RCA cables that I know were working as recently as earlier this month, again no sound. There is no troubleshooting section in the manual, you are referred to the website FAQ's where there is absolutely no info. on this or any other audio models there either. Any suggestions.
