Okay I have a 20" Magnovox smartseries tv which has no sound. I have pushed every button and unplugged it but I can not get sound. I thought my kids blew the speakers (its very very faint turned all the way up) and was going to call it a day when low and behold my nephews hocked up a nintendo and-- perfect sound. It is not muted, oh I also moved another tv in there to check if it was cable and that tv had perfect sound. Heres the kicker- I just called Magnavox and they want $10.00 to offer technical support over the phone- HAHA!! I'd sooner get a new tv.
