Good day, all. I have recently (2 weeks) got a new 50" DLP RCA Scenium HD50LPW164. I am getting my digital cable and High Def from my cable carrier. The set top box is from Scientific Atlanta. When I hooked everything up and began enjoying my new set, I noticed an intermittent popping or a crackling sound coming from the TV's right speaker. I then ran the sound directly through my reciver and turned the sound off in the TV. The problem has been "ignored" this way. I know I made the proper connections, and I used Moster Cable. Rather than simply by-passing the problem, should I get someone from the store to check this out. Or is running sound the way I have it now best anyway?
