I have a stupid question. I recently purchased a new Wega 27" tv and I've noticed that the picture quality on the local channels aren't as clear channels such as HBO or MTV. The picture quality changes from day to day. There are times when the picture is pixelized, the brightness and color tone would change slightly and the sound would sometimes cut out for a brief second. Sometimes the sound would cut out 5-10 times a day. I only notice this when I'm watching local channels. When watching dvds, the picture and sound is fine. I have the RCA directv receiver hookup up with a coaxial cable to the vcr, and vcr to the tv. I tried connecting the satellite to my receiver but the sound still cuts out for a brief second sometimes. The picture quality is better when I connect it using a s video cable to the receiver but the brightness and color tone still changes. Has anyone experienced this? Is there something wrong with my tv, satellite receiver, or is it just the directv signal? I'm just worried that it might be the tv and that if I wait too long I won't be able to exchange it. Please help. Thanks.
