Default new tv fuzzy/wavy reception on most cable channels

hello. im new here. so please forgive me if this question has been answered a million times. i recently bought a new rca 32" lcd hdtv. i hooked it up to my comcast cable box and all the basic channels (2 through 80) have a wavy mildly fuzzy picture. the high channels like all my movie stations come in perfectly fine. what could be the problem? my cable box does not have any hd hook ups as in dvi or hdmi or anything like that. it just has either coaxel or av cables. and the av's are just the basic red, yellow, white. so i have no way of testing any other connections. my old tv worked perfectly fine using this exact cable box and connections. i thought it may be a defective tv bought if that was the case why whould all my higher channels come in so clear? i have tried other channels like channel 4, 3 and all the video or hdmi channels but it seems to do the same thing no matter what channel im on, and all my connections are plugged in fine. i hope this is a easy problem to fix. what am i missing or doing wrong?

Well i switched to a hd cable box. And the problem is still there. I have it hooked to a hdmi connection. And now all my stations are sort of wavy and fuzzy. What am i missing here? I dont think its my tv because i have it hooked to my xboz and it looks great. Is there any setting or cable im not using? I dont know much about this stuff so any suggestions whould be appreciated thanks.

Can you post all of your equipment, and how everything is connected? Like this:

Sharp LC37D43U
Onkyo TX-SR605
SciAtl 4250HDC

SciAtl -> Onkyo via HDMI
Onkyo -> Sharp via HDMI

Also, have you talked to the cable company and your TV manufacturer yet?
