A Sure fire way to fix this is to see if your cable box has a HDMI output and your TV has a HDMI input. If they both do , get a HDMI cable to solve your resolution issues. A plus for this also is better signal quality than component cables. Also, the HDMI carries audio so no need for the RCA cables.
If your cable box does not have a HDMI- go to Comcast and trade it for on e that does. Should be free.

I assume you have cable. The cable HD and digital channels are usually sent in Quadrature Amplitude Modulation (QAM). The cable companies are required to send local channels in the clear but not so for any others. Regular (basic) channels may be clear or scrambled. USA many not be but HBO will be.
So you have 1 of 2 problems: (1) your TV does not do QAM or (2) they have scrambled the channels you want to see. Questions: (1) Have tried direct Over-the-Air (OTA, ATSC) reception for your locals? (2) Can you see the HD local channels on cable? (3) Are you paying for an HD box from the cable company to have the channels decoded? If in doubt contact the cable company.
Current Samsung TVs do do QAM and OTA HD. Alternatives are Dish or Direct to get satellite with an HD receiver using HDMI or 5-cable RCA. Costs are comparable but OTA wins, hands down. -Ken

o.k. check all your connections
if you have a newer house check to see if you have a main hub in a closet somewhere and check all connections. Check your hd receiver and you may be able to chage the DPI the receiver receives in.
I have this problem on some of my non HD channels, also. So much for going digital. I get fuzz and pixel problems "from time to time", but, if it is really bad and consistent your should call your service provider.
Things to ask also ? are you using cable or satellite.
If satellite T.V. there are other reasons you could be experiencing problems.
hope this helps!
