What could be causing my tv picture to be grainy on an hdtv?

Often times when this happens, It is the result of a contact cable being connected wrong. Check all connections are secure, and take off cables and reattach them. Make sure cables are in the right place. Refer to your TV's user guide for assistance.

You may not have the correct HD cable. Even if you have an HDTV, you wan't get HD quality if you don't have an HD cable. Go to any electronics store and buy an HD cable and your problem should be solved.

You could be looking at a standard definition signal such as a DVD player or cable station. If your watching cable or satellite, it could be that your TV signal is being over-compressed. You may also just be sitting to close to the T.V.

There are a number of things that could be causing a grainy picture. A faulty cable between sources. Low resolution or standard definition cable will not be true HDTV, and thus grainy because the TV is trying to create a big image from a small one.
