I Get A Grainy Picture With Cable Hooked To My TV Using RF Cables.

Last Update Date : Apr 09. 2018

Improving Picture on TV

Checking the following may improve your picture:

IMPORTANT: When using a set-top-box you will only be able to recieve a 480i signal through the coax. For better picture quality you would need to switch to an HD set-top-box and the HDMI or Component connection.

• If you are using a direct cable or antenna connection make sure you are tuned to a digital station. (For example: Tune to 13-1 not 13)

• Replace the cable that connects the TV to the cable outlet.

• Check for breaks or damage to the cable, both indoors and out. If the cable is damaged, replace it.

• Check the center pin at the end of the cable you attach to your TV. Make sure it is straight and long enough to make a good connection.

• Make sure you are using the correct cable setting for your area. (For Example: Confirm if your signal type is STD, HRC, or IRC)

• If you use a set-top-box, make sure your TV is tuned to the proper station. Most often this is channel 3. Sometimes, it is channel 4.
