If you are running normal rca (red, yellow, white) for your reception try fiddling with the yellow one. this is your video feed. If they are component cables (red, blue, green, red, white) make sure that the reds arent mixed up and if its and hdmi cable it may just be faulty. Try replacing it. hope this helps
