Why is the picture quality good on some channels and poor on others on my Insignia NS-42E470A13?

If you're experiencing good picture quality on some channels but poor quality on others with your Insignia LED TV, the issue may be due to a weak signal from the broadcaster or cable TV provider. If you are connected to cable or satellite TV without a set-top box, installing one might improve the picture quality.
