Why is picture quality good on some channels and poor on others on Insignia LED TV?
- J
  Jacob MccormickAug 25, 2025
  If your Insignia LED TV picture quality is good on some channels but poor on others and the sound is good, the problem may be a weak signal from the broadcaster or cable TV provider. If you connect to cable without a set-top box, you may need to install a set-top box to improve the signal reception and picture quality. Contact your cable TV provider about upgrading to a set-top box.
