Welcome to Community@Insignia™!
For unusual color issues, the owner's manual recommends ensuring that your input source cable is connected securely and correctly. Picture distortion can also be caused by interference from appliances, motor vehicles and flourescent lights so a different location for the TV may be in order.
If you have any additional details about the conditions under which this problem developed, please feel free to reply to this message and I'll be happy to look into the situation further. You may also wish to consider service for your TV.
