I would check your cable ends for good termination connections.
On my 295RL I have found 6 bad cable connections and fixed them all. They use these twist on connectors but whomever is installing them at the factory does not know what they are doing. I have not noticed the problem that everyone is talking about but I have not been paying attention as I have only been watching movies because the reception has been so poor. We will see in the spring if it has made a difference.
