I have checked signal strength and quality on several channels and I get 89% to 95% for Strength, the best is BBC the lowest was ITV Channel 10, ITV3.
100% for quality.
One possibility is that your signal strength is too high. If there is any amplification in your aerial system then try turning it down or removing it; alternatively fit a variable attenuator to the aerial feed. We had a similar problem with an HDR-2000T which was resolved by fitting a variable attenuator and reducing the reported signal strength below 80%.
