We are experiencing a degraded picture on ITV3 when viewed though our Humax 9200T. Strangely, the picture on ITV3 is perfect when viewed on the TV's own channel. Both automatic and manual channel searches have been carried out, but things remain the same.
Our Humax is connected to the incoming signal via the antenna in port, and the TV via the loop out. Is there a rational explanation for this, please?
