Hi. I bought my first smart TV about a month ago and not happy at all with the quality of the SD channels but that is another topic. Today my few HD channels (I do not have a subscription / Sky box and connect with aerial) are even fewer by the loss of channels 106 to 115. Yesterday they were still there. Re-tuned this morning, but this did not solve the problem. So I have only 6 HD channels left on my new TV with a good to excellent picture quality. Can suggestions?
