Several months ago problems in tuning and in HD started on my FoxTR. Firstly, my TV started coming up "Incompatible signal" from the Humax box, whereafter it tuned to the signal but only in SD, not HD. there is no problem with the TV (a Pioneer KRL46V) receiving HD from a chromecast, so that is not the issue, and the signal strength is OK (strength 75% quality 100%). I also have some pixelation, despite that signal strength, which do not occur with my TV. I am monitoring that issue, since I improved the signal by shortening the aerial input path.
Any ideas?
