After retuning my KD-65AG9 smart TV I have lost all HD channels and about 65% of the other standard definition channels are breaking up intermitantly. I have check the signal strength and signal quality and on average the strenght is 100% but the picture quality is between 33% and 38%. I did connect another HD TV set to the aerial output and that locked with no trouble to all the SD and HD channels that I should recieve, This Sony TV is not what I was expecting and over the years has caused maany irritating minor issues. Is the issue with the lost of HD channels and signal quality of the SD channels down to the TV aerial or the Sony TV? Amy help or suggestions on possibe cauase of loss of HD abd poor picture quality levels would be much appreciated.
