My TV, starting roughly last year (2020) but has continued into this year where the channels will pixelate and lose signal. I know it isn't the stations themselves because on my small antenna I use for recording on my computer, the stations show up fine. Anybody know what to possibly investigate so I can determine the cause, if it might be buying a new antenna altogether? There were no problems until recently, and they pixelate when there isn't any bad weather, or really any weather period. Any help would be greatly appreciated. Thanks!
