From 2 month, I put my Sony Tv to receive signal from sattelite emission. Was OK. From one week go, I have on my TV display random pictuire & sound major distortions during period on time started to 2 minute until 35 minute. After this period of time (when I only wait), this majors distortions pictures & sound just go away, without any personal actions.During this time, pictures on my second TV conected to the same satelite signal is perfect. Do you are able to give me an idea, why I have this major distorsions (for all chanells is the same problem) only my SONY TV - set?
