I am using a Sony TA-E9000ES and a Sony TA-N9000ES and other mostly Sony audio and video sources. My problem is that I can’t view the video sources on my LG 49UF6430 Tv even though I can hear their sounds on the speakers and, I can’t hear the Tv audio through my speaker system. I used optical cable for the Tv-preamplifier connect. I noticed that LG Tv brands are not on the list of Tvs preprogrammed for the Sony preamplifier. Aii suggestions will be appreciated. BTW, I am a newbie. Thanks.
