The man who helped me at LG today had me do something that is "supposed" to help when the live TV isn't functioning. I can't really test it as the darn thing is working perfect at the moment LOL I had not hooked up the BluRay on this 2nd set. I did as little as possible since I figured it was leaving soon anyway. So he had me take the cable box HDMI from #1 to #2 and put the BluRay HDMI in #1. He said you always need to see if the TV works with the other components. OK - whatever - maybe it is the cable box but I don't believe it!! Anyway if the live TV problem happens then I am to turn off the TV, turn on the BluRay then turn on the TV, change the input to the BluRay before trying the live TV again. Kinda of crazy to me but then what do I know? So, I'm going to hang in there & play with this a little more before I give up on it. Even though it's making me crazy!!
