This just started happing When I turn the TV on.... It shows (my default input source) Directv-HDMI, or Antenna.... It displays the Picture/sound just fine for 7-12 seconds..... then the screen goes blank. You have to press the "home" button on the LG remote for the TV to return the picture/sound. This a new glitch, as it didn't happen for the 1st week I owned the TV Also what I have noticed is When I 1st turn on the TV and I try and press a button on the LG remote.... It displays "Please wait we are loading". It seems like when it is "done loading" that is when the screen goes blank. I realize not many people own this TV, but was wondering if anyone else was having this problem?
