I can get to the web with no problem on my LG TV ( Model UM7300AUE), but when I try to watch a live stream event, I just get a blank screen. Our church live streams services from their website. On my computer, it launches automatically. From the tv, I can get to the exact same page, but no stream, no error message. I chatted with someone from LG, who told me the tv's browser is incapable of watching a live stream and that I can't use another browser. I know other tv brands (even older models) do this with no problem. Can anyone help? Thanks, Johnny
