Hi, I bought LG 47LB678V this week. I have got really problem find something about model 678V I believe that a design is only one difference between others 67-V models. Anyway, tv recieved only update to firmware version 04.32.20 from last October. I found on LG website for TV 679V latest firmware 04.45.04. My question is, can I download and install this firmware to my TV? I have really big problem with "out of memory" error. Thanks
