I have a 42LG30, and am interested in how to update the firmware. Lately, it has been losing signals for over the air (antenna) broadcasts. I imagine over the past 2 years I have owned this, it has been updated. Does anybody know how one goes about updating this firmware?
Check at your TV manufacture's website under support to see if there is an update for your model and serial number.
Your signal degradation is probably due to an antenna signalblocking problem or due to the cable connections for your antenna becoming corrouded.
