Guys, I'm havin some major trouble, and wanted to know if there was SOMETHING I could do before I get a repair guy over. My lg 37lc2d TV was working just fine until I come home from work a few days ago. After 9 months, the TV suddenly stopped displaying a picture. I could hear the sound from the cable box just fine, but ABSOLUTELY no picture whatsoever. No channel indicators, no source indicators (like video1, hdmi, svideo, etc). It doesn't even attempt to display anything. I've tried simple things like unplugging the set for awhile and resetting the power of both the tv and cable box to no avail. I see no factory default switch to try and that's about the extend of my tv tech knowledge. I was HOPING somebody here would have a solution. Any help?
