I have an LG Plasma TV and for the past four months I have had a problem with colored "snow" flickering over the picture on my TV.
Here are a couple pictures I managed to take of the problem:
I don't think it's cord related because it happens when I am watching cable via component cables and a DVD through HDMI.
Any ideas on what could be wrong if it is the unit itself? I just passed the one year mark with the TV last month and like I've said this has been happening for quite some time, so I'm hoping something didn't fail on me already.
