Ive got a blue spot on the lower right hand corner of the screen. what is this?

Go to zenith.com, look under the service icon at the top and then you should see a listing for "Class Action Lawsuit/Settlement". If you follow that link, they'll have specifics listed for this suit that was brought against them (including tv model #s included in the suit). There was an agreement reached to fix/replace affected t.v.s, court date was in Feb. I believe, and just waiting now until they post information on how to proceed.
