Samsung HL S 5679 56" DLP TV purchased late 2007, installed 2008. Failed January 2009--capacitors replaced. Failed November 2009--DMD board replaced. Has failed again September 2010--LED lights flash, sound comes on but no picture. Cost of TV + repairs so far = $2278. I know this is a lemon, but what to do? Doesn't make sense to repair again....Advice?
