I purchased a Mitsubishi TV ws65813 at $5,000 4 year ago with 2 year of warranty. It doesn't work now because there is a problem with DM borad.  Two of my friends told me the same situation as mine before. After researching it online, I realized a lot of people who purchased the TV complain the same problem after 2-4 year of purchase.

I think the model of TV is in very bad quality and Mitsubishi doesn't want to deal with.

Don't purchase anything from Mitsubishi.........
