      Our Mitsubishi TV was bought in 2008 and it finally started giving us the white dots this month, Nov. 2017. Was able to find the right chip on Amazon and took about an hour to replace. Instructions were great, even though our TV was a bit different it was close enough. Great pics and instructions.

      Thanks for keeping this site up this long, still helping people.
