MITSUBISHI WS-65613 Blinking Light, won't come on

My Mitsubishi WS-65613 TV is only about 5 years old.  I'm experiencing the issue green blinking light and now it won't come on.  I've read on this forum about the same problem being a bad DM board and needing the capacitors changed.  Someone, please send me the instructions to replace capacitors in this model.  Also, where is the best place to purchase them? THANKS!  Springer
