Howdy Mike-d. here,
I do not know what a DMD is on a Mitsubishi 73'' TV.
I did do a little web searching and here is a couple of things I came across.

From this website: http://www.tvserviceparts.com/Mitsubishi_DMDChips.html WD73833 ALL 4719-001997 DMD Chip, DLP, 1920X1080/XHD5, 0.65"/ DC4, TYPE X NON
I have no ties to these websites.
"I researched this and it was a DMD chip that needed to be replaced."

Hope that helps.

I have the same issue with my 73". Rather then going over all of my connections and equipment I'll just say htat I feel your frustration. I have been on the phone with Mitsubishi directly and it appears as though they have a free software upgrade that should address this problem. If you call 1-800-332-2119 and press 4 in the menu you will get someone to help you. Be patient. They will make you go through all of the fixes that you have already tried. They will mail you a flash drive that goes right into the front USB port of your TV. I hope this is of help. Good luck.

This unit uses a DLP (digital light processor) chip and if this starts to fail then you will get spots appearing on the screen. The DLP chip will need to be replaced.
