My TAF has a nice strong DMD. The other day, I turned it on and it was barely readable (the center area was out and it was looking like smoke). The data was fine, and the text/graphics were fine, just not being displayed (like the DMD was gassing out). I switched DMD's and its the same. Reconnected everything on the boards and such, still no difference (everything is now out 100%). Is it safe to say this is a DMD board issue? If I was to switch over to ColorDMD, does that bypass the board and would solve the problem (I planned on getting one for Addams eventually)?

Thanks!

Take the DMD driver board out of your Jackbot, Flintstones or Theater and put it in your Addams and see if it works with the DMD. My guess is the DMD driver board's HV section (bottom 1/4 of the board) is toast. You can repair the board for $6 but there are about 25 things that get replaced. Traces usually need to be repaired as the heat typically destroys them.

You can buy HV piggyback boards ($60ish) or replace the entire board with a new aftermarket ($100ish) if you are inclined to go that route.

What are the voltage readouts of the female connector going to and providing power to your DMD?

yup I bet its the highpower section , the piggy back boards are cool and super easy to install if you are not comfortable doing board work or as simple as it is it could be bad ribbon cables.

I'll try swapping out another board...didn't even cross my mind to try it (Flintstones will be the victim)
