If a DMD is otherwise bright and perfect in 95% of animations and runs a DMD test fine, can one rule out outgassing if only very specific animations are fading?
What I figured.That sounds like you have a data line problem rather than a degassing DMD. Have you tried reseating all the DMD feeder ribbon cables?
A good example is the high scores. High score 1 lights fine, 2 fine, 3 fine, 4 and 5 the initials are almost completely faded. I believe as it goes down the score board, the brightness of the initials decreases.Are the animations that are fading light more pixels then others? Have you got a video of the issue?

Oh it happens all over the place, but always in the same places. Certain elements of animations or whole animations are fading increasingly. Other animations appear absolutely fine.Doesn't look outgassed from that video IMO. Scores #4 and #5 just look blank (#4 does appear to have a small dot in it).
Have you tried a factory reset to see if that helps? Maybe non-volatile RAM has become corrupted.
Failing that, try another DMD and see if its the same.
I was just thinking to message you about sending a good DMD.
I assume all the test lights were fine, what tests showed the xpin wasn’t working correctly?
I just fitted one to Tommy and still have a solid lit DMD, a very different issue but worth knowing what good looks like.
That’s appalling, I’ve been recommending the xpins over rottendog, what have you replaced it with?Fixed. Brand new XPin wasn't outputting the right volts.
Got another powersupply and we good.
That is a shame as it does look a good bit of kit.
I tested the new xpin in mine and it was kicking out on pin 1 -118v and -102 on pin 2 from the HV to the DMD. Higher than expected and a drop of 16, same DMD results as when it was a drop of 14.3, fully lit. I think the HV is testing out as strong on this one.
I had an original board with a lot of ugly repairs on it which I didn't want to clean up. Bit the bullet and just tidied it up.That’s appalling, I’ve been recommending the xpins over rottendog, what have you replaced it with?
