I know those modules. That are 2x 473nm dpss blues of 1W each combined. Marvelous colours.
But he drivers suck. Probable one of the drivers broke. How many sub-d connectors are there on the dual blue?
Usually there are 2. If so you can switch the sub d's and see if the other laser starts to lase.
If that is the case, then it might be one of the power supplies that is gone.
These projectors usually have 2 power supplies per head. And I found them to brake from time to time. (assuming the power supplies are those open frame power supplies)
