I used a similar console to yours at a community theater way back when, and sadly don't remember much about its operation. However, as a basic two scene preset console (even with the recordable scenes) you wouldn't have any issues of dimmer profiles being set-up.
So, to trouble shoot:
1) Check your DMX run. Try unplugging the cable from the lighting console and then turning the dimmers on. If the dimmers don't glow as they have been, you know the issue is with the console. If they do glow, you know the issue lies somehow with the dimmers.
I don't know what else to suggest sadly. I had several dimmers die on me, and I had to replace the SCR internally, but whenever that happened the dimmer fails either full on or full off, not at a 25% glow.
Is it possible that when the electricians were running around they did something that somehow let some voltage trickle into your system? I'm not quite sure how someone would do that though........
The fact that you can get control of the fixtures above 25% when you need to makes it sound like there is some feature somewhere that keeps the lamp warm, and that somehow that feature got turned on. Check your console and dimmers for something along the lines of 'warm up' or 'preheat' or something like that.
Good luck, let us know what it is!

I did try it already when the dmx was removed, so I know that it has to be something in the dimmer (especially since when I walked in, everything was off) I can ask the electricians if I see them if they working with the dimmer system, but I kind of doubt that they were. And I'll look for warm up or preheat too...
Just so I know, also, is it possible that something can happen when we turn the dimmers back on (like them overheating if the fan hasn't been running or something)
