It's a Leprecon LP 1500. It's old. For the past six years I only could use channels 1-12 and just last week learned how to get channels 13-24 to work. Slider/Channel 3 has never work, which is odd. Within a half hour, my lights went from working to not all working. I don't have lights hooked up to every channel, but these are the channels that did work at the beginning of my rehearsal. 1, 2, 4,5,6,7,8,9,10,11,12,15,19,22,23,24 then, after a student was trying to record presets channels 1,2,4,7,8,10, &19 wont work. There is no reasonable explanation to this that I can think of. The bulbs did not blow, the cables did not get moved. It has to be something the kid did to the board.
I was trying a few things. I used the erase all button, which I believe is like a factory reset, but it didn't work. I did go to record a preset with channel 4 and the lights came back on, but then a few minutes later after moving the sliders up and down a few times, they went back out.

I would suggest a "hard reboot" to your board. Without knowing the specific brand, most boards have a feature that restores all to factory presets... it could be possible that there are some errors in the patch, etc. I would try that as the next step and go from there.
The other question that comes to mind right away, is-- are the dimmer packs "daisy chained" together with short DMX cables-- one could be bad or loose, etc. Sometimes, a cold solder joint will fail, but not completely, resulting in DMX errors.

This past weekend I had rearranged some lights on my light board. To be more specific I replaced some bulbs and hung some new lights and rearranged the plugs into my dimmer boxes. Today I showed my students the new lighting arrangement and went through all the channels (24) and they all worked. Later on while I was not in the light booth I had a student trying to record presets and after he had done that I realized that some of our lights were no longer working. And I don't know why.
Now I know that channels 1 through 6 are on dimmer box 1 and channel 7 through 12 are on dimmer box 2 and so on. It would make sense to me if all the lights on one dimmer box stopped working but that is not what happened. I have random channels that don't work all of a sudden. The lights did not blow out. Channel one for instance no longer works so I went up into the loft and took the plug to that light and tried it in a different channel and the light turned on so I put it back. I checked all the breakers to see if anything changed and nothing changed... everything was on. I shut everything off and turn it back on again to see if that would work. That did not work. I then went to the board and took out my manual and I erased all the presets to see if somehow that would bring the top channels back, but it didn't. I looked at all the buttons and knobs to see if they had touch some other buttons but as far as I can tell, they didn't and they nor I have any idea what they did. I checked the patches on the board, which I'm new to. I just learned it in the manual today, so maybe I did it wrong? It looks like dimmer one is on channel 1 and number 2 is on channel 2 and dimmer 3 is on channel 3 and so on up to 24. I am at such a loss right now that I want to cry. I just had my stage nearly lit up perfectly for the first time in 6 years and all of a sudden 6 channels don't work, which is about half my stage in no particular pattern. I don't know what to check next and I'm not great at the terminology but please can someone tell me something else to check.
