Let me shar a few pictures. I have a trigger solution. That's also why I didn't want to build this myself. I assumed building with triggers would be too difficult for a complete novice like me.
It's board with the blue block where the lamp (the red one) goes off when it looses connection. As far as I can see, all the other lamps (also on the dlcp board) are still on.
If you can see from these pictures, the white standby supply connector (J17) on the dlcp board hasn't been used at all. I think he told me that everything was on another cable.
I don't know if that helps to understand what's going on here and what I can do.

😱😱😱😱😱😱😱
Do not use the device anymore!!!!!!!!!
The standby supply can only be connected at J17!!!!!!
It is connected at J16 now, that is an output pin to put a Hypex smps in standby!!!!!!!

Please don't panic, I think this setup uses the standby function for the power supply.
The standby supply can be connected to J4 pin 6 too.

Is it possible with the DLCP a real subtractive delay crossover according to Lipshitz and Vanderkooy (which yes if correctly implemented, no group delay distortion has) to create and if so how?
Everything is connected to J16. Pin 2, 3, 5 and 7 have been used. Nothing is connected to J4.

Pin 2 is the amp standby output. So there is no external standby voltage connected. Maybe the DLCP gets a voltage on this pin from the relay. Pin 2 is pulled up to the standby voltage when switched of. Maybe you can cut this wire to eliminate the problem?
Can you take a picture from the other side of the power supply?
Can't see a rectifier and regulator on the standby/trigger board.

No. Not the main switch. The lights on the board are still on.
Here's some pictures. Hope that helps. The trigger function works well by the way.
I'll most likely get some assitance tommorrow in the evening, but it's great if you see what's wrong and can share it. 🙂

Ok, the board with the blue transformer is a trigger board. Strangly I can not see a rectifier and voltage regulator on top. Maybe on the bottom side?
As I said before, disconnect the pin 2 wire to eliminate the problem.

Had a friend visting today. He went through the schematics and looked at the connections. He couldn't see anything wrong.
We then started playing and after 1 minute an half into the song it shut down, came on again etc. and continue doing that continually. However, seems like I was wrong about the ligths. The green light on the DLCP starts blinking and turns off as well.
Later when we tried playing something again, it worked fine and has since then. So it's not constant. We didn't figure out what the cause is.

If the green light starts blinking, de power supply drops below 15 volt and the system shuts down......
Could be that voltage drops, but this is a simple linear nonregulated supply and nothing indicated unstability. However he uses +/-15vdc, so it could be that it is just at the very limit and any minor voltage drop is sufficient to trigger the shutdown. The red LEDs on the board was constantly lighting, also when the dlcp shut down. When the D15 turned off it gave a short blink. Waiting a second and it turned on again. For a long period the dlcp toggled on/off with aproximately 2sec interval. After a while we should test other fault options and was unfortunately not able to get it unstable again. Spurious faults sucks

Is the transformer keeping up? It looks rather small.

It became unstable again later in the evening. Same thing, constantly going off and on.
A little drop in the mains supply can cause this. It is running below the spec's in the datasheet!
Good news, Hypex is going to design a dedicated power supply and a output board (with mute relays).
That's good. It takes time though both to design something and put it into production. Maybe ready for sale in summer time?
