Cyber blowing F1 fuse on power-up

Hello everyone.
I apologize for the length of this message.

I'm a nightclub DJ (Le Joinville to The Saint-Pierre and Miquelon, France), but I'm also in charge of maintenance of all fixtures.

I explain the situation: we have two Cyberlight CX but since several months, only one worked. We finally decided, my boss and I, to repair the second.

We have disassembled the Cyberlight from its support and completely disassembled the lamp compartment (transformator, power supply board, capacitor, ...) because we knew it was a power problem (no light, fan, or led).

Having established the integrity of the power cable and the proper functioning of the primary fuse (F1), I turned to the internal wiring and bingo: some cables, because of the lack of interviews (the time when I was not working yet in this club) were severely damaged.

To test, I plugged the power cable directly into the power supply board, bypassing the two safety switches (the wiring was faulty). I set the switch to ON and the Cyberlight finally came alive.

So I finally knew the reason for our problem. I then proceeded to change all the power wiring (main switch -> safety switch 1 -> safety switch 2 -> Power supply Board) by news cables.

I reassembled the Cyberlight and made news tests : all was OK. We ascended the Cyberlight on its support and made news tests again (with DMX). No problem. The Cyberlight has work with no problem friday and saturday.

But, late Saturday night, the Cyberlight stopped, no light, fan or led again. I reopened the Cyberlight to see that one of my news cables was moved and placed himself in front of the lamp: it was completely charred.

Having no new cable on hand (and wouldn't go down the Cyberlight again), I directly connected the power cable on the power supply board, like as I did in my first test (which had taken place, I remind you, with no problem). Cyberlight set to ON : no light, fan or led.

Audit of the primary fuse F1 : blown. I changed the fuse and restoring power : the new fuse has blown directly. Re-change the fuse (it was perhaps faulty) : another failure.

So, I have a Cyberlight that blow systematically all news primaries fuses F1.

I also recall that the safety switches (those which detects whether the Cyberlight is properly closed, so I think we can do without them ...) are no longer connected : the power cable is directly connected to the power supply board.

My question is : how to solve this problem? It's frustrating to see again this fixture off, when he worked two evenings only :(

Thank you
