Question: How to open the hood on a Durst Colidap 1205 to inspect the wires and fan

[Stigmw]

I have a Durst 1200 with a Colidap 1205 colour head.
The power went out on it when it overheated during a very long exposure (25 minutes). And instead of the fuse or the bulb blowing it seems maybe the power wires maybe melted or came loose.
So I want to inspect the inside, but can not remove the metal casing hood on the top.
There are 6 small screws that seem to hold it in place, but taking them off the hood still is hard in place, almost as if it is glued or welded shut.
Any advice if there are secret screws or this is the wrong way of opening it up?

And could it be the power supply that is meltet inside, all the wires there look fine.

Thanks for the tip!
But I have already checked the manual, and it doesn´t really say how the hood is fastened, apart from the obvious "release the screws". Which I have done, but the hood is still stuck.
Other advice so far is that there might be hidden screws on the inside. And, yes that might be true, but I can´t see any inside and hope someone else have opened one up before and knows if there are or not.
