Very glad Hans got his machine working again. Very cool that the collective minds helped get him there. I didn't know what to suggest, but for what it's worth i want to offer/share something else too. Recently my entire apartment/fairlight nest was filled, as i slept and was awakened to nausea, with the most noxious, toxic and disgusting odor imaginable - something like rotten eggs only worse. After opening all doors and such for ventilation and standing outside waiting for it to clear up i was able to sniff it down to one place: the 133 CPU board's battery(same part IIx and III). No leaking there luckily, but man it stank! It turns out when they go bad they can "breath" this gas out and seeing as how the Tadiran 1/6th D cell 3.6 volt TL 5135/P's (digikey.com and lots of places sell them) are all getting on in years (they're only supposed to last 10) though i'd mention this for the benefit of anyone whom hasn't already changed theirs to
get in there and do so (just know how to solder/desolder and don't the the battery get too hot or anywhere near water or moisture and dispose of properly) so they don't have to go through the stinky-room effect:) Seriously, you can change it after but why not pre-emptively change it first?
Best regards,
glenn

Hello again,
I'm glad to tell that my IIx is working again. Just like Joe
mentioned this was a power problem. I said that I checked all the
fuses. Well I checked them on the back of the mainframe. But after
opnening the mainframe I also noticed two on the board at the back of
the box. They were OK. And in the housing of the boards behind the
Frontpanel are also three fuses, and one of them -12V was broken.
After replacing it, the system booted up.
I want to thank all who did some co-thinking. Especially with these
old machines, where a lot of technical knowledge gets lost, we can
solve some problems by helping eachother.
