Hmm, did not think of that one! Well, problem solved!

Puuh. Only the battery of the Remote was down and the system works correctly. What a joke.

I was happy. yesterday because I found a broken pin in one of the connectors. Everything worked fine. Then I got call from my whife this morning - doesnt work again. Back to start.

Thanks so far. Have to make some days break on this issue due to travelling now. I´ll come back later.

The NTC is placed on a very small PCB which is screwed to the heatsink.

I built some tube amps by myself so I know how to solder and basics about reading schematics. Unfortunately I have no schemytic for the convertor. How do I find the NTC?

I don't know how technical you are. You could simply disconnect the NTC, if the amplifier switches on after that it must be the NTC. Maybe another way of checking, does the ML/MCL converter switch on very briefly (led turns green and red directly after that) if you choose a source in a linkroom? And is the red led on on the IR transceiver in the linkroom?

I have to wait another day because the shops where I could get the cable rsp. plugs are closed on monday. Does it make sense to check the NTC separately?

Connect the powerlinksocket of your Ouverture to the powerlinksocket of your ML/MCL converter. Switch on the Ouverture and see if the converter also switches on. Reason for this test is that there is an NTC in the ML/MCL converter which switches the amplifier off when it is overheating. This NTC sometimes changes its value because of age. Because of this the safetycircuit thinks it is overheating and switches the amplifier off immediately. Another way of testing is connecting an ML IR-eye (round aluminium eye) to the converter and see if this will work. But for that you need the IR-eye.

How would that go? I think I can make me such a cable, latest by tomorrow.

There might be another way to test the amplifier of the ML/MCL converter, but for that you need a fully wired powerlinkcable.

If there is no alternative I would go for that. Unfortunately all the cables are fit together now and it will be a bigger effort to separate them ....

I will continue on that by tomorrow. Thanks a lot for your help so far.

Cheers

The test with the LED only works for an MCL2P. Is it possible for you to connect just one MCL unit at a time to see what happens?

Re: MCL/Masterlink System ausgefallen

wolferich — Sat, 11 Feb 2012 15:19:29 GMT

Ooops. Its an MCMXCV ML/MCL converter(but its also an amplifier, isn't it). I Thought from photos that it was an MCL2P. I am really sorry for that misinformation.

Took the cables two three pole connectors out, power up the Ouverture and nothing happened. the LED stayed red.

Does that indicate that its either the masterlink connection or the MCMXCV?

If it was a masterlink cable you woeld not have an MCL2P but an ML/MCL converter. But the cable from the Ouverture to the MCL2P has an 8-pole connector on both sides? In that case disconnect the two 3-pole connectors from the MCL2P and switch on the Ouverture and let me know what happens to the LED on the MCL2P. If it goes to green shortly and right after that to red I might know what could be wrong.
