I've been listening to my beocenter for over a week now (with sonab od-11 speakers, which I bought last week). I've also used quite high volymes, trying to provoke the fault switch, but Beocenter hasn't turned off. Thanks for your help! There are stil some minor issues I need to fix: the plastic part of the turntable lid came off, the hinges

[quote user="tournedos"] That should be far enough off to cause problems, I believe it will work normally now after adjustments. Those trimmers didn't move by themselves though, so they are bad - replace them, or the setting might not stay for long. [/quote] Will do. I didn't see any visual damage in the capasitors, and there is nothing

It isn't the remote control, that's one of the first things I thought and tested. I opened the beocenter and tested the no load current. It was 36 mV in TP200-201 and 40 mV in TP100-101. (...yes, I found the service manual...) I adjusted the trimmers so that the no load current was 10 mV and after that I was able turn up the volume without beocenter

The humming stopped when I turned to 240 volts. I noticed that beocenter turns off even while playing radio if I turn the volume up high enough...

Ok, I guess recapping would do good, even if it wasn't a leaking capacitor causing it to turn off. And replacing the old trimmers at the same time might be a good idea. I have done some soldering before: battery powered small amps and guitar effects as a hobby, but I haven't worked with high voltage devices before... Is there lethal voltages

Good point... I haven't touched the timers at all yet, but i can check them tonight. Last tuesday my 7700 turned off five or six times while playing, so I'd suspect it's not the timer... Juho

I noticed that there is also an audible quiet humm from my 7700 whenever its power cord is plugged in the wall socket, even when the power is switched off. Could this indicate that there is something wrong with the power supply? Every time beocenter turns itself off it does that in a controlled way: it raises the tonarm and turns it away from the platter

Hello! I recently bought a Beocenter 7700 and I love the device! Everything is working with it and it sounds great, but when I play records or a cassette beocenter sometimes turns off randomly. Sometimes it plays the whole record but recently it has been turning off more often in the middle of the record. With tuner it hasn't done that. A friend
