BEOCENTER 9500 POWERS UP AND IMEDIATELLY TURNS OFF

9 replies

Dear people with knowledge

Poor ignorant in Crete Greece, 100's of miles away from a certified service. 

Two weeks ago there was one sudden power surge and then ofr a few hours we had no electricity.  I immediately pluged out my Beocenter.  The next day ... it will not start. It is on standby, any of the defferent sources get activated and then within a second it goes back to standby.   I downloaded the service manual and took it to a local service, he checked the fuses that are next to the transformer and said ok.   Any suggestions to avoid transfering it to Athens.

HI ourios

Please tell me if before this happened was the bc9500 always connnected to the mains.If that's the case your probem are related to the capacitors in the power section one ore maybe two of them can't "charge" any more,and also check the lithium battery

In the hope I am not being a pest, I would like to ask you, are there only two capasitors in question ? Are those visible. Since even though BC is in standbye mode and doors open and programming clock activateable, any of the sources, tape,cd,or radio dont operate.  Thank you again for your time

Have you checked the speaker wires? Or tried with speakers disconnected? If any of the speaker wires (or plugs) is shorted the protection circuit will turn the BC off. (I think so, haven't tried / seen but it might work that way)

 

Yes I have chechek the system with the speaker wires disconected.

Hi ourios

You now says that you can operate doors and timer.When you use the remote to change source(cd radio etc) does it change to the source,but no sound??

jan

Dear  Jan,

it turns back to standbye immediately, it does not gieve time to check if sound is produced not even with the radio. From the touch panel or from the remote the result is the same: a couple of seconds on and then  standbye again.

Hi there = If you go to the Workbench Forum and read the posts about the faults re the BM 6000 - a fault in the power supply etc, there are some good hints and tips which may apply to your problem.  Can you give us some idea of your technical ability, which would help us in advising you!  E.G. Have you a digital multi-meter and do you know how to use it? Regards = Brian (Northumberland)

Could be an amplifier problem but could also be a matter of cracked solder joints, I've seen this happen many
times, especially in the power supply areas and around the voltage regulators.

Sounds like a job for a trained tech guy.
