Hi Tim

The problem should not relate to the EEprom or the CMOS battery, in my opinion, so better leave it as it is.

When the Beomaster comes on with a “CODE” in the display, the FM stations and soundsettings are not stored anymore the battery has to be renewed.

No sound on one channel on both speaker outlets is quiet uncommon, often the speaker relais fails. But the outlet “2” is connected directly to the poweramp section.

The Headphone is connected to the poweramp section too.

If you have a powerlink connected speaker you could check if these are running on both channels.

Switch speakers to INPUT L and INPUT R

If there is sound on both speakers (R&L) you have a problem behind the tonecontrol and preamp section in direction of the power amp section.

If one speaker fails on the powerlink outputs too there is a error in the preamp section.

Check this first and let us know what goes and what not.

 

The panels can be cleaned with this stuff:

I’ve made good experience and the old glue comes off in one go, please use only a creditcard or a spade of plastic, never use scraping metall spades or knifes, you will destroy the black coating.

After use clean with a household windowcleaner, no acetone or thinner your coating will be lost ;-))

 

For reglueing I use this double sided tape which is a little bit foamy but very sticky:

 

Be careful if it sticks to the glass it’s hard to get it of again, so look twice which plastic frame belongs to it’s place and align the gaps of the middle part.

I would never use 2 K Epoxy because you won’t get of the plastic frames from the glass even the glas is broken.

 

BTW

I’m not familar with the offers I linked here and get no money for comercial !

 

Kind regards

Nearly forgot to mention, had trouble with my BS 9000, IR was kompletely dead, not the funny “Option 1 ” konfiguration.

Read on the net about failing IR reciever where someone renewed a Cap on the IR board.

If you are a little bit handy and got a solder iron you could manage it by yourself.

Here´s the link I found:

Beosound 9000 – IR receiver repair

 

Let us know if you had any success.

Hi

Don’t know exactly what voltage shoud be on the motor, but most times the rubber belt of the geardrive is worn.

try to HELP the glassplate by hand (DO NOT FORCE just help) and look what’s happening.

How is the unit mounted? Horizontal wallmount?

Let us know…

Hi

About 1/2 hour is quiet a long time…

Does the Beosound react normal to operation with the pushbuttons on the unit itself in the first minutes?

Had quiet some strange behaviour when the glasplate is not mounted or the small IR detection parts  (small triangle plexiglas) and the glasplate are not clean.

Clean the glasplate from outside AND inside and clean the small plexiglas parts, maybe you’re lucky.

Sounds strange but….

Hi

Regarding to the confusion about the bearing maybe this gives a bit more light:

If you got the right belts and renewed / cleaned all the Idler Rubbers even the small ones inside the mechanism as chartz mentioned there is a mistake which I made for myself, I took just only one cassette for testing which did’t work, took another and everything was fine.

Are the transport wheels which grab into the cassette running free? Common problem is sized lubrication on the spindles.

Have a closer look for the breakarms, one grabs inside the transport wheel, easy to mount wrong 😉 don’t ask me why I know this.

If all is done and still no progress you could change one wheel after the other from your working unit to determine which part is causing the failure.

Hi Mick

Take a hairdryer or a heatgun (not on full power) warm the topplate on one corner and rip it off with a tonge part for part as you heat it up.

be careful, the glue is very strong and you can cut yourself on the shrp aliminium edges or hit yourself with the tonge if you slip of the aluminium.

Clean all glue rests of and get a sheet of brushed aluminium, cut it to size and glue back in place.

For me it worked well.

Schleift der Schlitten an der gesclossenen Scheibe?

Ist die Scheibe parallel zum Gehäuse ( Aluplatte) ? Wenn nicht kann man die Scheibe mit 2 Madenschrauben in der Höhe einstellen.

Hast du die Montage der Anlage von horizontal auf vertikal geändert? Wenn ja dann musst du die auf der Rückseite befindlichen Federn entsprechen einstellen.

Unbedingt die Scheibe von innen und aussen gut reinigen und die kleinen Plexiglas- Dreiecke ebenfalls reinigen, die sind für den “Fingerschutz” zuständig, hatte selbst schon Probleme damit.

Hi Josh

Two places where to get would be the “Beoparts” shop. If not listed online feel free to ask via Mail.

Same for ” kosetrading.com ”

I’m not family member of both shops and don’t get any money for advertising.

Kind regards

Hi

Try to reset the RAM ( all FM Stations will be deleted, sound options will be set to zero)  with the “TESTMODE” function.

How to get this testmode and reset RAM is discribed in the service manual chapter 7-10.

For me it helped quiet often if the behavior of the Beocenter is somekind “abnormal”

Let us know if you got success

Hi Mark

Thanks a lot for your suggestion.

Sure you’re right the Beogram panel is made of plastic. For my eyes it’s the same plastic of what the housing of the Beogram is made.

But as I see there is a diffenet colour on the control panel which , for me and my eyes, seems as a sprayed coating, same as on the Beomaster 6000 and 8000 panels wich are made of aluminium and coated with the same colour.

Maybe I go to a paintshop and ask for different colour charts and decide which comes next to the B&O colour.

Kind regards

Christian

Hi

If you got no luck with glueing the speaker search the net for

“Scan-Speak Discovery D7608/920000”

This is the right replacement and you can buy it new.

Had similar issue but with burned voicecoil, no repair possible.

Kind regards

Christian
