Hi All

I have just acquired a BS9000 Mk1 & a pair of Beolab 5000 speakers. The BS9000 is working fine - as are the speakers & displays.

However the BS9000 responds to input via the manual keypad - but not remote. I have a BL 1000 and have entered SOUND - 1 - STORE whilst the unit is in standby. The standby LED doesn't blink and it still won't respond to the BL 1000. I have also tried with a Beo4. Mine is an early version & the display doesn't flash when you press standby & list - but I can get to 'A Opt.' and then press 1. Again no LED flash from the BS9000 & no response from either IR remote.

Any ideas anyone?

Thanks!

Have you tried with option 2?

You don't happen to have a plasma TV operating in the same room when trying do you? I assume probably not but a plasma display will jam the IR sensor on a BS9000 big time.

I'm afraid I'm recovering from the BeoVirus. Sad

Make sure the speakers are connected to the Beosound - I don't think it operates by remote if they aren't.  And make sure the remotes are working using a digital camera.

Hi - Thanks for the replies.

The speakers are connected - it all works fine using the manual keypad on the BS9000. The displays are working fine too on the BL5000.

There is no TV in the room. I have checked the remotes with a TV in a different room. Both appear to be fine.

Hi Machineage,

This may be a long shot, but is it possible that the speakers may be set to "Auto" mode instead of left or right?  It is a few years since I tried this, but I think from memory there is a quirk with the wiring on the Beolab 3000/4500/5000 speakers that lets them pick up audio from the Powerlink sockets when they are set to Auto mode, although they won't provide the current drain on the Powerlink trigger pin that the Beosound 9000 needs to see to operate via remote control.

One way to tell if this is happening is that the speakers would both be playing left channel audio, instead of stereo.  It is worth checking that the speaker switches are set to Left or Right, not Auto.

 Kind regards, Steve.

Thanks Steve

Yes I checked for this last night - and switched each speaker to L & R alternatively. I also swapped the leads - then tried one lead to one BL5000 & the second BL5000 wired from the first. No change when attempting Option 1 in any of the configurations Sad

Hi,

Thanks for this.  It does sound as though something is stopping the 9000 from accepting the option change commands if you are not getting the answering LED flash when trying to change this.  Why not try powering off the 9000 for a minute or so, then power it on, wait 30 seconds and try to set it to option 1 again.

Kind regards, Steve.

Thanks Steve

OK this is the procedure this morning. The BS9000 has been powered down & isolated since last night. The speakers have been in 'Audio' mode.

1) Unlplug the speakers from mains power

2) Move each speaker VIDEO / AUDIO / OFF switch to the OFF position

3) Connect each speaker to the BS9000 via PL Mk2 fully wired 8 core cables

4) Plug the speakers into the mains - note the standby lights now illuminated

5) Plug the BS9000 into the mains

6) Move the VIDEO / AUDIO / OFF speaker switches into the AUDIO position

7) Power the BS9000 up via the rear red push button. Note the speaker relays activating & the displays lighting up for a second whilst the standby lights extinguish - then the relays activating again & the displays shutting down - standby lights now illuminated. Note also a relay in the BS9000 activating - then de-activating - and the standby light now illuminated.

8) Attempt to switch to Option 1 using BL 1000 - point at BS9000 and press SOUND - 1 - STORE.

9) Nothing. No confirmation flash from the BS9000 standby light - no reaction to pressing CD or Radio on the BL 1000.

10) Try with Beo4 - press STANDBY & LIST simultaneously - Beo4 displays CONFIG? - press LIST until OPTION? is displayed - press GO - Beo4 displays V OPT - press LIST once - Beo4 displays A OPT - press 1 - Beo4 displays CD. No confirmation flash from the BS9000 standby light - no reaction to pressing CD or Radio on the Beo4 or BL1000

10) Press CD on the BS9000 keypad. Speaker relays immediately activate & displays light up - BS9000 activates & moves to the CD and starts playback. Displays both correctly display Volume / Track / Source data.

11) Wonders what could be at fault... Confused

If the above discribed procedure doesn't work, then the ir-PCB might be faulty.

During last year I've had 2 units with the same behaviour/ problem. Another PCB solved the issue.

I have to take some more time to investigate the boards, changed already the caps, but that didn't help.

I assume that you already cleaned the ir eye's?

Hi Beobuddy

Thanks for the reply.

Where are the IR receivers located and what would be the suggested method for cleaning?

Many thanks

Ahh - I located the IR receiver. The eye shaped IR filter is perfectly clean. Could it be dust on the actual IR receiver diodes - or could the board be at fault? 

I wondered if it may be the PL cables - but then I guess it wouldn't function using the manual keypad if that were the case...

Thanks

Hi,

That is unlikely, as the yellow wire in the Powerlink cable would need to be missing or broken for the 9000 to go into Option 0.  However, the absence of this wire would mean that the speakers wouldn't switch on.

However, if you want to try replacement cables to see if this does improve the situation, I'm happy to offer these with a 60 day money-back guarantee (ie. if you decide not to keep them, just post them back in good condition within 60 days for a full refund of the purchase price).  Here is the link to the fully-wired Powerlink mk.2 cables that you need for these speakers:-

As Steve suggests, without the proper cable the speakers wouldn\t start up and display any info. So, that's not the cause.

I hardly can imagine that the reception of ir is that worse blocked, but to eliminate the reception of ir, just check.

2 pictures where the ir-eyes are located. The second picture shows the the ir-eyes inside. These are often dirty when the BS9000 is mounted vertically.
