That’s a logical explanation – I can’t think of any other reason for this anomaly. I would test this with mine but I don’t have a controllable input device other than the OneRemote radio which may behave differently.
Or maybe your DVD1 with the custom cable?
Another thought for tests if you feel like it. The Oneremote can be setup to AAL. Could it communicate directly with the BL3500? And maybe the same with the DVD1.

Good ideas – I will try all of them but not for a few days …

Great to get more inputs about this.
In the meantime I couldn’t let go of the idea of the datasignal in powerlink which seems to be couple with the MCL and AUX data signals in some products. I also discovered that in the Beolink Passive / ML/MCL converter the datasignals from powerlink and MCL is also connected, but with a couple of resistors betwen them. According to the user manual the ML/MCL converter should be able to drive MCL products from the Powerlink in a Beosystem 2500 (at least thats whats illustrated in the manaul)
As I don’t have any products with both powerlink and MCL connected internally I tried with the MCL2AV (where these signals are separated in the microcomputer) just to see if I got better results than the no reaction when I tried it with my BC6.
MCL2AV in option 1.5 where powerlink is active, and a custom cable to the BL3500:
MCL2AV pin 2 – > BL3500 pin 3, 5 and 7
MCL2AV pin 3 – > BL3500 pin 1
MCL2AV pin 5 – > BL3500 pin 4
MCL2AV pin 6 – > BL3500 pin 6
Tested with the setting ML off in the BL3500 service menu (Menu+0+9+GO)
Beocord 3500 conencted to the MCL2AV Tape connector
I can not activate the the Beocord from the BL3500. But if I start playback from the MCL2AV’s IR eye, I can use any audio command to turn on the BL3500 and the sound will play. Volume control is a little unstable. Somtimes the sound is very low, and I can’t control it, and sometimes its fine. I guess the volume on the MCL2AV does have to be at a certain level as the MCL connection on the BL3500 has some circitry to compensate for various volume in an MCL network.
So aperently the datasignals can’t be used for control in this case, but is enough to keep the BL3500 alive. Voltage on the data signals measured to 4,75V but again not sure it can be used for anything.
March 18, 2023 at 7:06 pm #17647I have 2 BL3500 – the one is working perfect with my Beolink 1000 remote. When I press MENU,0,4,PLAY it goes perfectly to “MCL SEL” Mode, and I can use the BL3500 as a passiv speaker with my philips TV.
No 2. show the “:” in the display when connecting to power, but it does not respond to the command MENU,0,4,PLAY, nore MENU,0,0 PLAY ore MENU,0,9,PLAY on the remote control?
I don’t know if I by mistake have disconnected no. 2 BL3500 somehow? Please – what am I to do in order to have no. 2 BL3500 to display “MCL SEL” and use it as a normal passive speaker?
Thanks for your help in advance 🙂

It could be that it is the MKII version with the Powerlink connector. The MKI has MCL engraved in the metal under the DIN connector, where nothing is engraved on the MKII version.
Try pressing MENU, MENU, 0, 4, PLAY and see if it helps? All these things require an extra menu press on the MKII version of the BL3500
March 18, 2023 at 8:06 pm #17649Hi Madskp
I have tried the double MENU, to see if it is a Mk 2 – but It is NOT. Under the Din connector MCL is engraved.
Earlier no. 2 BL3500 displayed “MCL SEL” when I pressed MENU,0,4,PLAY on the remote, but not anymore – very strange? 🙁
Still hope to find the reason for frosen BL3500 🙂
March 18, 2023 at 8:29 pm #17654You could try to press LINK, 2, STORE first just to be sure that its not in Option 0 (No IR).
not sure if it helps or if these Service menu commands works either way
March 19, 2023 at 7:06 pm #17688Thanks for all your help Madskp
I’m affreid this also does not help?
Please, where do you find the service manual with theese OPTIONS commands ?
I’m affreid that there is a problem the IR reciever in my unit? If so, where do I bye a new one, please?
All the best / Peter
March 19, 2023 at 8:03 pm #17693You can get acces to the service and usermanuals if you become a silver og gold member of Beoworld:
https://www.beoworld.org/what.asp
The servicemanual for the MKI version of the BL3500 is called LCS9000 servicemanual.
regarding spare parts I would look on Ebay, or maybe search for a donor unit locally
March 19, 2023 at 10:40 pm #17706Thanks a lot Madsko – 🙂
March 20, 2023 at 3:29 pm #17742Hi,
in the archived forum2 you can read a lot about the IR receiver problems and how to solve them. Mostly it’s about two SMD capacitors near the U2506 integrated circuit that need to be excanged. 🙂
I once replaced them in a Beolab 3500: Here
And here is a short description of how to replace the capacitors.
