Hi, Mine has the same problem from the beginning, with a 2 way Beovision and a 1 way Beocenter. I also explored the "batteries way" with no success. I think it's software-related. The TV is gone, but the probem remains and I never found any way to solve it, unfortunately. So if someone can help, it would be greatly appreciated. Yann.    

I've seen that when using normal non-rechargeable batteries on the Beolink 5000s that I've renovated. The minus pad is often to small and create bad contact in the battery bay, especially the midle one. . Problem was solved by using rechargeable batteries (Ikea LADDA) where the minus pad is bigger.   Hope this can help.   /steffen

Thank you Steffen, I use Ladda batteries: I like to keep it all "nothern"! And I've add aluminium foil pads to secure the contacts.

I'd like to add tha I've some Beo 4 that exeperience similar issue: not reverting to one way of course, but stopping to work after some time. Dont know if it could be related.

Maybe a hint, Because of my setup (two Beosound Daisy-chained) and mu usage (once one, once the second, once both…) I need to fiddle with the "LINK" prefix key. Sometimes when I need to shut all down I make a long press on the "Stand-by" key that turn all off. I wonder if this do not make the remote revert to two way mode., because to change the mode, process say you must turn off the remote with a long press on "STBY".) barely similar to taking the batteries out and in the remote.
