So, I dismantled close to everything. What a mess.
followed the cable from the lid opening and cd buttons to the respective pcb.
attached and loosened it all several times.
assembled everything together and …
… nothing. No change. This beosound currently just wants to be controlled remotely.
Doesn’t want to be touched directly 😄
i think now, I need a replacement pcb, just don’t know which one.
i think I checked all TMs
best regards
