Just got a hold of a near mint! condition Beolink 5000 MKI today, for aprox 100 euro's :)
The screen works 100%, but the display had been loose one point in time, and had been glued back on, the job was not very good, so i dissasembled the whole thing, took out the display (very gently so not to tear the connection), cleaned everything with water and soap, not the boards but all ruber button things/plastic and frame, it was all very greasy, but now everything is like new. I removed all the old tape from frame and display, and reatached the display using 2way bonding tape, like used when attaching carpets. Cut out fine pieces with a sharp knife.
I had a BL5000 from new in 1993 together with a BM7000/CD7000, and i feel like i in a timemachine now, its just like riding a bicycle, everthing is in the hands still, it is so easy to use, and i love my 2-way control with my recently bought BM7000/CD7000 again :)
