My LX55000 still runs great. It says 1989 on the back but colours and everything works/sounds great.
Back in 2006 it arrived with a dead Beolink 1000 mk 3 and a L2800 floorstand which was great as the Beovision going out was an L2800 and I did not have a original stand for it.
The antenna plug broke so the local shop had to change it and update the software as it was the wrong type. I did take the screen of it to clean it, as it was very dirty behind it in the upper left and right hand corners. That helped alot.
The Beolink 1000 had 3 new Duracell's but dead, nothing at all on either the L28000 or the LX5500. However the 3 buttons on the LX did turn it on and change the channels. So quickly down to the local shop to get the Beolink 1000 fixed. Later on I got a electric stand a 2 way VX7000.
Now there was alot of extra goodies with the LX which was a bunch of Link cables and 2 boxes 1611 and 1615. As the LX still works great showing no signs of giving up it's been a great value for money for sure.
Good to hear that all LX mentioned here is alive and well!
