Beolab 6000

Strange one.... Bl6000 cuts off after a few hours off normal use.... Unplug and replug it plays again and so on.... Any ideas what this fault could be... Pwr link changed, power cable changed... Also tested on other set up and still switches on and off

This happens to BL8000s when the acoustic foam inside the speakers starts rotting and turning into an oily gunk. It erodes circuit boards. Maybe the same here?

All looks good inside, no sign of rot...burnt out circuits etc etc

Really struggling trying to figure it out, the last 4 weeks ok...then starts playing up, just shuts off so you turn off at source and give it 10-15 mins then ok till the next hour or so passes then off again[:\'(]
