My Beolink is playing off randomly. Sometimes it stops working out of the blue.  (No infrareds  seen when tested with the  digital camera  trick). I try to tap it o touch the batteries  gently, but nothing happens. I leave it on the table and the day after it works, again ,  randomly.

Any thought?

Thanks

Sounds like a cracked solder joint. Small variations in temperature and movement can cause a no contact.
