Hi,

i’have bought a pair of Beolab 5 and for one for one of them I can’t complete the calibration. I starts, but then it stops and the led starts to flash green.

Any ideas what do?

Cheers,
PJ

1. Try a long press of the calibration button to reset.
2. When I had BL5s, they could only accommodate 10 calibrations before they locked up and needed a Service Engineer to clear the memory. I don’t know if this was Mk1, only or mk2?

Flashes green only? Looks like it didn't store the calibration parameters.

Could be a fault in a memory chip in the chassi.

Anyone knows if the IC304 is the responsible for storing calibration data?

Thanks for your replies ?

How can I identify if the memory chip is broken? Is it possible to replace?

Hi again, the investigation continues. I have tried to long press, nothing. I did try to calibrate once more:
  • The led starts to flash green
  • The mic comes out
  • Then nothing, no sound
  • The mic goes back
  • The led starts to flash red
Any genius that can help me?

Try to play the BL5. Does the lower woofer at the bottom vibrate while playing music?

Location: Utrecht

Quite a challenge to achieve "Less is More" while having the Beovirus.
