BeoVision 9 + 4x BeoLab 5, and suddenly installed thin Power Link cable (only left/right channel audio and speaker relay - brown coax, green coax and yellow, without white coax, grey and pink) to each speaker.

There is a terrible warning at user manual - IMPORTANT: Use fully mounted Power Link cables only – not the very thin type! If the wrong type of Power Link cables are used, the loudspeaker will not play. If in doubt, ask your Bang & Olufsen retailer.

Is there a acceptable solution without replacing cable?

Thanks!

The warning is true. The speakers literally will not play. You will need to replace the cable.

(How do you suddenly install cable?) 

Thanks a lot! I'll replace wires.

There are another speakers and tv was planned initially, so that thin powerlink was enough for initial installation.
