Anyone please?

I have connected and plugged in the BEOGRAM CD 50 : no lights come on

same thing with the  BEOCORD 5500

Neither is coming in standby mode

I have all connected to 5500 withe din cables , and 220 Volt is plugged in.

Have a look at the connectors for the Beocord and Beogram.  How many pins are present in the DIN plugs?

Each should have 7 pins.

The reason I ask is because sometimes people have removed the outer pins, reducing to 5, for use with other non-B&O amplifiers.

Thank you for the  clarification

 I have just jumped in to B&O with a given 5500 set pure , from an original installation in heavy smoking room condition!

nothing is mixed , all B&O

i have no idea how to get the cd and tape unit 'online'

Still no idea whatsoever. Just the Beomaster online.

Are there any fuses to check?

Where does the standby / tension signal come from for the Beogram CD 50 and the Beocord  5500 ?

All units should light up with a red standby dot when mains power is connected regardless of any interconnects etc.
If they don't do that, they will need electronic repairs (fuse and/or whatever).

That has been my guess since the beginning, but I needed to be sure.

thank you for the answer.

where do you suggest I look first , which component , a fuse ?

Fuses, yes.
And if a fuse has blown the reason must be investigated.
