It sounds like it had a power surge.

Initially check the fuses .

Hi!

Please check for any blown fuses or burnt wiring.

    If you are using a any of these with it then check---



    Turntable - check for cartridges

    Tape deck - Belts both for the mechanism and the loading drawer, but these are readily available.Also, a 10 Ohm resistor in the power supply that is under-rated power wise and eventually burns out.


    CD player - if it stops reading discs, everyone assumes the laser has failed. 95% of the time they are wrong - the spindle motor lubricant dries up and means that the unit can't quite spin the disc fast enough to read it. Motor can be stripped and rebuilt but it's a nasty job and requires careful alignment when reassembling.

    Receiver - no problems known other than a propensity for the microprocessor to blow up if the unit suffers a lightning strike.

    After its been off for half an hour or so, check the output DC offset on each channel, which should be 11mV - this can drift with age



    Also see this link for Beomaster internal connections---

    Please ask for further clarifications.



    Thanks

    Also, check for a ribbon cable, you need to dismount the display and flip-down the front panel to gain access to the cable.

    And instead of them try using the discrete/single wires for connection.
    Make sure they don't get into a squeeze against the lower front frame chassis when closing the panel and take a note of the position and exact path of the string for the front panel dampener before taking it apart.

O.k. The Beomaster 5000 needs new Quiescent current presets , you can temporarily solve the problem by turning the two presets (in the main amplifiers) fully anti - clockwise .
Your beocord needs new belts for sure .. availiable from CPC of Preston .. Hope this helps ..

What type of speakers and turntable work best or will work with a Bang & olufsen 2400 reciever and 6000 reciever. thanks


I believe this Beomaster series needs amplified speakers that goes with it. You might use the RCA out and make it amplified with another receiver or amplifier and use ''usual'' passive speaker.

Hi...
Try one other thing..headphones. If there's only 1 channel in the headphones then you'll need to take it to a tech.
Depends on where in the country you are as to a good tech.
I know some...even me in the Northeast

Kenwood XD-A5 - "protection" shut off feature


This is a safety feature and can not be shut off. The system is detecting a problem in the last output stage of the amplifier and is shutting down to prevent further damage. I suspect a bad coupling capacitor in the pre-amp stage. This is a relatively simple repair for an experienced servicer. Figure on $10 or so for parts plus the local labor rate.

Protection displayed and shuts off


The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.
