Dear enthusiasts

I have a Beogram CD 4500 which plays, spinns the CD. But unfortunately I don't get any sound.

Can someone give me a hint where a problem could be?

Best regards

Before investigating any likely problem from the unit itself, are you sure the lead to the amp' is not the source of the problem?

I was thinking that too. But how can I test the lead? I first thought that there are some broken soldering joints, but I could not find any.

I think the only way is to buy another lead. Worth it I think to find out where the real fault may be. I assume you don't have anything else connected, like the 4500 cassette deck? You could use that lead.

Testing the leads will be difficult on the 4500 sources as they are not interchangeable.

As you was checking for broken and bad soldering, you must have had the CD open. Now unplug the power supply, with a multimeter check that each cable strand has connection to a pin on the plug.

To which amp is the CD connected ?

It is connected to a Beomaster 7000.

Never did this before with a multimeter.Wink But I bought one yesterday. Big Smile

I tried to test the cable. But I am not sure if I did it correct. The multimeter shows different figures at each pin!

If your meter shows different values it only natural, it measures the resistance between the pins. If measuring from where the cable is  soldered in the CD to each pin, one of the pins will show 0.0 ohms or 0.1 ohm, make a note, then change to next pin/solder point, and if all pins/solder points shows 0.0 ohms your cable is OK, but if one of them shows mega ohms the strand is broken, so each soldered cable strand must have a 0.0 ohm to one pin, there may be less cable strands than pins, I dont know your model.

Check that the CD player is connected to the correct socket in the Beomaster.
