My unit is the CD75, I will post a picture once I open the player.


Thanks again.

Here are some pictures. I have noticed the big black capacitor slightly bulging, would that cause the issues I am having?


Can someone please point to the 'Control Processor' on the picture as mentioned by forum member that it could be faulty. many thanks.

I don't see a bulge, at least not from the angle at which the photo is taken.

The solution to your problem is unlikely to be as simple as just replacing that capacitor.

Buying a second hand CD player is a risky business. Did you contact the seller?

This player has been modified already! All the electrolytic capacitors have been replaced - in some cases with a much larger type which is in many cases a not so good idea. The PC board is a standard Philips board and the original capacitors are normally much smaller in size.

It's likely to be one of the larger black integrated circuits you can see in the photo, but I don't think knowing its location will help you much.

aboos suggested that there might be an intermittent contact which could be affecting the control processor - the source of the problem could be almost anywhere.

Intermittent faults are hard to pin down without access to test equipment.

As I type, aboos has posted that the player has been modified. Did the seller appraise you of that fact? If not, you have a good reason for contacting him.

Thanks for the feedback guys.


Yes I did contact the seller and he refunded me fully and told me to keep the player as he didn't want it back.


So no I have this player and want to try to fix it, (hoping it would be a fix like replacing a capacitor, otherwise it will be binned.


I also thought of buying another CD75 and see if I can make one good one out of two or would that be a no, no!

It's a jungle out there!

At least you appear to have encountered an honest seller who readily gave you a refund.

My advice would be to put the faulty player back at auction, at a very low starting price, descibed as being 'for spares or repair only'.

As I think you realise, without the necessary test equipment and technical skills, making 'one good one out of two' would definitely be a no, no!

Galu, thanks for your advice.


I will try to sell it on ebay.


I only bought this one as I really wanted to hear a CD with a TDA1541A DAC.


I'm still looking for a Marantz CD75, 65II or CD273 or whether to go for something newer like a Marantz CD63 SE KI as I do not want to go through the similar issue I had with CD75.


Now its about trying to find a genuine seller with a working unit at reasonable price.


Thanks guys for all the advice.

That looks like the basic Philips CD150 to me. The displays were a known problem and are essentially unobtainable today.

LCD readout - broken ? or bad joints

Someone did a brilliant conversion using a PIC (I think) and new seven segment displays to replace these.

Found it:
NSM4202A LED Display Module Replacement for Philips / Sony CDM Transports
