Denon d-c30 cassette problems


I have a Denon d-c30 cassette/amplifier unit. When i turn the unit on, there is a clicking noise (for about 10 seconds or) from the cassette unit, before the unit will actually work. The radio and cd functions are fine, but one of the cassette decks won't open.....any hints or suggestions?

Re: Denon d-c30 cassette problems

That guy (Dries Hyman) has no idea what is he talking about. I have the same problem with my D-C30, and solution is simple, all you need its change the tape deck belt. (but, its very hard to access it if you going to do it by your self)

Re: Denon d-c30 cassette problems

Hi Craig,

I started my electronics "career" at the age of six. Will not bore you with details. Firtsly I would suggest that you check your power rails with a scope then follow the crackle in the usual way. Now what about dry joints or dry caps? If there is any semiconductors containing germanium, check them out. If aal else fail put the tape in the fridge for a couple of hours!!! Make use of a hairdrier to "prehaeat the unit. I used to do milspec and we worked at -40 to +55 centigrade. There might even be a noisy reistor in the psu.

King regards

Tape deck won't open or play.

If you have a cassette in the machine sometimes it will spew tape through out the mechanical sector and lock the door shut and won't play, the tricky part is to get the door to open, unless you can remove the outer shell "push up" might pop off, or set screws remove outer piece will come off. If not sure take it to a service shop.

The tape deck of my Denon D-C30 is'nt working, the drive belt is broken and when I switch on there is a clicking noise coming from the tape deck this stops after about 10 seconds and I can play the other ...

Actually when you switch on the system the set is trying to get back to rest mode but is not able as the motor dirve is not working due to the belt failure. The mode switch must be reset by the loading motor so that the system comes to a normal halt. So because this is not happening you must try to turn the mode switch to rest. Once this is done on switch on you will be able to get access to any mode but if would be good iff you can get the belt replaced so that on switch on the mode switch is reconfirmed. If you dont get any belt use a similar type of a band/ rubber /cord so as to make it run. So check this out. Good day

DC30 Denon cassette deck Drive belt broken Are spares available? Are there instruction on how to replace drive belts?

Hi J,

Sorry no solution for you. But I was wondering if you managed to fix yours. My D-C30 just has the same issue. 10 seconds of clicking and reading on another thread it sounds like the drive belt is broken and needs fixing.

Did you manage to find any instructions or spares etc to do this?

We can't get the power to come on.

Make sure that everything is plug into the right spot. If the amp comes on and nothing else, I will check the power cords. Also check the power buttons for each unit and make sure they are on. Also listen for a click sound from the amp when you turn it on. You will here it about 2 to 7 seconds after you turn it on with the main power button. If you do not here it, then you have a problem with the amp. One of the channels is bad and you will need to take to a repair shop for repair.

I dont know this system specially, but the speaker cables are usually heavy double cables with plugs on each end.

I would suggest that you visit a Dick Smith store and ask to see what speaker cables they have available...they are pretty standard its just the length and the plug socket match you need to make for the Denon model you have,

A Real Speaker Jacks..
There should be a switch position on your system that you move to allow the sound to come out to standard speaker configuration or to multiple speaker configuration.
This switch may be on the front or rear panel.

Please have alook to see if its there....
Its possible the these Real speaker jacks are not wired to anything inside the amp system, and are there for use on a different model where the selector switch is supplied.

B Cassett Deck..
The clicking is caused by the motor trying to drive the wheels that turn the cassett tape.
It sounds like something is jamming the internal drive mechanism.
The drive belt may have come off or is stretched and is slipping.

Have a good look inside the front slot and you may see one of these items described above happening..

It may have to be serviced at a workshop.

Cheers From YUBEUT.
