Denon DRM 740 tape does not play

I recently returned from Peace Corps service and unpacked my stored Denon DRM-740 and found that the motor wont drive the tape when it is in play mode. The motor takes up the slack in the tape and then stops. In fast forward or rewind there is no problem driving the tape. What is the likely cause of the problem? How much repair likely cost? And is this a repair I could do on my own with little electronics repare expierence? Thanks. Ecuador PC

    i have the same problem with my drm-740. starts and shuts right off. problem is, that putting any amount of money into a tape deck in this day and age seems very silly. i hardly used the thing, paid way too much for it when i bought it, and now it doesn't work. should have bought what my brother bought, a yamaha tape deck. oh well, you live and learn-but if anyone has any suggestions, it would be nice to hear. btw, my nakamichi car deck always sounded better than the denon anyway.

    Mine is the DRM-700 model. FF and REW perfect, but press PLAY and the head engages, but the tape fails to move and the head disengages. Is this a drive belt? Perhaps the machines senses no tape motion and refuses to leave the head in contact with tape?

    Hello there,

    I seem to have a similar problem:

    After several years of not using the tape-deck, it now shows the following behavior:


    1. NO SOUND whatsoever in PLAY mode (whereas tape turns visibly)

    2. FF and REW work perfectly

    3. PLAY mode runs for about 5 sec and terminates itself

    4. pressing STOP in PLAY mode causes only a DELAYED (>2sec) reaction, whereas ins FF ans REW modes STOP works instantaneously.
    Certainly no 'dirt' or similar problem, more like an interlock or mechanical failure (head without contact to tape) is my guess.

    Thanks for any advice with better than 1 sigma chance

    1. When play is pressed the unit goes for a 6 count-NO sound then stops. Rewind ,ff, pause will not work during this time. If play is press a zillion times the unit then works. Ifit sits a few hours , back to the same old symptoms. cleaning heads,  pinch rollers does not help.

Just bought a unit from a thrift store. Found same problem; FF & RW OK, but play engages then stops. Also noticed buzzing noise when power turned on. Opened unit, found broken capstan drive belt. FF & RW driven from different motor. Buzz was drive motor running freely with no load - when power is on, capstan is driven all the time for fast play/record start. Replaced with rubber band, and it works --- now looking for replacement belt.

I have the exact same problem with my DRM 740 as the post above.

FFW and RW are fine, but once play button is pushed, the head engages then quickly shuts down.

I've cleaned the deck twice and no change.

The deck had been A-OK since day one prior to this problem.
Any suggestions before sending it out.

Thanks, Jack

There may be a separate motor for the play function and either it or a drive belt has failed.

Denon DRM 740 tape does not play


hmmm...sounds like the transport motor/foot are stuck..open it up, and inspect around those items(where the tape actually clamps down) and see if you can see anything in there. Might even be a bug, no fooling..

as to repairs..you are most likely talking some major money, and a long time in the repair depot, which I believe is in Rio..I'll check that for you while you do this part.

How to adjust speed denon cassette deck ?


There will be either on the motor or on the circuit board where the motor power comes from a preset. images below of what they might look on the board. One of these might be found in the motor, but hidden from view. All you might see is a slot in the bottom of the motor. This could be covered with a sticky label to prevent access.

Deck is running too slow


The unit either needs a new belt, Capstan bearing oiling as in taking the flywheel out and if this does not fix it a new capstan motor. The motor is adjustable with a small screw driver provided you have the appropriate wow and flutter meter and test tape to do the job.

Denon DRM-740 stops


This may mean the takeup reel is intermittent or that he cam system of the transport is not getting the correct feedback. I have hd some decks that had very little back tension and they would skew tape- and the audio would be gone before they would shut off. The deck need restorative work done to it and now is the time before is eats all your tapes up.

The pressure roller on my reel all of a sudden stopped and now when I press play it won't grab the tape and start but if I wait at some point it will start but then it releases the pressure roller back...


Sounds like a mechanical fault, you need to look around to see if anything has broken or fell off. Some decks use a solenoid to move rollers up and down, that could have a fault on it.
