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
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

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:
Certainly no 'dirt' or similar problem, more like an interlock or mechanical failure (head without contact to tape) is my guess.NO SOUND whatsoever in PLAY mode (whereas tape turns visibly)
FF and REW work perfectly
PLAY mode runs for about 5 sec and terminates itself
pressing STOP in PLAY mode causes only a DELAYED (>2sec) reaction, whereas ins FF ans REW modes STOP works instantaneously.
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, Â pinch rollers does not help.
