Denon DR-M44HX cassette deck play cutout after few seconds and tape transport does not move. Fast forward and rewind OK.

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.

Check the belts, inside the unit you should see a rubber belt which is what pulls the tape fast forward or rewind. Some belts with time get loose and slip, they can also break and fall off which will not let you fast forward or rewind.
Open your cassette player and look where the plastic pulleys are located and check for the belts, they might not be broken at all but very loose and slip on the plastic pulley.

Many cassette decks employ separate belts for fast forward and rewind. It could be that one of them has come off.

It sounds like the belt is slipping or broken which monitors the speed of the tape movement. When you play or rewind the tape, it thinks the tape has reached the end of play and shuts off. You can try a different tape to make sure the tape does not have too much tension on it. If the second tape has the same result you will need to remove the top cover of the deck to inspect the tape drive mechanism. Make sure the belts and pulleys are clean and replace any belts which have glazing or cracks. If the belt is broken you will need to replace it with a compatible belt of the same length and width.

Sounds like the cassette tape itself is too tight to play, try fast forwarding or rewinding the tape in the deck all the way to the end of tape several times before trying to play. This may solve the problem

Hi,
Does the tape move when you press rewind or fast forward.
If the tape moves for a few seconds then bleeps it sound like a sensor problem.
If it only bleeps when the rewind and fast forward are pressed and the play is ok it sounds like the actuator motor is faulty,this motor enables the rewind and fast forward.
Hope this helps.

Belts have become too slack to allow mechanism drive. Have replaced

Sounds like the tape tension sensor is stuck. The sensor is always telling the mechanism that the tape has reached the end.
