Bm 890 tape wont move in record or listen mode. will do fast rewind and forward

This sounds like a fault caused by a mode switch problem. The mode switch tells the electronic section what position the VCR mechanical section is in. The mode switch itself can go faulty, or it can be sent to the wrong position if the VCR mechanism is damaged. For example the mode switch might be in eject mode, when the mechanism is in play mode.
It's unlikely that a reset would cure the problem. But you could try powering down the video by pulling the plug and leaving for some time. Maybe even a day.
Mode switch replacement is only possible if you have either done this before or have the service manual. Since most mode switches are never ever set up in the eject mode position. The VCR mechanism will also need to be checked to make certain it hasn't been damaged before resetting or replacement of the mode switch.

here's the manual of this recorder. You can take a look at it to see if there are any explanations regarding the error:

take it back for a warranty refund and get a different machine

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.

maybe a broken break band on reel supply (left one) in the vcr !!!

brakes need adjusting on the reel hubs

Hello just get a really cheap foot pedal replacement at http://www.tvps.com/Products/ECS-Sony-IN-75-Heavy-Duty-Foot-Pedal---Pre-Owned__ECS-PIN-75.aspx

Its most likely the cam gear. Any sony dealer can replace the gear.

You probably have a bad power supply. But as you will learn, repairing any VCR will cost more than buying a new one.

look for a tiny pinhole and insert a pin while powered up to reset the device. if no-go, then the take-up reel needs attention...needs possibly a new or well-cleaned-with-alcohol-swab rubber belt
