Faulty Pioneer CT-W450R

There are sensors in the unit that are false triggering and some mechanical parts that require alignment. It can take two or three hours to put it back right if you are not familiar with that transport.
This is why I tell people to stay away from changers and auto reverse units as sooner or later they will be a real problem for someone to fix.

There are lots of causes to this. For example the mechanism has jammed. The tape has become entangled in the capstan or elsewhere. Plastic damage causing the mechanism to not move back to the eject position. Some decks have a powered eject that is faulty. Broken spring, or one that has fell off.

Reel motor drive or Idlers need changing

Usually on the back of the servo motor. You need a speed alignment tape and frequency counter or wow and flutter meter to do this adjustment correctly. Often times the speeds go up as the motor start to fail.

I'm not sure what country you're in but below is a link for a complete set of 5 replacement drive belts for your CT-506.

Please leave feedback.

Clean the Tape and erase head (these are the small block stainless and white plastic which the tape passes) with cotton ball slighty damped with rubbing alcohol

Have you tried contacting Pioneer for a list of their spares agents?

The rubber belts inside the unit have gotten stiff and slippery. All belts should be replaced. That will resolve the problem.

The belt drive unit is only ran by a SMALL rubber band. It may be that the actual band is broken or the motor itself is shot. Unplug the stereo from the wall and remove the cover CAREFULLY, look in at the tape drive and check the "RUBBER BAND" first.
