Cassette does not advance when playing,just continues to bunch up and sometimes gets tangled and ruins the tape.I took it apart and cleaned the capstan and roller bars and still have the same problem.Thank you Ron Martin

Re: Cassette tape does not advance when playing.
I assume you can see the tape move so its probably not the motor, from your description either the take up reel is not turning (which winds the tape back into the housing) or the capstan isn't moving. On some models this is driven by a belt feed, on others there is a "clutch" type felt pad. Without your model number it is hard to give a definitive answer.

if the take up side gets stuck it could feed excess tape and stop the mechanism. Look to see if both reels are turning when you push play. Remove cassette door for a better view if possible.
Make sure your tapes have NO slack in them. Fast forward and rewind one cassette all the way, then try again looking to see if both sides are turning. If not, you may have a belt that is old, stretched and slipping or it's split apart or just fallen off
You need to determine what is chewing the tape up. Most cassette doors clip off, this can often show the head and pinch rollers when they come into play. The pinch roller (the rubber one) is often the biggest cause of chewed tapes. But often it's the Take Up Reel that is not moving forward, so the tape is taken out of the cassette by the roller and spews out into the deck, getting tangled up in the roller. The roller itself can become worn and therefore doesn't make proper contact with the idler, or the idler (metal bar the roller pushes against) isn't turning caused by a belt that's broken.
The only way really is to observe what the tape is doing, but since this by definition means the tape could be chewed up, means you have to use an old tape that doesn't contain anything good on it. Make certain you can view as much of the workings of the deck mechanism as possible when using a test tape.
Since you don't mention the make or model number that is the best advise that any expert on here can give you.
This is an answer which is general to all tape cassette decks. I think it probably applies to yours but this may or may not be the case.
The tape is transported past the "read" head by a pinch wheel and spindle that come up into the cassette on either side of the tape. The spindle runs at a very constant speed and with the tape between this and the (rubber) pinch wheel sounds are transferred fro the read head to the electronics for amplification etc. We are not concerned with that here but with what physically happens to the tape after the pinch wheel. Under normal circumstances a belt is driven from the electric motor to the take-up reel of the cassette. This usually runs slightly faster than the spindle/ pinch wheel so that the tape winds cleanly onto the take-up reel. If this belt is loose, has come off entirely or is otherwise not working properly, then the spindle/pinch wheel will continue to feed the tape but it has nowhere to go because it is not being wound onto the take-up reel, except out of the cassette into the tape desk mechanism. In this case it often gets wrapped around the spindle/pinch wheel assembly and gets into a very nasty tangle, causing serious damage to the tape and possible damage to the deck.
Hope this explains your problem.
The speed should be adjustable but the common practice is to use a frequency counter and test tape or test tape and wow and flutter meter. I look at this from a Technician's point of view as I have been fixing units for 45 years so far. Once the motor speed control is found it does not take too long. Sometime it take more time taking the cover off.
I have not seen those to a large extent due to their value not being worth a repair. I did work on them at Teac though. The capstan motor of the right side deck sound like it is burned out. I have some motors here so it is just a matter of if you want me to work on it or not. I get a lot of units in all the time- I am Skywave Tape Deck Repair in Chicago area.
Probalby the only way to get stucked tape out of a player is in pieces. Then repair the cassette and clean your player. If it keep stcking tapes, dispose it.
By the way, cassette tapes an players are rather obsoleteby now. Any digital source is better quality the a cassette.
Hi, with the lid off operate the unit and see if drive still gets from the motor to capstan flywheel. Sometimes even although belts look ok, the have a buildup on the drive surfaces that will prevent it from applying enough tractive effort to the flywheel to engage the rolling mechanism. most of the hard work in ooperating the transport occurs when you select a function as the transport engages cam gears and followers to provide mechanical movement to engage the operation you have selected. You can fix this by cleaning the belt by running it across a cotton bud dipped in solvent (i use acetone, or iso alchohol),but replacing the belt is generally a longer term solution. If you need more advice then hitme back... happy to help
there is a mechanical problem in your tape deck. probably a losen rubber band. it clicks because the rubber is too lose to move the mechinal parts. so when you power off, it losen the whole machanical parts..it is very easy to replace..opend the deck and check it out..good luck
